Abstract: The infiltration of NiCrBSi and CoCrW coating alloys on various base steels has been investigated systematically in this paper by means of vacuum fusion,scanning electron microscope,electron probe and X-ray diffraction techniques. A quintic equation between the condensation contact angles and the boundary face concentration difference in Fe element has been proposed by measuring the condensation contact angles of melted coating alloys on base steels and analyzing the elements diffused between them. The mechanism of infiltration process and the influence of temperature, medium and chemical compositions have been discussed. Finally, it has been shown that the infiltration is a macro manifestation of diffusion at the boundary face and a prerequisite to form firm metallurgical bond.
