Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and in particular relates to a corrosion-resistant composite metal material and a preparation method thereof. Background technique [0002] Alloys are substances with metallic properties that are synthesized by two or more metals and metals or nonmetals by a certain method. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multi-element alloys. Corrosion-resistant basic alloying elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for corrosion-resistant structures and properties. As the environment is getting worse and worse, there are more and more pollutants in the air and rainwater, and the corrosion of materials is becoming stronger and stronger. Ordinary metal matrix com...
