For digital measurement demands of the structure and equipment installation in the internal and external
regional space, the associate technology of inside and outside reference points is researched. The internal measurement accuracy
field united with the external measurement accuracy field is constructed. With regard to different openings between
inside and outside spaces, utilizing the multi-spotting method, two measurement points and a level single-station positioning
method, two measuring points and a level two-station positioning method, internal precision field is established to
achieve the unity with external precision field. In a certain type of equipment, for example, experiment results show that the
inconsistent measurement error of the same checkpoint between inside and outside measurement accuracy fields is up to 0.14
mm, which proves that the build mode is feasible, simple and reliable.

DU Liqun1,2, TAO Yousheng1, LI Yuanqi2, QI Leijie1
DOI: 10.16080/j.issn1671-833x.2017.14.024
Based on the electrochemical deposition technique, a new passive MEMS inertial switch was fabricated
on a metal substrate. In view of the problems of poor quality caused by the serious lateral erosion of SU-8 in the process
of making high-aspect ratio and fine-line micro electroforming molds, SU-8 UV lithography was studied. The effects of
different exposure dose and PEB (post exposure bake) time on SU-8 UV lithography were studied experimentally, and the
parameters of UV lithography were optimized. By using the method of reducing the exposure dose and prolonging the PEB
time, the problem of poor quality of high-aspectratio and fine-line SU-8 electroforming mold was solved successfully. Finally,
on the basis of the above experimental results, a passive MEMS inertial switch with high-aspect ratio was developed.
The external dimensions are 3935μm×3935μm×234μm, of which the smallest line width is 12μm, the highest aspect ratio
of the single layer is 10∶1, and the highest aspect ratio of the multi-layer is 20∶1.

LUO Yi, YU Zicheng, JIA Chen, WANG Xiaodong
DOI: 10.16080/j.issn1671-833x.2017.14.032
The flat micro heat pipe, a new type of heat transfer devices of gas-liquid two-phase flow, has more advantages
in the application of thermal control system with compact devices in the limited space, but its performance still
has great room to improve. On the basis of analyzing the working medium transport characteristics of flat micro heat pipe
with steam chamber, the micro heat pipe with a dimension of 45mm×16mm×1.75mm is designed and fabricated. The depth
of the steam chamber is 200μm. A micro heat pip in the same size without steam chamber is fabricated to compare the heat
transfer performance. Experimental results show that when the temperature difference between simulation and experiment
is around 10%, the images collected by high speed image acquisition system can be well in accordance with the simulation
results. When the input power is 6W, the balance temperature of heat pipe with steam chamber is 70.4℃ while the heat pipe
without steam chamber is 118℃ . Meanwhile, the equivalent temperature with steam chamber under the input power from
1W to 6W is lower than without steam chamber. Hence, the stream chamber has a great influence on reducing the gaseous
medium circulation resistance and improving the ability of heat production. The research work of this paper can provide
reference for optimization design of flat micro heat pipe.

LIU Xiaomeng, BAI Jicheng
DOI: 10.16080/j.issn1671-833x.2017.14.037
Accurate identification of micro-EDM discharge state is an important guarantee for high-precision and
high-efficiency machining. However, the micro-EDM pulse energy is small, the discharge frequency is high, the process is
random, which seriously affect the identification accuracy of discharge state. In order to solve this problem, the characteristics
of micro EDM discharge state are studied, and the reasons of each discharge state are analyzed. At the same time, the
discharge state is identified according to the difference in the discharge state characteristics. By setting the inter-electrode
voltage threshold, the inter-electrode current threshold and the spectral threshold, the accurate and effective identification of
the no-load state, the spark discharge state, the stable arc state and the pulse interval is realized, thus providing the basis for
efficient servo control.

ZHANG Xin1, WEN Peigang2
DOI: 10.16080/j.issn1671-833x.2017.14.054
In order to investigate the influence of laminate periodicity on hardness and wearability, CrNx/TiyCr1-yN
coatings with 5, 13 and 26 periodic multilayer are prepared on AM355 steel substrate by metal evaporation vacuum arc ion
source (MEVVA) and filter cathodic vacuum arc deposition technology. The morphology and phase structure of coatings
are observed and analyzed by field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD) respectively.
The hardness of coating is tested by microhardness tester and the bond strength is measured by scratch tester. The
results show that CrNx/TiyCr1-y coatings with multilayer have dense structure and good bond strength. With the increase of
laminate periodicity, the hardness of multilayer decreases while the bond strength shows a trend of increasing at first and
slowly lower later.

