Diversity and application of thermal spray coating

       Thermal spray manufacturers introduce the diversity of thermal spray coating properties



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



2. Sprayable coating materials are very common, and thermal spraying technology can be used to spray solids, such as cemented carbide, ceramics, metals, graphite, etc.;



3. The temperature rise of the substrate material is small during the spraying process, and no stress and deformation are generated;



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



5. The thickness of the coating can be from 0.01 to several millimeters;



6. The coating has various properties, and can form coatings with various special functions such as wear resistance, corrosion resistance, heat insulation, oxidation resistance, insulation, electrical conductivity, and radiation protection;

7. It has the advantages of strong adaptability and good economic benefits.

Analysis on the application of thermal spraying special coating technology



Thermal spraying characteristics: Using plasma spraying and explosive spraying technology, special ceramic coatings are sprayed on the surface of plungers and piston rods in various hydraulic cylinders and reciprocating pumps.







The outstanding features are:



1. The ceramic coating and the steel matrix form a composite material structure, which effectively uses the advantages of thermal spraying, with high strength and wear resistance and corrosion resistance;



2. Low friction coefficient, low energy consumption, reduce friction energy consumption;



3. Small wear on sealing packing or paired parts, reducing maintenance;



4. The service life is 3 to 6 times longer than that of chrome-plated parts, which is an environmentally friendly coating technology.







Application: This thermal spraying technology is widely used in reciprocating pump plungers, hydraulic cylinder piston rods, etc.
