Problems solved by technology

[0005] The common types of conductive films on the market today are mostly pure metal conductive films such as Ni, Cr, Cu, Pt, Au, Al or metal oxide conductive films such as ITO, AZO, SnO, etc., and their structures are metal oxide crystals or metal crystals. The structure, hardness and wear resistance are poor, and the color is single, which can no longer meet the needs of smart electronic devices
As a multi-component hard film, CrSiCN has good wear resistance and electrical conductivity. However, most CrSiCN coatings prepared by traditional PVD have a polycrystalline structure and a columnar morphology. Diffusion channel
In the field of smart wear, especially in the environment where the sensor is in contact with the skin for a long time, the conductive coating on the surface of the sensor will be in contact with corrosive substances such as sweat and chemical corrosion liquid (hand cream, alcohol) for a long time, and the corrosive particles will Diffusion to the substrate along the internal structural defects of the coating, especially the penetrating grain boundary from the coating surface to the substrate, causing the sensor to be corroded, thereby reducing its service life
