Dry-sliding and lubricated friction and wear behaviours of polyamide (PA) and ultra-high molecular weight polyethylene (UHMWPE) blend were studied using a pin-on-disc method (polymer pin sliding against a stainless steel disc) at room environment. The tribological performance of PA and UHMWPE were also investigated for the purpose of comparison. The worn surfaces were examined using a scanning electron...
Severe wear and aseptic loosening in an uncemented acetabular prosthesis have been observed in a revision surgery carried out at King Edwards VII hospital by L. Taylor and P. Heaton-Adegbile, twelve years following the primary total hip replacement operation. The superior-lateral wall of the polyethylene liner and part of the titanium cup were found to be completely worn out, such that the ceramic...
In this paper, based on an orthogonal test design and analysis method, the lubricated wear performance of a ultra-high molecular weight polyethylene and polyamide (PA-6/UHMWPE) alloys were studied using a pin-on-disc method. The effects of several parameters on the wear of the PA-6/UHMWPE alloy, rubbing against a stainless steel counterface, are reported. The main purpose was to study the influence...
This paper, based on an orthogonal experimental design and analysis method, reports the wear of a blend of polyamide-6/ultrahigh molecular weight polyethylene (PA-6/UHMWPE), using a pin-on-disc test, and rubbing against a stainless steel counterface. The wear behavior of PA-6 and UHMWPE was also investigated for the purpose of comparison. The main purpose was to study the influence of the parameters:...
