Generation Mechanism and Control of Coating Defect of High Melting Point Metal Arc Spray Tooling
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.
