本文报道了一种新型Pd基非晶合金作为具有衍射光栅的玻璃透镜成型模具的材料的应用。所要求的非晶态合金的性能如下：（a）非晶态合金必须能够在坯模上沉积成厚度大于50 μ m的膜;（B）当玻璃在空气中在非晶态合金的模上成型时，合金必须不表现出结晶或氧化，并且必须不粘附到玻璃上;（c）必须能够通过单点金刚石车削（SPDT）进行超精密加工（最大表面粗糙度Rz小于30 nm）;（d）必须具有大于0.6 GPa的断裂强度。我们采用了组合搜索，使用组合电弧等离子体沉积，以寻找满足上述标准的非晶合金。从Pt-Zr-Ni和Pt-Hf-Ni合金的组合搜索结果中筛选出Pt-Hf-Zr-Ni非晶合金。Pt 51 Hf 20 Zr 17 Ni 12合金满足上述所有标准，可以使用该合金通过SPDT制造成型模具，该成型模具能够成型具有衍射光栅的玻璃透镜。
This paper reports the use of a novel Pd-based amorphous alloy as a material for a glass lens molding die with diffraction gratings. The properties required of the amorphous alloy are as follows : (a) the amorphous alloy must be able to be deposited as a film with a thickness of more than 50 pm on a blank die ; (b) the alloy must not exhibit crystallization or oxidization and must not adhere to glass, when a glass molds on the die of the amorphous alloy in air ; (c) it must be able to ultra-precision machined (maximum surface roughness Rz of less than 30 nm) by single-point diamond turning (SPDT); (d) it must have a fracture strength of greater than 0.6 GPa. We employed a combinatorial search using combinatorial arc plasma deposition to search for an amorphous alloy that satisfied the above criteria. Pt-Hf-Zr-Ni amorphous alloy was selected from the results of the combinatorial search of Pt-Zr-Ni and Pt-Hf-Ni alloys. The Pt51Hf20Zr17Ni12 alloy satisfied all the above criteria and it was possible to fabricate a molding die by SPDT using it. The molding die was capable of molding a glass lens with diffraction gratings.
