Abstract

A method of making articles of greater resistance to corrosion, with metallic powder, comprising: pressing said powder into a crude compact; sintering said compact in a substantially non-oxidizing atmosphere, to form a sintered article; impregnating at least the surface of said article with an alkali metal silicate, and curing said silicate.
