Abstract
A hardened bearing surface (36, 38, 42, 48, 50, 51 and 52) on a component (14, 16) of a rotary cutter drill bit (10) and the method of forming same. A composite mix (60) of alloy material (56) and base material (54) forms the hardened bearing surface (36, 38, 42, 48, 50, 51 and 52) with the alloy material (56) consisting of at least ten (10) percent of the adjacent base material (54) and of an optimum of around fifty (50) percent. The alloy material (56) of predetermined amounts of predetermined elements is positioned on the base material (54) and a precisely controlled high energy density source, such as a laser beam (58), melts the alloy material (56) and adjacent base material (56) to form the composite mix (60) defining the hardened bearing surface.
