Preparation method of stainless steel-magnesium alloy composite plate

Abstract

The invention discloses a preparation method of a stainless steel-magnesium alloy composite plate, and belongs to the field of metal composite plate machining. The problem that the application of thestainless steel-magnesium alloy composite plate in the industrial field is restricted due to the fact that the stainless steel-magnesium alloy composite plate with good interface connection is difficult to form according to an existing forming method is solved. The preparation method adopts the structure of wrapping sealing, so that the problem of liable oxidation in the heating process of magnesium alloy can be effectively solved, and therefore, no additional inert gas needs to be applied for protection during the heating process. As a transition element, a silver coating on the surface to bebonded can improve the wettability of the magnesium alloy on the surface of stainless steel and promote the metallurgical bonding of the bonded surface. A hot pressing furnace is heated to a temperature higher than the melting point of the magnesium alloy, heat preservation and pressure maintaining are carried out for a period of time, so that the contact time between a magnesium alloy melt and the stainless steel surface is sufficient, and interface elements are more conducive to diffusing under the pressure. The prepared stainless steel-magnesium alloy composite plate has good bonding interface quality, high tensile strength and good corrosion resistance performance.

Description

technical field [0001] The invention belongs to the field of metal composite plate processing, and in particular relates to a preparation method of a stainless steel-magnesium alloy composite plate. Background technique [0002] With the development of the national economy and the emergence of various new technologies and new industries, the manufacturing industry continues to develop towards lightweight products. Compared with other structural materials, magnesium alloy has low density, high specific strength and specific stiffness, excellent electrical and thermal conductivity and damping performance, and also has great advantages in shock resistance and noise reduction, so it is increasingly popular in the industry, especially The attention of the automotive and electronics industries. However, the plastic formability of magnesium and magnesium alloys is poor. The fundamental reason is that the hexagonal close-packed structure of magnesium itself results in fewer slip sy...
