Abstract：Using water jet peening to strengthen local area of high-hardness carburized and quenched parts is a promising technology for surface modification. This paper focuses on the application of surface layer modification, and introduces the characteristics and applications of pure water jet, injection and suspension water jet in turn. On the basis of comprehensively comparing the characteristics of various jets, it is proposed that the suspension water jet is an ideal jet method in surface modification, and the problems existing in the modification of the suspension water jet peening are discussed. The jet formation, parameter measurement, nozzle shape and service life need to be further studied. Moreover, the surface integrity of modified layer, the fine process after water jet peening, the effective modification of high stress concentration area, the continuity of the formation of jet, and stability and other issues need to be concerned. On the basis of solving the above-mentioned mechanism problems, as well as improving the jet modification equipment, engineering application research on specific parts such as gears, blades, and spline shafts can be carried out.
