Thermal dusting is a technique that extends the life of a product by protecting it from volatile environments. There are various thermal spray powders and various application processes on the market, such as tungsten carbide spray technology, which belongs to thermal spray technology. The following thermal spray manufacturers will show you some different thermal spray powders.
Anti-corrosion thermal spray
When it comes to metallic coatings, there are two basic categories: engineering coatings and finishing coatings.
Engineered coatings can refer to barrier coatings or wear-resistant coatings such as tungsten carbide coatings. Finish coatings can refer to decorative or anti-corrosion coatings. For example, the metal spray engineering and corrosion protection market can include the construction, petrochemical, marine, and oil and gas industries.
How is metal thermal spraying performed?
Small molten particles are projected onto the surface in a continuous coating and adhere to the surface. That's it in a nutshell. Of course, in actual work, it is far more complicated than the above understatement, but this is a basic working idea, which also involves atomization methods, spraying materials and heat source technology.
mineral powder
Various industries will use different kinds of coating materials. Here are some commonly used powder metals:
Tungsten carbide powder, zinc powder, tin powder, black and red copper oxide, nickel powder, manganese powder, iron powder, granular copper, cadmium oxide powder, bismuth powder, aluminum powder, etc. When it comes to the application of these spray powders, there is a wide range of different particle size distributions.
Not all thermal spray uses metal powders, and while the thermal spray process is often associated with metal powder spraying, the application of non-metallic materials may be involved. Plastics, ceramics, alloys and composites can also be thermally sprayed onto surfaces.
Increased particle velocity generally equates to increased coating quality. Many measurements are used to evaluate coating quality. Including surface roughness, bond strength, micro and macro hardness, oxide content and porosity.
Technology similar to thermal spray
In addition to the various substances that can be thermally sprayed, there are many thermal spray variants. These include the following:
Cold spray, warm spray, HVAF or air fuel, HVOF or oxy-fuel spray, flame spray, wire arc spray, detonation spray, plasma spray.
Industries using Thermal Spray Coatings
In fact, the application of thermal spray technology is very extensive, maybe more widely than you think. It has penetrated into every aspect of our lives. Let's list some industries that use thermal spray:
Wire drawing, wind energy, valves, textile manufacturing, solar energy, rubber manufacturing, pump maintenance, pulp and paper, printing machinery, power and energy, pharmaceutical and petrochemical, tooling, mining, metal production processing, material handling, marine, industrial machinery, food and Beverage processing, fluid handling, electronics and semiconductors, defense and military, converting, compressors, chemicals, bottling and canning, biomedical, automotive, agriculture, aerospace and gyroplanes.
