Sliding Friction Pair with Different Roughness
This study demonstrates that in high-speed rotating weapon systems like Gatling guns, a smoother surface roughness (Ra3.2) significantly outperforms a rougher one (Ra6.3) by reducing peak stress and interface temperature, thereby minimizing adhesive wear and debris-induced abrasion through mechanisms described by the Greenwood–Williamson and Blok theories.
