Abstract

PURPOSE:To provide outer parts for a watch excellent both in function and appearance, by forming metal carbide coating on the surface of the elementary metal same as that which constitutes the carbide, or on the surface of an alloy contg. the metal. CONSTITUTION:A case made of a material contg., e.g., Fe, and Cr, Ni as principal components, is subjected to soln. heat-treatment to give desired hardness. After usual mirror finishing of the case 3 surface, the case is ocnnected to a cathode 2 of an ionization plating apparatus. The bell jar 1 is evacuated to the order of 10<-6> Torr, and Ar is introduced into the bell jar to 2X10<-2> Torr, then a voltage of 3 KV is applied by a voltage source 4, so that Ar bonbardment cleaning is performed, subsequently the bell jar 1 is evacuated to the order of 10<-7> Torr. Hereafter Ta 6 is evaporated by an electron beam evaporation source 5, simultaneously 200 V is applied from an ionization source to form Ta film on the surface of the case 3. Then C2H2 is introduced into the bell jar 1 to 4X10<-4> Torr to cause reactive ionization plating to form TaC film on the case 3 surface, thus outer parts for watch are prepared.
