摘要
针对直流脉冲负偏压对PVD涂层形成过程和熔滴造成很大影响的问题,通过施加脉冲偏压有利于实现低温沉积.研究发现,沉积速率随直流脉冲负偏压峰值的提高先升高后降低,在-300V偏压时沉积速率最大;熔滴密度和直径随脉冲负偏压峰值的提高递减;随偏压升高,加大了元素溅射产额的差异,使涂层中铝元素和钛元素的含量发生变化.
Multi-arc ion plating is widely used to deposit hard coatings. The effect of the DC pulse-bias on the growing processes and the droplets is considerable. The research shows that the depositing rate increases at first and then decreases as the peak value of negative DC pulse-bias increases gradually. The maximum rate locates at -300 V. The density and diameter of droplets formed during the coatings growing become low and small when the pulse-bias increases. The ratio of titanium and aluminum in the coatings will change, and the low temperature deposition will become easy as the negative pulse-bias is employed.
