Abstract: A bushing (100) for a track assembly includes a tubular bushing substrate (110) having a longitudinal length and an outer surface (112). The outer surface (112) includes at least one flat portion (134). The bushing (100) also includes at least one white iron member (120). The at least one white iron member (120) includes a flat inner surface (132), and the flat inner surface (132) of the at least one white iron member (120) is fixed to the flat portion (134) of the outer surface (112) of the tubular bushing substrate (110).

Abstract: A method for coating a component of a track roller frame track tensioning and recoil system is disclosed. The method includes irradiating a surface of the component with a continuous laser to heat the component's surface. The method also includes coating the surface of the component with a thermal spray coating after irradiating.
