Abstract: | In this study the wear volume map is obtained and considered for evaluation of the abrasive wear performance for polyamide
(PA6) and PA6 composites. Polyamide composites were tailored using 25 wt.% glass bead, 20 wt.% talc and 30 wt.% wollastonite
fillers. In this work, the influence of filler materials, abrasion surface roughness and applied loading values on abrasive
wear performance of PA6 and PA6 composites were evaluated. Experimental abrasive wear tests were carried out at atmospheric
condition using pin-on-disc rig arrangement. Tests were performed under 4, 6, 8 and 10 N load values, traveling speed of 1 m/s
and abrasion surface roughness values of 5, 20 and 45 μm. Wear volume maps were obtained and the results showed that the lowest
wear volume rate for PA is reached using glass bead filler. Furthermore, the results also showed that the higher is the applied
load and the roughness of the abrasion surface, the higher is the wear rate. Finally it is also concluded that abrasive wear
process mechanism include ploughing mechanism and delimitation of filler tips. |
