WST surface treatment
Welltest Special Technology
The official name of the technology is "WST Treatment" or "WST Surface Lubrication Treatment"
WST surface lubrication treatment
Using a new method of combining thermal spraying and beading technology, the sprayed material is impacted on the substrate at high temperature and high pressure, so that the structure of the substrate surface within 20um is recrystallized and the grain boundary is precise, and solid lubricant is added to the process The metal surface structure contains solid lubricant to achieve the metal's strong and lubricating properties.
Effect of WST treatment
Improve sliding performance / improve oil film adhesion / reduce wear / extend life
Improve surface hardness/fatigue strength
After WST treatment, the surface structure changes and the microcracks disappear.
Fatigue strength and surface hardness also increase
