Surface reinforcement of iron-base materials

Conclusions A study was made of the application of a wear-resistant TiC-Kh12M steel layer to type 45 steel by methods consisting in simultaneous pressing and sintering and in the sinterbonding of a pressed or sintered layer to a sintered base. It has been established that the alloying of the basis material with 1% of Cu substantially increases its density and adhesion to the coating. It is shown that a layer can be applied to a sintered base with or without a substrate. It has been found that the highest bond strength, (10–14.3)·10⁷ Pa, is attained when a layer and a base containing 1% of Cu are simultaneously pressed under a pressure of 3.10⁸ Pa and then simultaneously sintered at 1673K.Translated from Poroshkovaya Metallurgiya, No. 10(238), pp. 33–38, October, 1982.
