Application of low-nitrogen alloy coating, Cr-Zr-N alloy material and hard corrosion-resistant coating and preparation method of low-nitrogen alloy coating, Cr-Zr-N alloy material and hard corrosion-resistant coating

Abstract

The invention relates to application and preparation methods of a low-nitrogen alloy coating, a Cr-Zr-N alloy material and a hard corrosion-resistant coating. The alloy coating comprises a Cr-Zr-N alloy material and mainly comprises three elements of Cr, Zr and N, the Cr, the Zr and the N have a specific relative atomic ratio (CrxZryNz), x is larger than or equal to 41.3 and smaller than or equal to 61.4, y is larger than or equal to 33.2 and smaller than or equal to 40.0, and z is larger than or equal to 5.4 and smaller than or equal to 25.5. The alloy coating has low-nitrogen design, has high hardness and excellent corrosion resistance by optimizing the proportion of the three elements, and can be used as at least one part of a hard corrosion-resistant coating in a coated product.
