Chen Rong, Zhang Guoding, Wu Renjie. The Affection of Alloy Elements on the Strength and Toleration of C/Al Composite Wires[J]. Journal of Materials Engineering, 1989, 0(6): 28-31.
The affection of alloy elements on the impact and tensile property of C/Al composite wires produced by means of CVD Ti-B coating has been studied. Interface bonding states of composite wires can be changed by the variation of alloy elements which affects the strength and toleration of composite wires in the same direction. Adding some Ti elements into Al matrix can increase the strength and toleration of composite wires and increasing contents of Cu and Zn elements in matrix has bad affection.
Sun Zhongzi, Liu hong, He Fei. Study on the Process of Copper Autocatalytic Plating of Plastics[J]. Journal of Materials Engineering, 1989, 0(6): 32-34,31.
Process of copper autocatalytic plating on ABS plastic, polyvinyl chloride, polyester film have been studied in this investigation. The composition, binding power, electrical resistivity and corrosion resistance of plating were analysed. The results indicate that the process of copper autocatalytic plating on plastics is simple. Property of plating is stable. It is suitable for conductive plastic and ground coat of other metal or alloy plating on plastics.
Wang Jiegan, Feng Zheng, Zhou Jianchu. Effect of the Morphology of Carbides in the Carburizing Case on the Wear Resistance and the Contact Fatigue of Gears[J]. Journal of Materials Engineering, 1989, 0(6): 35-40.
12Cr2Ni4A gear steel with a great quantity of disperse spheroidal carbides in the carburizing case has superior wear resistance and long life of contact fatigue. This kind of carburizing case can be obtained by multi-stage pre-processing technique. It is easy to manipulate, and the morphology of carbides obtained is better than that of foreign gears. Therefore, it is suggested to stipulate in the technical specification that a large quantity of disperse carbides should be existed in the case of heavy duty gears subjected wear.
