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