【Abstract】 The preparation and behavior of Zn Al Cu pseudo alloy coating in die & mould manufacturing by electro arc spraying are studied, and its structure, constituent, and the influence of SL building material on coating hardness are analyzed. The results indicate that coating hardness can be increased when the contents of Al, Cu and Mg in coating are higher than their preliminary composition in the Al Cu Mg alloy. The coating hardness is determined by its structure and especially the stress condition. The less the absolute value of residual stress in intermittent spraying is, the less the work hardening and hence the hardness is.更多还原
