摘要

A PROCEDURE FOR THE CEMENTATION AND GASEOUS CARBONITRURATION OF MECHANICAL PIECES OF STEEL AND SINTERED PARTS OBTAINED BY ANY METHOD OF POWDER METALLURGY, characterized in that it consists essentially of introducing simultaneously in an oven and in variable quantities, adjustable according to the needs of the moment , a cementitious liquid of organic character capable of yielding carbon in appreciable amount and air to a slight overpressure, which produces the double effect of causing partial and directed combustion of the organic cementitious liquid and diluting with nitrogen the atmosphere thus generated favoring the reactions of incorporation of carbon on the surface of the mechanical steel parts, properly so called.
