ABSTRACT:
A method of making anti-friction coated surfaces subject to sliding wear, comprising: (a) forming grains of agglomerated solid lubricant particles and air-hardenable, fusable ingredients such as steel particles, the particles being agglomerated by a low melting medium such as wax; (b) providing a light metal-based component surface; (c) thermally spraying such grains onto said surface in a thickness range of 100-250 microns to form a coating substantially devoid of the low melting medium (the temperature of said thermal spraying liquifying and eliminating the wax by ash-free combustion); (d) removing at least a portion of the fusable particles by honing to expose edges of such particles; and (e) subjecting the exposed particles to air hardening (i.e., by available interfacing friction).
