J0401-1-2 The applied study of WC-Fe cermet material for cold spray

From the appearance of HVOF thermal spray system on 1980s, WC cermet coatings have been used as an antiwear coating in many industrial manufacturing. Recently, WC cermet spray materials were applied to new thermal spray method such as Warm Spray and Cold Spray under research phase. The research target of spray materials were standard contents such as WC-Co or WC-Ni used by HVOF. However, there is a potential that any other WC cermet materials are better for Warm Spray and Cold Spray because the characteristics of metal binder is conclusive factor. In this study, WC-Fe alloy cermet spray material was sprayed by cold spray to investigate the influence of Fe alloy binder. The results indicate that the WC-Fe alloy cermet material is better than standard WC-Co in spray efficiently and coating properties.
