| Generation Mechanism and Control of Coating Defect of High Melting Point Metal Arc Spray Tooling |
|
|
|
|
Abstract In the forming process of high melting point metal arc spray tooling, defects usually appear, such as cracking, warping and swelling. Residual stress in high melting point metal coating is an important reason for coating defects. The position that easily produces defects is the weak part. Optimizing spraying process, adding binder surface or reducing stress concentration could effectively reduce and eliminate coating defects.
