A thermally sprayable powder having grains comprising: a core of solid lubricant particles comprised of at least graphite and MoS 2 (others may include Bn, NaF, LiF, CaF 2 , and WS 2 ); and a thin, soft metal shell (Ni, Co, Fe, Zn, Sn, Mg, or Cu) encapsulating such core. Some core particles may also be hard, wear-resistant particles from the group consisting of SiC, NiCrAl, FeMn, FeCrAl, FeWNiVCr, NiCrMoVW, FeCrMoWV, CoFeNiCrMoWV, NiCrMoV, and CoMoCrVW. |
