Description

technical field [0001] The invention belongs to the technical field of alloy coating materials, and in particular relates to a preparation method of an amorphous hard coating with adjustable long-life color and transparency. Background technique [0002] Amorphous metal coatings have excellent properties such as high strength, high hardness, high wear resistance, high fracture toughness, excellent corrosion resistance and high surface finish. Therefore, composite materials containing amorphous metal coatings can not only greatly Improve the intrinsic mechanical properties and corrosion resistance of the matrix material such as strength, hardness and wear resistance, prolong the service life of the matrix, and improve the surface quality of the matrix material. [0003] Chinese patent CN103065789B discloses a preparation and coating method of a high-performance iron-based amorphous metal powder core. The iron-based amorphous material is crushed into powder by ball milling, pa...
