Abstract
The effect of the surface treatment on the fretting wear behavior of 316LVM austenitic stainless steel was investigated in the Ringer's solution by a Servo Hydraulic Dynamic Test machine. Three kinds of surface treatments were used in the experiments, namely low-temperature plasma nitriding at 430°C, carbonitriding at 430°C, and carburising at 500°C, respectively. The experimental results indicated that all the three treatments created a layer of ″S″ phase on the sample surface, which effectively improved the hardness and elastic modulus of 316LVM and further enhanced its anti-corrosion and anti-wear properties. The 316LVM nitrided at 430°C showed the similar friction behavior as that carbonitrided at 430°C. Even the 316LVM carburised at 500°C exhibited the lowest friction coefficient; the low-temperature plasma carbonitrided at 430°C was the best surface treatment of three against the fretting wear of medical grade 316LVM austenitic stainless steels in this experiment.
