An iron or copper based metal powder useful for plasma deposition of a coating that has a dry coefficient of friction 0.75 or less and readily conducts heat through the coating. The powder comprises (a) H.sub.2 O atomized and annealed particles consisting essentially of (by weight) carbon 0.15-0.85%, oxygen 0.1-0.45%, an air hardening agent selected from manganese and nickel of 0.1-06.5%, and the remainder iron or copper, with at least 90% of the particles having oxygen and iron or copper combined in the lowest atomic oxygen form for an oxide of such metal. A method of making anti-friction iron powder that is economical, selectively produces FeO and promotes fine flowable particles. The method comprises (a) steam atomization of a molten steel that excludes other oxygen, the steel containing carbon up to 0.4% by weight to produce a collection of comminuted particles, and (b) annealing the particles in an air atmosphere for a period of time of 0.25-2.0 hours in a temperature range of 800.degree.-1400.degree. F. to reduce carbon in the particles to about 0.2% or sponge iron by reducing Fe.sub.3 O.sub.4 or Fe.sub.2 O.sub.3 in CO and (H.sub.2 O steam) to attain nearly all iron with nearly all FeO and 0.1.degree. to 0.85.degree. C.

A high efficiency pump having relatively-moving parts constituted of a light weight material and a coating on at least one of the parts to effect essentially zero clearance between the parts where they merge together. The coating is comprised of solid lubricants in a polymer resin matrix stable up to 700.degree. F.

Method of making an efficiency enhanced fluid pump or compressor

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.

Solid lubricant coating for fluid pump or compressor

A process for making and assembling a rotary regenerator comprising a ceramic core adapted to rotate upon its central axis and a ring gear surrounding the periphery of the core for purposes of driving the core rotatably including preparing and forming a yieldable compliant ring sandwiched between the ring gear and the periphery of the core to prevent stresses in the core caused by differential rates of expansion of the core and the ring during operation of the regenerator in a gas turbine engine and during processing of the regenerator and the regenerator drive ring.
