Thermal spraying is a technology that utilizes heat sources such as electric arc, plasma spraying and flame. In this design scheme, the volume of mass is analyzed, the powder or filamentous metal or non-metallic material is heated to the molten or semi-molten state, and then the flame itself or compressed air is sprayed on the surface of the pretreated substrate at a certain speed, and the multifunctional surface coating is formed by deposition.

Whether mechanical parts or metal components, the most prominent problem is surface wear or corrosion or both. Here is a brief introduction of the coating application guide: 1. Wear resistance - the largest application field of thermal spraying technology at high and low temperatures. This kind of coating is divided into the following types:

Diamond-like carbon coating, abbreviated as DLC coating, is an amorphous hard carbon thin-film material. Featuring a special mixed carbon-bond structure, it combines the high hardness of diamond and the low-friction property of graphite, making it a new-type coating material with excellent comprehensive performance in the field of industrial surface modification. Unlike the single structure of traditional cermet coatings, DLC coating consists of a mixture of sp³ and sp² carbon bonds without regular crystal arrangement. This unique microstructure overcomes the drawbacks of natural diamond such as high

Flame spraying is one of the common spraying processes used by thermal spraying manufacturers. Generally, flame spraying can be used for metallic and non-metallic substrates. Flame spraying is generally not limited by the shape and size of the substrate, and the coating materials are also very wide. Metal, alloy, ceramic and composite materials can be used as coating materials to make the substrate surface have the functions of corrosion resistance, wear resistance, high temperature resistance and heat insulation.

With the continuous advancement of industrial surface modification technologies, a wide range of hard coatings and protective coatings have emerged. These coatings differ greatly in performance focus and applicable scenarios. Featuring balanced performance, broad adaptability and strong compatibility with diverse working conditions, chromium nitride coating serves as an excellent upgraded alternative to traditional coatings and is widely adopted for
