| Summary: | The friction and wear tests of 2205 dual-phase steel with different solution temperatures were carried out, and the effects of solution temperature on the microstructure and friction and wear properties of the steel were determined. Results show that, as the solution temperature increases, the morphology of the austenite phase in 2205 duplex stainless steel gradually changes from fibrous strips to short rods and islands with a more uniform distribution. Additionally, the ferrite content increases with a rise in solution temperature, reaching 56.3% after solution treatment at 1160°C. It was also found that, between 1000°C and 1160°C, the friction coefficient curves of 2205 dual-phase steel and silicon nitride balls have similar characteristics. Under 100 N dry friction, with the increase of solution temperature and oxygen distribution area, the wear mechanism of 2205 dual-phase steel gradually expanded from local oxidation wear to adhesive wear and exfoliation wear. |
