Basic properties and manufacturing process of thermal spraying powder.
1 Aluminum based powders
* Used for corrosion protection coating
* Good for repair of Al based parts
* Good for electrical conductivity
2 Cobalt based poeders
* Excellent oxidation resistance
* Replaces Tungsten carbide coating in high tem[erature application
*Suited for repair of Co based for repair of Co based parts
* Dense coating with low porosity and oxide content
* Machining performance
3 Iron based powders
* Excellent oxidation resistance
* Smooth coating which is easy to machining
* Good again fretting, cavitation, and erosion
* Used for dimension repair and build-up
4 Nickel based powders
* Good corrosion and oxidation properties
* Coating are dense and moderatery hard, easy to machine
* Good for repair of Ni Based and SS parts
* Can be used for a ceramic bond coat

As mentioned at the beginning, the correct selection of powder is the key to successful coating application. However, the selection of powder is indeed a very complex process. Without enough experience and theoretical basis, it is difficult to choose a very suitable powder. The factors we should consider include but are not limited to:
*The manufacturing level of powder suppliers;
*Powder manufacturing process, mechanical crushing, sintering, atomization and agglomeration, etc;
*Characteristics of spray gun, such as sg100 spray gun of Praxair and F4 spray gun of Metco.
*In practical application, the spraying powder parameters need to be adjusted according to the characteristics of spray gun; Size, material and other characteristics of the workpiece.

APT does not produce powder, but the experience accumulated in coating application for a long time enables us to find suitable powder among many factors and obtain successful coating application.

Therefore, whether you need us to spray coating for your parts, recommend a suitable powder for you, or provide an overall coating solution for your parts, you can contact us immediately.
