- Abstract
The microstructure of a 0.90 % nitrogen containing stainless steel pre‐deformed by cold rolling was analyzed using optical microscopy, transmission electron microscopy and X‐ray diffraction; Then the tribological behavior of nitrogen containing stainless steel was investigated using sliding wear method in air and in sodium chloride solutions and the worn surface was observed by a scanning electron microscopy. The results indicated that nitrogen containing stainless steel possessed stable single‐phase austenite and the number of mechanical twins increased with increasing cold deformation. In dry wear tests, when the GCr15 bearing steel ball and 304 stainless steel ball acted as the counterpart, the wear resistance of nitrogen containing stainless steel decreased gradually and kept nearly the same, respectively, with increasing cold deformation. The corrosion wear resistance of nitrogen containing stainless steel was improved gradually by cold deformation in the 0.9 % sodium chloride solution and 3.5 % sodium chloride solution, while their friction coefficients were nearly equal.
