Thermally spraying metal/solid libricant composites using wire feedstock |
摘要 |
A method of the thermally spraying a solid lubricant (i.e. graphite or BN) impregnated metal matrix onto a metal target, using the steps of: (a) creating a flame or arc into which a consummable strand is fed, the strand being constituted as a hollow sheath of metal and a core therein comprising essentially solid lubricant powder particles, the flame or arc melting the metal of such strand; (b) applying a pressurized jet of atomizing gas to the melt and included graphite particles to project a spray of molten heavy metal and graphite particles generally homogeneously distributed throughout such spray, said graphite being protected against ablation during transit from the flame or arc to the target; and (c) surface heat treating essentially only the deposit to precipitate additional graphite while densifying the metal and controlling microstructure. |
