摘要： PURPOSE:To improve quality of a product and mold release characteristics by forming the surface layer of a molding die from substance consisting of at least two components of platinum and cobalt and also allowing nitride to be dispersed and incorporated in the components. CONSTITUTION:The surface layers 1b, 2b of molding dies 1, 2 are formed from substance which consists of at least two components, platinum (Pt) as a main component and about 5-45wt.% cobalt (Co). In this case, one or more kinds of nitrides selected from nitride such as AlN and TiN are dispersed and incorporated at a rate of about 0.02-30vol.% in the components of the surface layers 1b, 2b. Thereby denseness, hardness, strength and resistance to chemical reactivity of the surface layers 1b, 2b are improved and crystal growth in the structure is inhibited. Therefore, surface roughening based on the dies is prevented and precision of a molded face is stabilized while it is worked and therefore quality of a product and mold release characteristics of the dies are improved.
