Description

QPQ Salt Bath Nitriding QPQ composite processing technology

After 10 years of experimental research, CAEC successful developed the second generation of QPQ technology - deep QPQ technology. The thickness of compound layer was increased from the original 15 ~ 20 microns to more than 30 ~ 40 microns. Picture 1 shows Metallographic photos for Deep QPQ treatment and general QPQ technology treatment

It has been proved by abrasion resistance test, corrosion test, mechanical property test and permeability layer microstructure test that component compound layer thickness is multiplied and work piece’s various performances are greatly improved after second generation QPQ treatment.

Wear resistance: sliding wear after deep QPQ treatment on 45 steel demonstrate that wear resistance is four times that of ordinary QPQ treatment. Work-piece rolling wear experiment shows similar results.

Corrosion resistance: after deep QPQ treatment of 45 steel corrosion resistance of weightlessness experiment is 12 times increase compared to traditional QPQ treatment.

Corrosion resistance is more than 1 times higher. If combined with sealant, the corrosion resistance of salt spray test can reach more than 300 h or even higher.

Impact toughness: impact toughness after deep QPQ treatment on 45 steel is 1.98 times higher than ordinary QPQ treatment.
