QPQ surface treatment is a metal surface treatment technology, which is also known as “Quench-Polish-Quench”. This treatment process, involves placing black metal parts in two different salt baths with different properties. it allows multiple elements to penetrate the metal surface, formes a composite penetration layer.
The core of the QPQ treatment process, lies in its ability to improve the wear resistance, fatigue resistance, corrosion resistance. The treated workpieces have small deformation, which can replace multiple treatment processes and corrosion, by shorten processing time.
The main features of QPQ treatment:
1. Improve component performance: QPQ treatment can significantly improve the wear resistance, fatigue resistance, and corrosion resistance of components.
2. Reduce distortion: The distortion of the treated workpiece is small, make it suitable for the treatment of precision components.
3. Shorten time cycle: Comparing with traditional multi-stage heat treatment processes , QPQ treatment can greatly shorten the time cycle.
Comparison of QPQ treatment with other surface treatments:
1. Comparison with blackening treatment: QPQ treatment differs from blackening treatment in method. Blackening treatment is mainly for preventing metal from rusting, while QPQ treatment focus on improving the performance of components.
2. Comparison with nitriding treatment: QPQ treatment completes the whole process through “nitrogen-carbon-oxygen technology” in China. it differs from traditional nitriding treatment in specific operation. QPQ treatment forms a composite penetration layer, by introducing multiple elements, rather than just nitrogen.
When it comes to surface modifications, people often select QPQ treatment. It exists in various black metal components, especially suitable for industrial and mechanical parts, that require high wear resistance and high corrosion resistance.
In conclusion, QPQ surface treatment is an efficient, also as high-performance metal surface treatment. It is suitable for industrial and mechanical parts. QPQ technology has been widely applied in the automotive industry, with its good corrosion resistance, wear resistance, and anti-adhesion mechanical properties. Its application in the rolling balls and rollers of wind power bearing, and its solution to the problems of friction corrosion, fatigue failure, as well as the reduction of maintenance frequency.
