Bluing process
In order to reduce the production cost and improve the protective performance, the blueing process came into beingMoreover, it has started to be applied in large quantities in the field of air conditioning compressor.
- ① 50% cost down compares with phosphate treatment；
- ② Excellent heat resistance (120℃,100%RH,2atm,≥96h)；
- ③ Production process safety and environmental protection.
| After 96h PCT Test | ||
|---|---|---|
| Process | Surface Changes | PCT Resistance |
| Bluing | No significant changes | Bluing process is better than phosphating |
| Phosphating | Phosphate film is peeling | |
