Abstract
PURPOSE:To obtain an optical mirror which has superior reflectivity, corrosion resistance, oxidation resistance, and heat resistance, and high strength by finishing the surface of a specular body material, which is cured with deposition texture and made of an Ni base alloy containing Cr and Al, into a specular surface. CONSTITUTION:The surface of a specular body material which is cured with deposition texture and made of an Ni base alloy containing 30-45wt% Cr and 2.5-5wt% Al is polished and finished into a specular surface. Through an aging treatment, said Cr-Al-Ni alloy is cured with deposition texture while the alpha phase, gamma phase, and gamma' phase are compounded, so high strength and superior characteristics are obtained. The Ni component in said alloy contributes to the improvement of the toughness and also keeps the corrosion resistance. The Cr component contributes the corrosion resistance as well as the Ni component and also accelerates the deposition of the alpha phase by grain boundary reaction. Further, the Al component is a produced element of a gamma'-Ni3Al phase and contributes the acceleration of the compound deposition of said alpha phase, etc., to improve aging curing characteristics greatly.
