This coating can operate continuously in high-temperature environments below 800℃, demonstrating excellent resistance to high-temperature oxidation. In applications, DG.Ni20Cr is commonly used as a base coat for tungsten carbide or oxide ceramic coatings. It effectively enhances the adhesion between the coating and the substrate, alleviates stress generated in the ceramic layer during thermal cycling or under stress, and provides a good buffer and transition effect. Furthermore, this material is also suitable for the spraying of nickel-chromium targets, and has broad application value in surface engineering and remanufacturing.
