试验研究了不同含量的两种碳化钨粉末对镍基自熔合金喷熔层耐磨性的影响。
Effect of type and content of WC on the wear resistance of Ni base spray melt layers were studied.
先采用自熔性好的合金激光熔覆恢复尺寸，再用激光合金化强化表层。
Dimension was resumed by adopting good self - fluxing alloy laser welding technology, and then the surface was enhanced by laser alloying technology.
结果表明，经过固熔处理后，铝合金电极的电化学活性得到显著提高，但自腐蚀速率加快。
The results show that the electrochemical performance of aluminum alloy electrodes is improved markedly after solution treatment, but the self-corrupt speed of electrodes is accelerated.
