Investigation of friction performance and surface integrity of cryogenically treated AISI 430 ferritic stainless steel

In this study, the effect of shallow cryogenic treatment on friction coefficient AISI 430 ferritic stainless steel was investigated. The experiments were carried out in a ball-on-disc wear tester under 5 N load at 400 rpm. As result tests, study examined surface topography traces, abrasion profile, microscopic images and hardness change traces. After applying treatment, samples increased by 7.5%. micro value around traces (Cryo) 28.4% higher than for commercial samples. width trace Cryo reduced 44%. average roughness 33.3% improved sample compared to sample.
