With the rapid development of modern industry, the application of surface treatment technology is more and more extensive. This is mainly due to the fact that many components have suffered various degrees of damage in harsh environments, such as parts that operate under high temperature, high pressure, corrosion, heavy load, and operation. Destruction often starts from the surface, and local damage may cause failure of the part or even the shutdown of the equipment. Effectively extending the life of the material, conserving resources, providing efficient productivity, reducing pollution, and even imparting new and stronger functions to the material through modification can be an advantage of surface treatment technology. It can use a variety of methods to produce a new functional film superior to the material itself, so that it has higher wear resistance, corrosion resistance, high temperature resistance than the bulk material, and even has functions that it does not have or ability. At the same time, surface treatment technology can also be used to locally strengthen and protect the surface of the material in order to achieve the purpose of prolonging the service life or returning to the original use value.
At present, the modification of PTFE film mainly adopts the principle of compounding, so that it can be combined with other materials to make up for its own defects. The modification methods mainly include: filling modification, surface modification, blending modification and the like. Electroless plating can form a uniform metal coating on the surface of the material, which not only improves the various properties of the substrate, but also provides good protection and new properties.
Electroless nickel-plated alloy coatings have been widely used due to their high hardness, good wear resistance and excellent corrosion resistance. Nickel plating can be applied not only to decoration but also to functional coatings. The electroless plating technology of non-metallic materials is a means of connecting metal and non-metal materials, and it will inevitably be more widely studied and applied in the rapid development of new functional materials. Electroless nickel plating is used to deposit a metal or metal alloy coating on the surface of the PTFE film to improve the overall performance of the PTFE film and expand the application field of the fluorine-containing material.
