Abstract
Dry sliding wear behaviours of polyamides of were investigated by Taguchi method using a pin-on-flat plate configuration. L9 orthogonal array and analysis of variance (ANOVA) were applied to investigate the influence of process parameters on wear rate. The experimental results indicated that Signal-to-Noise ratio (SNR) decreased with increasing elongation and decreased with increasing load slightly, but increased with increasing speed. ANOVA revealed that elongation at break exerted a great effect on the wear rate, which was followed by speed, respectively. Optimal process parameter was obtained for LFX type of polymer against smooth hardened steel.
