Abstract:
An erosion resistant coating adhered to a substrate to be exposed to erodent particles ringing in size from 32-300 .mu.m and having a known impact area comprising hard ferroboride phases interspersed within a ductile metal phase comprising a metal having a low affinity for oxygen selected from the group consisting of Cu, Bi, As, Sb, Co, Ni, Cd and Fe, wherein the majority of said hard ferroboride phases each have a surface area greater in size than said known impact area of said erodent particles and said ductile metal phase has surface areas of exposure between said hard phases, and wherein said ductile metal phase has surface areas being generally smaller in size than said known impact areas of said erodent particles.
