Abstract
A metallic coating containing hard carbide particles is described. The coating is applied by an HVOF process using powder particles whose size ranges from about 15 to about 44 microns. The carbide particles are held in a 80% nickel-20% chromium matrix. The coating has a reduced tensile compressive stress relative to similar plasma sprayed coatings and exhibits a high strain to cracking value.
