Abstract

The wetting processes and contact interaction of metal melts and ceramic materials based on tin dioxide (SnO2, SnO2—1% (at.) Fe2O3, SnO2— 0,5% (at.) CuO) were studied in gaseous environments with different partial pressure of oxygen in the system (air, pure oxygen). The concentration dependences of the wetting contact angles of ceramic surfaces for a number of metal melts (Ag—Cu, Ag—Ge, Ag—Pb) with oxygen dissolved in them to equilibrium state were obtained. The microstructure of the ceramic-metal contact zone was investigated.
