Özet
AISI 304L steel is widely preferred in many fields such as pipe sector, biomedical and nu-clear industry due to its wear behavior and good ma-chinability. In this experimental study, temperature-dependent wear properties and worn surface struc-tures of AISI 304L steel were investigated. All tests were conducted by using pin-on-disc test equipment under unlubricated conditions. As ambient tempera-tures, 25°C, 50°C, 100°C, 150°C, and 200°C were se-lected. The results indicated that the main friction properties, wear mechanisms, and wear rate of the worn steel samples were significantly affected by al-tering the test temperatures. It was observed that the friction coefficient oscillated at lower temperatures, but this case was quite different at higher tempera-tures. Micro observations showed that mixed defor-mation characteristic dominated by adhesive wear was observed between 25°C and 150°C while abrasive wear became more effective between 150°C and 200°C. Moreover, wear rate and specific wear rate values increased until 150°C, then dropped as a result of changing the wear mechanism and contact surface structure.
