Abstract
A coated article and method for manufacturing the same wherein an alloy substrate of iron, nickel, cobalt, or titanium base has a diffusion layer formed thereon of an intermetallic boride of the substrate alloy. A coating is subsequently deposited on the diffusion layer, which coating is a refractory, ceramic or intermetallic compound having desired wear and/or corrosion resistant properties superior to those of the substrate.
Claims27
A coated article comprising an alloy substrate of an alloy selected from the group consisting of iron, nickel, cobalt and titanium base alloys, a diffusion layer formed thereon comprising an intermetallic boride of the substrate alloy, a coating on said layer of a material selected from the group consisting of refractory, ceramic and intermetallic compounds having desired wear and/or corrosion resistent properties superior to those of said alloy substrate.
A coated article comprising an alloy substrate of an iron-base alloy, a diffusion layer formed thereon comprising an intermetallic boride of the substrate alloy, a coating on said layer of a material selected from the group consisting of refractory, ceramic and intermetallic compounds having desired wear and/or corrosion resistant properties superior to those of said alloy substrate.
A coated article comprising an alloy substrate of a nickel-base alloy, a diffusion layer formed thereon comprising an intermetallic boride of the substrate alloy, a coating on said layer of a material selected from the group consisting of refractory, ceramic and intermetallic compounds having desired wear and/or corrosion resistant properties superior to those of said alloy substrate.
A coated article comprising an alloy substrate of a cobalt-base alloy, a diffusion layer formed thereon comprising an intermetallic boride of the substrate alloy;
- a coating on said layer of a material selected from the group consisting of refractory, ceramic and intermetallic compounds having desired wear and/or corrosion resistant properties superior to those of said alloy substrate.
A coated article comprising a titanimum base alloy substrate, a diffusion layer formed thereon comprising an intermetallic titanium boride compound, a coating on said layer of a material selected from the group consisting of refractory, ceramic and intermetallic compounds having desired errosion and abrasion-resistant properties superior to those of said substrate.
