on the reflectivity of bulk material[5-9]. DC (direct current)-plasma jet surface metallurgy is a new high developing technique and an effective material processing method that produces surface metallurgical coatings... Experimental Fe-based alloy powder was used as the coating material. The particles of the Fe-based alloy powder were less than 150 μm in size and are spherical in shape. Table 1 shows the chemical......
material, Ag/SnO2+La2O3+Bi2O3, was produced by the powder metallurgy method. Its properties are as follows: the density is 9.75-9.93 g/cm3, the resistivity is 2.31-2.55 μΩ·cm, the hardness is 880-985...A new contact material-Ag/SnO2-La2O3-Bi2O3LU Jianguo, WANG Jingqin, ZHAO Jingying, WEN Ming, WANG Baozhu, and WANG XiaohongInstitute of Electrical Apparatus, Hebei University of Technology, Tianjin......
