| 摘 要： | 对超声波塑料焊机的声学系统连接界面破坏进行了分析研究。表明硬铝合金焊头极易发生表面的粘着磨损破坏，使得声学系统谐振特性变坏，效率降低。采用等离子体浸没离子注入（ＰⅢ）的方法对声学系统的连接面进行了氮的注入强化。高、低压的交替处理使得表面显微硬度提高６０％，而且在材料近表面生成了ＡｌＮ相，从而改变了其表面化学特性，使处理后的声学系统连接表面粘着倾向大大降低。

| Abstract: | The connection-surface damage of the acoustic system in an ultrasonic plastic welder is analysised. It is shown that the horn made of aluminum alloys(e.g.Ly12CZ) is apt to adhesion-wear,that makes the resonance properties worsening and leads to decreasing of the acoustic transmitting efficiency.The surfaces are treated using nitrogen plasma immersion ion implantation. After treatment alternatively with high voltage and low voltage implantation, the surface microhardness is increased by 60% and AlN phase precipitates in the near surface. Consequently,it substantially decreases the tendency of the adhesion-wear. |
