BLUE Surface Treatment
To enhance rust resistance and extend the service life of powder metallurgy products, BLUE offers the following surface treatment processes.
- Dacromet
Dacromet is a green and environmentally friendly surface treatment process that does not produce wastewater and exhaust gas and has high heat resistance and corrosion resistance. - Steam Treatment
Steam treatment can significantly improve the hardness, corrosion resistance and wear resistance of powder metallurgy products - Electroplating
There are gaps inside powder metallurgy products, so before electroplating, resin impregnation or copper infiltration is required to fill the pores. Common electroplating includes zinc plating, nickel plating.
What is a VVT Sprocket?
A variable valve timing (VVT) sprocket is a gear component mounted on the engine camshaft.
The working principle of the VVT sprocket is to adjust the amount of intake (exhaust) and the valve opening and closing time and angle by adjusting the camshaft rotation angle.
At low engine speeds (RPM), the VVT sprocket advances the timing to improve engine response and reduce fuel consumption.
At high engine speeds, it retards the timing to provide better power and prevent engine knock.
