| Summary: | Stainless steel AISI 316L and UHMWPE (Ultra High Molecular Weight
Polyethyene) is one of the pair of materials used for the components of the
artificial knee joint, where the Stainless Steel 316L replacement femoral
component and UHMWPE replacement tibial component, because both materials
compatibility with human tissue. Factors that affect the wear are speed, load
(pressure), surface roughness and hardness.. The aim of the study is to determine
the effect of stainless steel AISI 316L surface roughness and load on the wear
properties of UHMWPE.
The material used in this study were UHMWPE as a pin and stainless steel
AISI 316L as plat. This study used unidirectional reciprocating pin on plate
movement to measure the wear factor of UHMWPE. This wear testing was
conducted using bovine serum 25 and 75% distilled water as a lubrication. The
variation of stainless steel AISI 316L plate surface roughness were 0.02 |
