Research On Tribological Properties Of Sulfurized Layer Of Gcr15 Steel
Keywords
Friction And Wear Of Low Temperature Ion Sulfurized Gcr15 Steel Ball
Abstract
Low-temperature ion sulfurizing technology is used to form a sulfurizing layer on the surface of GCr15 steel balls to improve its tribological properties. A four-ball friction testing machine was used to examine the tribological properties of sulfurized and non-sulfurized samples under dry friction and oil lubrication conditions. The results show that: under dry friction and oil lubrication conditions, the friction coefficient of the sulfurized sample is much lower than that of the non-sulfurized sample; under dry friction conditions, the wear rate of the sulfurized sample is significantly lower than that of the non-sulfurized sample. , this is mainly attributed to the good friction-reducing and anti-wear effect of the sulfurized layer; under oil lubrication conditions, due to the coordinated interaction of oil lubrication and solid lubrication of the sulfurized layer, the friction and wear properties of the sulfurized sample are significantly better than those without The traces on the wear surface of the sulfurized sample are shallow and light, and the wear mechanism is slight abrasive wear.
