Friction Behavior of HVOF Thermal Spray Coating of Micron Size WC-Co Powder
High velocity oxy-fuel (HVOF) spray coating of WC base cermet has been studied as a promising candidate in some hard coating area for a replacement of the long traditional electrolytic hard chrome (EHC) plating, which has been raising public health and environmental problems. Micron size WC-Co (mWC-Co) has been coated on Inconel 718 substrate by HVOF thermal spray coating process. Surface properties of coating layer and friction behavior have been investigated for durability improvement coating on the sliding machine component surface.
