【摘要】 <正> 一、前言目前,塑料制品表面真空镀膜有蒸发法和磁控溅射法。蒸发法是在10^-4～10^-4托的真空中加热镀膜材料,使之瞬间蒸发,沉积到塑料制品表面。通常蒸发材料是采用象铝那样的低熔点金属。磁控溅射法则是在5×10^-3～5×10^-4托的压力和氩气气氛下,利用高效磁控管溅射源进行真空溅射,使溅射材料凝结到被镀件的表面而形成镀膜。磁控溅射法能镀铝和黄铜,也能镀紫铜,不锈钢等。塑料真空镀膜为玩具、灯具、工艺美术品、更多还原

【Abstract】 In order to make the metal meta-llized in plastics surface effective,undercoats and topcoats have to beused.The rapid development of pla-stics vacuum metallization in recentyears owes greatly to the use of ad-vanced undercoats and topcoats.The paper deals with these two ki-nds of paints and gives possible de-fects in application and their reso-urces.更多还原
