    摘要: A press-molding die comprises a base material (1), an intermediate layer (2) formed on a surface of the base material and a protective layer (3) formed on the intermediate layer. The base material (1) comprises a silicon dioxide based glass or monocrystal alumina. The intermediate layer (2) comprises a material which adheres to both the base material and the protective layer and is heat resistant at high temperatures to which the die is subjected in. The protective layer (3) comprises at least one metal film selected from the group consisting of tungsten (W), platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir), osmium (Os), rhenium (Re), tantalum (Ta) and alloys thereof. Methods for manufacturing the die and use of the die for press-molding glass articles are also disclosed.

    摘要: A die for press-molding an optical element with high precision comprises a base material made of a material excellent in heat resistance, heat shock resistance and mechanical strength at high temperature, an intermediate layer formed on the base material and made of a thin film excellent in grinding machinability and cutting machin­ability, and a surface protective layer formed on the intermediate layer and made of a metal thin film excellent in heat resistance and mechanical strength at high temper­ature and less reactive to a material of the optical element. Additional thin film may be inserted between the base material and the intermediate layer so as to enhance the adhesion strength between the base material and the intermediate layer.
