Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a corrosion-resistant composite metal material and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, people have put forward more requirements on the performance of materials, and metal composite materials have also emerged. Metal composite materials are composite materials that are artificially combined with metal and its alloys as the matrix and one or several metal or non-metallic reinforcements. The matrix materials include aluminum-based, iron-based, titanium-based, nickel-based, alloy-based, etc. , and aluminum matrix composites are widely used in the automotive and aviation fields because of their low density, good electrical conductivity and thermal conductivity. [0003] However, there are also defects in the use of aluminum matrix composites. For example, it is an extremely corrosi...
