Ti-based alloy ingots are susceptible to suffering with high temperature oxidation during heat treatment and cracking during forging. So glass-based coatings are used to protect the Ti-based ingots. It can simultaneously increase the oxidation resistance of the ingots and make a positive effect on lubrication during forging. Moreover,the glassbased coating can make a thermal insulation effect due to its low thermal conductivity,which is also beneficial for forging. In this investigation,the development status of the glass-based coatings for Ti-based alloy ingots,including the designing principle,chemical composition,preparation method,mechanisms of high temperature protection and lubrication,interfacial reactions between the coating and the substrate were reviewed. Furthermore,the development direction of the glass-based coating for Ti-based alloy ingots was discussed as well.
