Abstract

The invention provides a corrosion-resistant metal material, characterized in that a metal base material comprises a metal base material body, a multi-element composite co-permeation layer and a passivation layer from inside to outside, wherein the carbon content in the metal base material body is larger than or equal to 0.87 wt.%, the thickness of the co-permeation layer is 5-10 micrometers, and the thickness of the passivation layer is 2-5 micrometers. The multi-element composite co-permeation layer is obtained through a molten salt infiltration method (TD method), passivation is achieved by soaking in cerium salt and vanadium salt passivation liquid, the metal material has extremely high corrosion resistance, and the service life of the metal is effectively prolonged.

Description

technical field [0001] The invention relates to metal surface treatment technology, in particular to a corrosion-resistant metal material. Background technique [0002] The mold processes raw materials into products in a certain way through its own specific shape. The products produced in this way not only have high quality and high production efficiency, but also save raw materials and reduce costs. It has been widely used in many production industries such as glass and ceramic products. Therefore, molds play an increasingly important role in the entire modern industrial production, and now 60%-90% of industrial products need to use molds for processing. [0003] With the rapid development of mold processing technology, the requirements for mold materials are becoming more and more stringent. Now it is difficult to meet the requirements of mold strength, Hardness, wear resistance and corrosion resistance and other performance requirements, because in addition to brittle f...
