Abstract

PURPOSE:To provide a white exterior parts excellent in corrosion resistance, flaw resistance, and wear resistance, which has an inexpensive, beautiful noble-metal- like tone, by forming the first layer cont. one or more members selected from the group consisting of Ti, Cr, Ni, Co, Zr, V, and the second layer of a prescribed thickness contg. one or more members of platinum group metals on a heat resistant substrate. CONSTITUTION:A vacuum tank 1 is evacuated 2 to 5X10<-3>Torr, and is maintained at 5X10<-2>Torr by introduction 3 of Ar gas. Then the vacuum tank is maintained at 3X10<-3>Torr after introduction 3 of a mixed gas of Ar with N2. In the tank 1, Ti 8 is evaporated by the regulation of a power source 9 to form white coating contg. Ti and N as principal components on the heat resistant substrate 4 such as stainless steel etc. Subsequently, platinum group metal 11 such as platinum is evaporated from a crucible 10 by the regulation of the power source 9 to form the second layer 100-10,000Angstrom in thickness on the base material 4. A watch case is an example of the substrate 4.
