抄録

The tribological properties of blends of polyamide 6 (PA 6) with the polyolefins including high density polyethylene (HDPE), low density polyethylene (LDPE), and polypropylene (PP) at various blend ratios and maleic anhydride (MAH) content were investigated and the wear morphology at the sliding interface was discussed. Tribological properties such as coefficient of friction and the specific wear rate against stainless steel disks were measured by using a pin-on-disk type tribological test apparatus. The wear surface of the polymer samples and the metal disks were observed by SEM and polarized microscope. Tribological properties obtained were related to the choice of polyolefins, blend ratio of PA 6/polyolefins and MAH content. Tribological results were explained through mechanisms such as the transfer of polymer films onto the metal disks and wear debris at the interface between polymer and metal. It was found that the unique tribological properties of PA 6/LDPE and PA 6/PP blends, lower coefficient of friction than those of the parent polymers, were mainly caused by the formation of roll debris of LDPE and PP which reduces the true contact area. Furthermore, very high wear rates of the blends with lower PA 6 contents were due to an abrasion effect of worn PA 6 particles at the interface.
