Problems solved by technology

However, the problem of oxidation of the surface layer of the metal plate interface has not been solved, and the strength and performance of the finished composite metal plate are still insufficient. In addition, the process requires ultra-high pressure conditions and has high requirements for equipment, resulting in high costs.
[0009] Chinese invention patent CN201110029651.X discloses a method for preparing a stainless steel-carbon steel composite plate. This method introduces a composite blank between the plates, first welds and then rolls, and isolates oxygen, which significantly solves the problem of low interface strength caused by plate oxidation.
However, this method is only suitable for thick plates, and it is difficult to operate for thin plates. In addition, this method is not conducive to accurately controlling the thickness of the composite metal layer

Description

technical field [0001] The invention relates to the technical field of novel metal plate preparation, in particular to a plasma arc-enhanced ultrasonic metal composite plate preparation device and method. Background technique [0002] Due to its advantages of high strength and low cost, steel has become a metal material widely used in various fields. However, the corrosion resistance of steel is poor, especially in fields such as marine engineering, and its application is greatly limited. On the other hand, some corrosion-resistant metals and their alloys have good corrosion resistance, but the cost is relatively high. Therefore, corrosion-resistant and cost-effective metal composites have great potential and promising applications. [0003] Traditional metal clad plate preparation methods include explosive clad method and hot rolling clad method. [0004] Chinese invention patent CN201821521447.3 proposes a wide-width titanium-steel clad plate explosive composite structu...
