Method for manufacturing magnesium alloy-stainless steel composite board

Abstract

The invention discloses a method for manufacturing a magnesium alloy-stainless steel composite board, which belongs to the field of metal composite board processing and aims to solve the problem thatapplication, in the industrial field, of the magnesium alloy-stainless steel composite board with relatively good interface connection, which is difficulty formed by an existing forming method, is restrained. A packaging and sealing structure can be adopted to effectively solve the problem that oxidization is easily caused in a magnesium alloy heating process, so that inert gas does not need to additionally apply in a heating process for protection; a silver-coated layer of a to-be-combined surface can be taken as a transition element to improve wettability, on a stainless steel surface, of amagnesium alloy, so that metallurgical bonding of the combined surface is promoted; the temperature of a heating furnace exceeds a melting point of the magnesium alloy, and the magnesium alloy is quickly discharged out of the furnace for being quickly cooled after heat is preserved, so that magnesium alloy melt has sufficient contact time with the stainless steel surface, and therefore, diffusionof the interface element is facilitated; besides, the packaging sealing structure further can prevent the magnesium alloy melt from being heated to expand, so that pressure does not need to additionally apply through the method, relatively great stress is generated on the combined interface, and diffusion connection of the combined interface is promoted.
