The invention discloses a metal anti-corrosion coating for a pressure container with high salt content and wet hydrogen sulfide working condition and a preparation method of the metal anti-corrosion coating. The anti-corrosion coating comprises metal powder, including 78-84% of Ni, 15-17% of Cr, 0-0.5% of W, 0.8-1% of Mo, 0-0.1% of C, 0-0.01% of S, 0-0.01% of P and 2.0-3.5% of B and Si. The metal anti-corrosion coating has the benefits that the requirements of induction brazing filler metal remelting on self-melting nature of a material are met, the metal anti-corrosion coating of the pressure container can be prepared by using a novel spraying process of hot spraying and induction brazing filler metal remelting, the corrosion requirements of an environment with high salt content, wet hydrogen sulfide and wet natural gas are met, the binding strength of the coating with a substrate is greatly improved, and the porosity of the coating is reduced, so that the metal anti-corrosion coating ...
