Wear Friction and Corrosion Performance Assessment on IF, HSLA and DP600 Steels Subjected to Severe Vibratory Peening

Abstract

In this experimental study, wear and corrosion performance of dual-phase (DP600), high-strength low-alloy (HSLA) and interstitial-free (IF) steels after severe vibratory peening-SVP (peening durations of 30 min, 1 h, 2 h, and 4 h) were investigated. SVP is a novel surface severe plastic deformation methodology, and this study emerges the performance alteration of DP600, HSLA and IF subjected to SVP. The deformed layer thickness increased in parallel with the peening time for all samples. The highest deformation was observed in HSLA, IF and DP600, respectively. The roughness increased proportionally with the peening time but decreased for DP600 and IF under the duration of 4 h. The peening duration time provides microhardness improvement. The corrosion rates of as received (Ar) samples for DP600, HSLA and IF are 0.065, 0.13 and 0.085, respectively. SVP had a negative effect on IF (1.74) but increased the corrosion resistance of DP600 (0.034) and HSLA (0.067). The wear volume losses were 0.37, 0.274 and 0.346 for DP600, HSLA and IF at 15 N for 4 h samples, respectively. These results showed that wear and friction resistance increased under higher wear loads.
