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.
Claims17
Process equipment, comprising:
- a substrate, and
- a filler material process wear surface coated with a coating comprising a metal selected from the group of nickel or nickel alloys and superabrasive particles comprising synthetic monocrystalline diamond;
- and
- one or more of hexagonal boron nitride (hBN), SiC, Si3N4, WC, TiC, CrC, B4C, and Al2O3;
- wherein said superabrasive particles are between about 0.1 microns to less than about 50 microns, and wherein the coating has a thickness from greater than about 2 microns to about 1000 microns.
