Abstract

The invention discloses a steel/aluminum dissimilar metal element laser deposition additive manufacturing method, and aims to achieve integral additive manufacturing of a steel/aluminum dissimilar metal element from steel/aluminum dissimilar metal by using an additive manufacturing aluminum alloy process progressively in a one-step continuous formation manner or on a steel molded base body. According to the steel/aluminum dissimilar metal element laser deposition additive manufacturing method, the molded element has different components and properties at different parts by changing components, speeds and manufacturing process parameter conditions of conveying materials, furthermore integral design and manufacturing of material-structure-function can be achieved, and the steel/aluminum dissimilar metal element laser deposition additive manufacturing method has unique advantages of high efficiency, low cost, high performance quality and the like in the aspect of manufacturing dissimilar metal elements.

Description

technical field [0001] The invention belongs to the technical field of laser additive manufacturing, and in particular relates to a laser deposition additive manufacturing method for steel / aluminum heterogeneous metal parts. The method is especially suitable for laser additive manufacturing of steel / aluminum heterogeneous metal parts of various complex shapes. Background technique [0002] Steel and aluminum alloy are the two most widely used metal materials in modern industry. Steel / aluminum dissimilar metal composite structural parts can give full play to their respective advantages and performances. They have comprehensive advantages such as light weight, high strength, and corrosion resistance, and can reduce the overall design of parts. The manufacturing cost and the realization of the structural and functional integration of parts have received more and more attention. For example, the valves and ducts of rocket engines, the body frame of automobiles, and the superstru...
