Abstract

PURPOSE:To improve the corrosion resistance of titled cermet obtd. by incorporating Ni and/or Mo as a bond phase into the cermet contg. the carbide, etc., of Ti as a hard phase and adding Cr thereto. CONSTITUTION:The cermet which contains >=1 kinds of the carbide, nitride and carbonitride of Ti as the hard phase and contains 18-45% Ni and/or Mo and 3-13% Cr is prepd. The cermet contains further preferably the elements of group IV, V or VI of the periodic table or the carbide, nitride or carbonitride of said elements. Cr is solutionized in the bond phase by this constitution, by which the potential difference between the hard phase and the bond phase is decreased and since the passive state of Cr is further formed, the elution of the metal is suppressed and the corrosion resistance of this cermet is improved. This cermet is, therefore, adequate as a frame of a wrist watch for which the high corrosion resistance is demanded.
