Paper Title:
Lead-Free Oxidation- Resistant Glass-Ceramic Coating for Heat Processing of Ti-6Al-4V Alloy
  Abstract

Now the oxidation-resistant glass-ceramic coatings have been widely used in reducing surface oxidation of Ti alloys during heat process. In present investigation, a lead-free glass-ceramic coating with wider protection temperature range was developed to protect Ti-6Al-4V alloy from oxidation. The phase compositions of the present coating and the oxygen distributions in the surface layers of Ti-6Al-4V specimens were investigated by means of XRD, as well as the metallographs of cross-section were observed and the depths of oxidized layers were determined by microhardness analysis. The results show that the present glass-ceramic coating can provide the oxidation-resistant effect over the temperature range of 500-1000oC in ambient air, with an environmentally friendly lead-free coating composition.
