【摘要】 利用加弧辉光离子渗镀技术对工业用Ti-6Al-4V钛合金进行离子无氢渗碳,在改善钛合金表面摩擦学性能的同时还有效地避免了其它有氢介质渗碳所产生的钛合金氢脆问题,是一种新的钛合金表面改性技术。本文主要介绍了加弧辉光离子无氢渗碳的原理,并着重研究了不同温度、不同靶距条件下钛合金表面粗糙度的变化情况。研究表明,高温加弧辉光离子无氢渗碳在一定程度上使得钛合金的表面粗糙度变差,其中渗碳温度和靶距的影响比较明显。更多还原

【Abstract】 Using the technique of the arcadded glow discharge plasma nonhydrogen carburizing,carburized layer on the titanium alloy (Ti6Al4V)surfaces was formed.The tribological property of titanium alloy surface was enhanced notably,at same time,titanium alloy avoids the problem of hydrogen brittleness.It is a new titanium alloys surface strengthening treatment.This paper introduces the principle of arcadded glow discharge plasma nonhydrogen carburizing.The surface roughness of titanium alloy with nonhydrogen carburizing was main studied for different temperature and different distance from the cathode arc source.The results show that the surface roughness of specimens is worsened in some degree.The effect of temperature and distance from the cathoed arc source is very obviously.更多还原
