After the Beijing Institute of Mining and Metallurgy developed a "composite nickel-aluminum coating material coated with nano-aluminum powder," it successfully developed a "composite series coating material coated with nano-aluminum powder." This series of coating materials includes two-component intermediate compounds such as nickel aluminum, three-component compounds nickel-chromium aluminum, multi-component compounds nickel chromium aluminum cobalt oxide niobium, iron chromium nickel aluminum tungsten carbide wear resistance, corrosion resistance and high temperature resistant surface Layers and materials at the bottom layer have significantly better performance than similar foreign products, but their costs are significantly reduced. They have been successfully used in many key models of military industries and civil coating materials for large equipment such as petrochemicals, boilers, metallurgy, papermaking, and transportation. , With significant social and economic benefits.
