    摘要: Fine metal alloy powders coated with a protective film are disclosed whichre produced by the gas atomization process. The protective films are formed during the gas atomization process by gas atomizing a molten mixture of a metal alloy containing an alloy addition agent in an atomizing gas which will selectively react with the alloy addition agent to form a thin protective film on the surface of the metal powder.
