Abstract
A glass-shaping mold includes a steel base member, and a crystallized, machined layer, an intermediate layer and a mold-releasing layer which are sequentially formed on the base member. The machined layer is a layer of nickel alloy containing phosphorus. The intermediate layer is a layer formed of chromium, nickel, copper or cobalt. Alternatively, the intermediate layer is a layer of an alloy layer containing at least one of these elements. The mold-releasing layer is a layer of an alloy containing iridium and rhenium.
Claims4
A glass-shaping mold comprising a steel base member, and a crystallized, machined layer and a mold-releasing layer, which are sequentially formed on the base member,
- wherein the machined layer is a layer of a nickel alloy containing a phosphorus in concentration of 1 to 15% by mass, and the mold-releasing layer is a layer of nickel alloy containing iridium, rhenium and carbon, a carbon concentration being 1 to 50 at %.
A method of manufacturing a glass-shaping mold that comprises a steel base member, and a crystallized, machined layer and a mold-releasing layer which are sequentially formed on the base member, wherein the machined layer is formed on the base member and is then heated to be crystallized, and subsequently the mold-releasing layer is formed.
