Abstract

PURPOSE:To form an erosion-resistant hardened film which is dense and is hard to peel without transformation of the material to be treated and deterioration of material characteristics by carrying out heating and hardening treament for titanium materials in the powder of magnesium oxide or aluminum oxide under specified temperatures. CONSTITUTION:A titanium material is buried in the powder of magnesium oxide or aluminum oxide, and is heated a 550-850 deg.C in the atmosphere. Then, magnesium oxide or aluminum oxide does not react with the titanium material, and the oxygen and nitrogen in air are supplied sufficiently to the titanium surface, whereby stable titanium oxide is formed. Below 550 deg.C heating temp., the dense hardened film of erosion resistance is unotainable, and if it exceeds 850 deg.C, the film layer is embrittle and the transformation of the base material is caused, resulting in the degraded material characteristics.
