What is the main use of thermal spray technology in equipment maintenance

Thermal spraying technology is a method that uses a heat source to heat the sprayed material to a melted or semi-dissolved state, and sprays and deposits it on the surface of the pretreated substrate at a certain speed to form a coating. Thermal spraying technology on the surface of ordinary materials, to create a special working surface, so that it can achieve: anti-corrosion, wear resistance, anti-friction, high temperature resistance, anti-oxidation, heat insulation, insulation, conduction, anti-microwave radiation and other functions, so that it can achieve the purpose of saving materials and energy.

Thermal spraying technology is one of the important components of surface process technology, accounting for about one-third of surface engineering technology.

1) Prepare new parts and use arc spraying and plasma technologies to manufacture mechanical parts. 2) Material modification, using thermal spraying technology to treat ordinary materials, can change the chemical composition and microstructure of its surface as needed.

To achieve the purpose of strengthening some properties of the surface. 3) Repair of old parts, thermal spraying technology can not only restore the size of the parts, but also strengthen the performance of the surface of the parts. 4) Prepare specific functional layers, such as wear-resistant coatings, corrosion-resistant coatings, high-temperature resistant coatings, shielding coatings.

Increase the anti-corrosion, wear-resistant, high-temperature resistance, oxidation resistance and other properties of the equipment, and choose different spraying materials according to the needs to spray a layer of ceramics on the surface of the lifting roller and conveying roller by thermal spraying, so as to improve the pair of lifting roller and conveying roller.

Dimensional reduction of wear and corrosive parts.

Thermal spraying refers to the use of "oxygen-ethyl" alkyne flame, arc, plasma arc, ** wave and other spraying devices to provide different heat sources, generating high temperature and high pressure flame flow or supersonic flame flow, the materials to be made into coatings, such as various metals, ceramics, metal and ceramic composite materials, various plastic powder solid spraying materials, instantaneously heated to a plastic or molten state, high-speed spraying to the surface of pretreated (clean rough) parts to form a coating. We call the special working surface "coating", and the working method of manufacturing the coating is called "thermal spraying", which is a general term for spraying and spray welding using various heat sources.

Thermal spraying is a kind of surface strengthening technology, which is an important part of surface engineering technology, and has always been a new technology project promoted in China. It is a technology that uses a certain heat source (such as electric arc, plasma arc or combustion flame) to heat powdered or filamentous metal or non-metallic materials to a molten or semi-molten state, and then spray them to the surface of the pretreated substrate at a certain speed with the help of the flame retention itself or compressed air to form a surface coating with various functions.

It is the use of a certain heat source (such as arc, isoplasm and finch spraying or burning flame, etc.) to heat powdered or filamentous metal or non-golden-skinned loose materials to a molten or semi-molten state, and then with the help of flame retention itself or compressed air sprayed to the surface of the pretreated substrate at a certain speed, deposited to form a surface coating with various functions. But the combination is not very good.

There are many technical characteristics of thermal spraying, which are briefly listed with you below.

1. The base material is not restricted, it can be metal and non-metal, and can be sprayed on various base materials;

2. The coating materials that can be sprayed are extremely extensive, and the thermal spraying technology can be used to spray almost all solid engineering materials, such as cemented carbide, ceramics, metals, graphite, etc.;

3. The temperature rise of the matrix material is small during the spraying process, and there is no stress and deformation;

4. The operation process is flexible and convenient, not limited by the shape of the workpiece, and the construction is convenient;

5. The coating thickness can be from a few millimeters or a dozen millimeters;

6. The coating has a variety of properties, which can form a coating with various special functions such as wear resistance, corrosion resistance, heat insulation, oxidation resistance, insulation, electrical conductivity, radiation protection, etc.;

7. Strong adaptability and good economic benefits.

1. The equipment is light and can be constructed on site.

2. The process is flexible and the operation procedures are few. It can be repaired quickly and reduces processing time.

3. Strong adaptability, generally not limited by the size of the workpiece and the site.

4. The thickness of the coating can be controlled.

5. In addition to spray welding, the heating temperature of the substrate is low, the deformation of the workpiece is small, and the metallographic structure and performance changes are also small.

6. It is suitable for parts of various matrix materials, and various protective coatings and functional coatings can be prepared on almost all solid material surfaces. From the analysis of the principle and process of thermal spraying technology, thermal spraying technology has the following characteristics.

Due to the wide temperature range of the heat source, the coating materials that can be sprayed include almost all solid engineering materials, such as metals, alloys, ceramics, cermets, plastics, and the compounds composed of them. Therefore, it can give the substrate a surface with various functions (such as abrasion resistance, corrosion resistance, high temperature resistance, oxidation resistance, insulation, heat insulation, biocompatibility, infrared absorption, etc.).

The degree of heating on the surface of the substrate during the spraying process is small and controllable, so it can be sprayed on various materials (such as metal, ceramic, glass, cloth, paper, plastic, etc.), and has almost no effect on the structure and properties of the substrate, and the workpiece deformation is also small.

The equipment is simple and flexible in operation, which can not only spray large components in a large area, but also spray in a specified area; It can be sprayed indoors in the factory or applied outdoors on site.

There are fewer procedures for spraying operations, shorter construction time, high efficiency, and more economical. With the improvement of thermal spraying application requirements and the expansion of the field, especially the progress of spraying technology itself, such as the increasing high energy and sophistication of spraying equipment, the gradual increase of coating material varieties, and the gradual improvement of performance, thermal spraying technology has achieved rapid development in the past ten years, not only the application field has been greatly expanded, but also the technology has developed from the early preparation of general protective coatings to the preparation of various functional coatings; From the maintenance of a single workpiece to the manufacture of a large number of products; From a single coating preparation to a coating system engineering including product failure analysis, surface pretreatment, development and selection of coating materials and equipment, coating system design and post-coating processing; It has become a very active discipline in the field of material surface science. And in modern industry, independent material processing technologies such as casting, forging, welding and heat treatment are gradually formed.

It has become an important technological means for the industrial sector to save precious materials, save energy, improve product quality, extend product service life, reduce costs and improve work efficiency, and has been more and more widely used in various fields of the national economy.
