Estimating the wear behavior of hdpe composites reinforced with nano alumina fillers using taguchi method

with a specific wear rate equal to 2.6652 10 -6 in mm 3 /N.m, as well as the most effective parameters on wear rate are arranged as nano content, applied load, and the sliding time. In contrast, SEM observation was considered to understand the wear mechanism. The addition of nano Alumina fillers prevented the test specimen surface from lessening by creating a transfer film separating the contact zone results from the self-lubricant behavior generated in prepared composites. In contrast, deep grooves, adhesive marks, and debris particles were generated in pure HDPE specimens, resulting in low hardness and weak wear resistance.
