Problems solved by technology

Due to the significant difference in the interface properties between the coated polymer and the surface of the metal material, the use of mechanical coating methods cannot overcome the mechanical properties and wear resistance of the materials on the joint surface between the metal material surface and the coating material. There are large differences in gradients. In addition, there are defects such as defects, bubbles, and insufficient mechanical bonding between the interfaces, so that although the surface of the metal material treated by the mechanical coating method has enhanced corrosion resistance, it obviously shows low microhardness. Defects such as resistance to friction and wear, weak interface bonding force, etc., resulting in reduced service life

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a metal material surface treatment process. Background technique [0002] Metal materials will be subjected to various loads in the actual application process, and this long-term load will lead to their failure. Failure usually occurs on its surface, therefore, surface strengthening is an important means to prolong its service life. In order to enhance the mechanical properties and corrosion resistance of the surface of metal materials, coating polymer coatings on the surface of metal materials is one of the common means. Due to the significant difference in the interface properties between the coated polymer and the surface of the metal material, the use of mechanical coating methods cannot overcome the mechanical properties and wear resistance of the materials on the joint surface between the metal material surface and the coating material. There are large differences...
