Abstract: The invention relates to a coating for preventing intermetallic bonding, in particular to a water-based high-temperature-resistant titanium-steel anti-bonding coating and its use in the preparation process of titanium ingot. The water-based high-temperature-resistant titanium-steel anti-bonding coating of the invention includes the following components in parts by weight: 50-150 parts of water-based film-forming agent, 0-50 parts of Zn powder, 400-450 parts of Al2O3 powder, and 250-350 parts of talcum powder. The coating of the invention can avoid the bonding reaction with a roller or a winch of the steel equipment in the rolling or perforation process of a titanium tube at 900° C., so as to improve the yield and the production efficiency of titanium material processing. Moreover, the process is simple and easy to operate, the coating is environment-friendly and pollution-free, and easy to prepare.
