Agglomerated anti-friction granules for plasma deposition

摘要

A collection of agglomerated anti-friction grains for plasma deposition, the grains each consisting essentially of (a) H2O 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.
