ABRASIVE BLADE TIP WITH IMPROVED WEAR AT HIGH INTERACTION RATE

摘要

An abrasive blade tip coating comprising a blade tip having a top surface. A plurality of first grit particles are dispersed over the top surface of the blade tip. A plurality of second grit particles are closely packed between each of the plurality of first grit particles. The second grit particles having a nominal size smaller than the first grit particles. A matrix material is bonded to the top surface. The matrix material envelops the second grit particles. The matrix material is also bonded to and partially surrounds the first grit particles, wherein the first grit particles extend above the matrix material and the second grit particles relative to the top surface.
