Abstract
A collection of agglomerated anti-friction grains for plasma deposition, the grains each consisting essentially of (a) H.sub.2 O atomized stainless steel particles, (b) solid lubricant particles consisting of at least one of boron nitride or a eutectic of calcium fluoride and lithium fluoride, and (c) a binder holding said steel and solid lubricant particles together for plasma spraying, said binder being present in an amount of 0.5-4.0% by weight and is vaporizable at the temperature of plasma spraying and does not interfere with the deposited process.
Claims5
Granules of agglomerated powder particles, consisting essentially of:
- (a) water atomizod stainless steel particles, said stainless steel particles consisting essentially of, by weight, 0.1-0.4% carbon, 1-8% manganese, 1-5% nickel, 1-15% chromium and the remainder essentially iron;
- (b) solid lubricant particles consisting of one of boron nitride or a eutectic of calcium fluoride and lithium fluoride, said solid lubricant particles having a particle size of 10-40 microns;
- and
- (c) a binder holding said stainless steel and solid lubricant particles together in a granule, said binder being present in the amount of 0.5-4% by weight of the granules and vaporizable at the temperature of plasma deposition.