DOI: 10.16080/j.issn1671-833x.2017.14.072
Wire+arc additive manufacturing (WAAM) system for Al-6.3Cu alloy using hybrid pulse variable polarity
gas tungsten arc welding (HPVP-GTAW) process was established. The geometry of Al-6.3Cu single-pass multilayer deposits
influenced by wire feed speed and travel speed, microstructure and tensile properties of deposited samples produced
by the conventional VP-GTAW and HPVP-GTAW process were investigated. Experimental results show that the effective
control on deposits geometry is obtained with the coordination of wire feed speed and travel speed. The internal structure
of Al-6.3Cu deposits shows the typical layered distribution characteristics, mainly composed of equiaxed grains. WAAM
samples with as-deposited condition have good plasticity, but the relatively low strength. Compared with conventional VPGTAW
process, it is beneficial in enhancing the strength of Al-6.3Cu deposits using HPVP-GTAW process.

DOI: 10.16080/j.issn1671-833x.2017.14.077
Studying on the tensile mechanical properties of butt joint of 2.5mm thick TC4 welded by fiber laser, of
which research method is applying synchronous infrared thermal imaging in conventional tensile experiment, real-time according
the change of temperature field of specimen in tensile experiment. Conventional tensile experiment results show
that the welded joint has similar strength but of which the elongation rate just reached 59.53% of base material. The specimen
temperature field test results show that: when the axial loads is below the load corresponds to the yield strength, larger
yield strength area appears in the heat affected zone of welded joint, but significant plastic strain did not appear. When the
load is equal to the load corresponding to yield strength, the micro plastic deformation appears before macroscopic yield
point. When the load is equal to the load corresponding to tensile strength, the length of severe plastic deformation zone
of joint reaches only 35% of the base metal, and the length of severe plastic deformation zone gradually increases with the
stretching process.

DUAN Huifen, LIU Zhijian, YU Haoran, HUANG Haifeng
DOI: 10.16080/j.issn1671-833x.2017.14.082
In this paper, we have prepared Mg-Li based composites reinforced with boride by in situ synthesis. For
mechanic properties of Mg-14Li-1Al-1Y based composites cannot meet the requirement of industrial applications, the
research has prepared composites reinforced with boride based on Mg-9Li-1Al-1Y (its composition is (Mg-9Li-1Al-
1Y)-6B4C). The effect of Li content on microstructure and properties of the matrix alloys and composites were studied.
The results show that compared with Mg-14Li-1Al-1Y, the dual phase microstructure of Mg-9Li-1Al-1Y is finer and the
mechanical properties are improved. Compared with Mg-9Li-1Al-1Y, the hardness and the tensile strength of (Mg-9Li-
1Al-1Y)-6B4C are enhanced by 66% and 31.33%, respectively, while the elongation decreases by 15.5%. Compared with
(Mg-14Li-1Al-1Y)-6B4C, the yield strength of (Mg-9Li-1Al-1Y)-6B4C decreass by 15.4%, the hardness increases by
29.3%, and the tensile strength and elongation remains unchanged. The above experimental results show that the mechanical
properties of composites have not been improved with the deduce of Li content. It does not reach the expectation that
composite strength can be improved with strength increase of corresponding alloys. The matrix strengthening is too weak to
reflect in comparison to the second phase strengthening and fine-grain strengthening of Mg-Li based composite reinforcement
mechanism.

DOI: 10.16080/j.issn1671-833x.2017.14.093
Applicability of surface residual stress on the complex components of TC4 titanium alloy using X-ray
testing is researched by simulating the test surface state of structure based on four points bending machine loading of titanium
alloy plate specimen and high strength titanium alloy standard sample. The datum show that surface curvature and
range of beta angle do not significantly affect the results. When the radial test surface inclination is larger than 20 °, the test
repeatability is drastically changed, and the result is not available when more than 30°. The result cannot be applied as surface
inclination is greater than 30°. The result decreases with increasing axial angle, which decreases more than 20% when
axial angle is 30°.
