The oxidation is a serious problem during the heat process of Ti alloys in air.Now the oxidation-resistant glass-ceramic coatings have been widely used in reducing surface oxidation of Ti alloys during heat process.Unfortunately,conventional oxidation-resistant coatings only can provide a relatively narrow protection temperature range,and usually contain a considerable amount of lead,which is environmentally harmful.So in present investigation,a lead-free glass-ceramic coating with wider protection temperature range was developed to protect Ti-6Al-4V alloy from oxidation via a common dip-coating and sintering route.
