Abstract
Interaction of molten copper-silver alloy PSR-40 with stainless steel 1Kh18N9T is studied in relation to melt temperature (700-800°C) and contact time (10-40 min). It is established that alloy components diffuse into the steel. The depth of their penetration and the degree of interaction with steel increase with an increase in temperature and contact time. As a result of this with contact of the structural components to more than 20 min and a temperature above 780°C there is formation of chemical compounds with a higher hardness at the alloy-steel interface. Therefore impregnation in air for porous carcasses made from stainless steel 1Kh18N9T fibers with molten copper-silver alloy above these parameters is undesirable.
