Evaluation of internal stresses in modified near-surface layer of 20kh13 steel during incubation period of water droplet impact erosion

HIGHLIGHTS

SUMMARY

    The lowest stress of 2.1 GPa in the near-surface layer was observed in 20Kh13 samples with nitriding type II, and the highest stress of 3.4 GPa was Stress Value σ, GPa observed in 20Kh13 samples without modification or coating. For 20Kh13 samples without surface Modification 10 min 195 min 600the minincrease modification and 20Kh13 with coating in the stage from 195 min to 600 min of stresses is significant stage from 10 to 195 The lowest stress of 2.1 GPa in the near-surface layer was observed in 20Kh13 samples with . . .
