Abstract

The method is used for producing powder metallurgical products for mechanical engineering, instrumentation and the power industry. By it, liquid phase of lower sintering process temperatures is formed without any need for using an element for reducing the melting temperature of the basic metal. The fired products have preset content of carbon, even structure, high density and physicomechanical characteristics. The method comprises the moulding of products from initial powder metal (powder mixture) and sintering. Before moulding, the particles of the initial metal powder (powder mixture) are covered by a layer of a substance, containing carbon and Hydrogen of gross formula CmHm, wherein m and n have values from 6 to 12, and m is equal or different from n. The optimum value of m and n is 7 or 8. 7 claims
