New technology for surface coating of metal components: Hangzhou Juxing Technology Co., Ltd. has applied for a patent for "Metal Component Surface Coating Method", which forms a base layer by electroplating first, and then forms a surface layer by plasma magnetron sputtering coating on it, increasing the bonding force between the base layer and the surface layer on the metal surface. Due to the high hardness and good wear resistance of the sputtering coating, the protective layer on the entire metal surface is not easily peeled off.

Chemical plating technology: It is a plating method that uses a suitable reducing agent to reduce metal ions in the plating solution to metal and deposit them on the surface of the part without external current. It has the characteristics of uniform coating, small pinholes, and the ability to deposit on non-conductive surfaces. It has low waste discharge, minimal environmental pollution, and low cost, and is widely used in industries such as electronics and machinery. For example, electroless nickel phosphorus alloy coating has high hardness, strong wear resistance and corrosion resistance, smooth surface, and can be used to coat complex shaped workpieces, with a wide range of plated materials.

Combination technology of femtosecond laser element doping and cyclic low temperature annealing: the scientific researchers of Chunguang Institute, President of Chinese Science, use this technology to build a bionic ant cave like structure on the surface of metal aluminum alloy, achieve efficient and stable self starting superhydrophobic effect, create a metal surface that can maintain superhydrophobic performance without organic coating, and have broad application prospects in self-cleaning, anti-corrosion, drag reduction, ice prevention and other fields.

Graphene metal boundary film agent technology: Graphene metal boundary film agent developed by Qingdao Greyne Metal Protection Technology Co., Ltd. can replace processes such as chromating, phosphating and chromium free passivation that pollute the environment. The raw material is environment-friendly phytic acid, supplemented by modified graphene nano additives. After simple immersion or spraying process, it can form phytic acid based self-assembled corrosion inhibition boundary facial mask on the surface of various steels, improving corrosion resistance and enhancing film adhesion.
