Abstract	The effect of compatibilizer HDPE-g-MAH of different contents on the transfer and tribological behaviors of PA46/HDPE polyblends was investigated, using a ring-on-block wear tester. All the polyblends showed friction as low as HDPE of 0.20. The wear of the polyblends was reduced when the compatibilizer ranged from 1 to 5 wt.%, showing a minimum value as 1/7 of that of PA46 when the concentration of the compatibilizer was 5 wt.%. Scanning electronic microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) analyses were used to examine the worn surface and the physical state of the acid-eroded transfer films on the counterface. It was found that the physical bonding between PA46 and HDPE phases became stronger due to the better compatibility of the polyblends. The strengthened physical bonding might decrease the peel-back process of the dispersed HDPE particles from the polyblend, enhance the adhesion between the transfer film and the counterface, and ultimately decreased the wear. The formation of a transfer film on the counterface was hardly detectable, which was the primary reason for the relatively high wear of the polyblend with excess compatibilizer.
