Abstract
A method for producing process equipment having a wear surface having extended resistance to one or more of abrasion, erosion, or corrosion, associated with fillers or solids processed by said process equipment includes applying to said process equipment wear surface a metal matrix coating filled with superabrasive particles. Diamond and cubic boron nitride superabrasive particles can fill the metal matrix, which can be a nickel coating.
