Injection particles forming it with cermet coating, cermet coating forming method, film-forming product

摘要

The present invention aims to provide an injection particles forming it with cermet coating was able to take advantage of further stiffness possessed by the hard reinforcing phase powder. The cermet coating is a cermet film formed on a substrate surface composed of the binder phase and hard strengthening phase, whose Vickers hardness is less than 100% more than 50% of the hardness of the hard reinforcing phase powder has and that,, (Ra center line average roughness) the surface roughness is less than 3.0, in the cermet coating, heat the injection particles and binder phase powder with hard reinforcing phase powder is agglomerated Using the means and characterized in that formed the hard reinforcing phase powder is integrated by the binder phase powder Te is sprayed onto the substrate at supersonic speeds.
