Abstract

A coated article is described. The coated article includes a stainless steel substrate, a bonding layer formed on the substrate, and a hard layer formed on the bonding layer. The bonding layer is a nickel-chromium alloy layer. The hard layer is a nickel-chromium-boron-carbon-nitrogen layer. The mass percentages of carbon and nitrogen within the hard layer are gradually increased from the area near the bonding layer to the area away from the bonding layer. A method for making the coated article is also described.
