摘要

Wear failure is a common failure mode for the industrial components manufactured by stainless steel (SS), primarily influenced by service load and temperature. Consequently, elucidating the tribological behavior and mechanism is crucial under various load and temperature conditions. Under dry friction conditions, the coefficient of friction (COF) of 304L SS sliding against a Si₃N₄ ball increased from 0.51 to 0.76 with the increase of the load from 5 to 15 N. The influence of temperature (25–400 °C) on the COF was more pronounced than that of load (from 0.71 to 1.21), which primarily attributed to intensified adhesive behavior. The analysis of the wear behavior under different load and temperature conditions revealed that the wear rate of 304L SS progressively increased with the increase of the load from 5 to 15 N (from 1.53 × 10⁻⁸ to 2.81 × 10⁻⁸ mm3/(N mm)). The wear mechanism included adhesive wear, abrasive wear, and oxidative wear, with adhesive wear being the dominant mechanism. The wear rate increased more significantly as temperature rose (from 2.49 × 10⁻⁸ to 9.56 × 10⁻⁸ mm3/(N mm)), and the wear mechanism still included adhesive wear, abrasive wear, and oxidative wear. However, the dominant mechanism was transformed from adhesive wear to the mixed adhesive-oxidative mechanism.
