Abstract:
An abrasive coating for a substrate comprises a strike layer is formed on a substrate top surface; a base layer is coupled to the strike layer; a tack layer is coupled to the base layer, wherein the tack layer is configured to adhere first grit particles to the base layer; a plurality of first grit particles are adapted to be coupled to the tack layer, a plurality of second grit particles are placed between each of the plurality of first grit particles, the second grit particles having a nominal size smaller than the first grit particles; and an overplate layer comprising a matrix material is bonded to the tack layer; the matrix material envelops the second grit particles and bonds and partially surrounds the first grit particles, wherein the first grit particles extend above the overplate layer.
