PURPOSE:To obtain a vessel having superior consumption resistance and a long life by cladding the surface of an Mo-base metal with a Pt-base metal. CONSTITUTION:When an Mo or Mo alloy vessel is used as a crubible for melting glass or ore contg. metallic oxide at a high temp. or as a tray, a boat or the like for vacuum deposition, oxide is formed by a reaction with O2 in the air. Since this oxide is liable to evaporate, the vessel is required to be used in an inert atmosphere. Even though the vessel is used in such a way, when glass, ore or the like contg. metallic oxide is melted, O contained in the resulting melt bonds to Mo to shorten the life of the vessel. The surface of the vessel is clad with Pt or a Pt alloy by physical vapor deposition such as ion plating so as to obtain a vessel having superior oxidation resistance and a long life. |
