The news correspondents obtained a quote from the research, "However, on a microscopic scale, surface roughness undulations are employed to accentuate the frictional contact for an enhanced mechanical locking effect. Macroscopic (global) modelling for fretting wear-fatigue prediction of two head/stem material combinations, namely, Co-28Cr-6Mo against direct metal laser sintering Ti-6Al-4V (Ti64) and forged Ti-6Al-4V, is investigated. The significance of fretting wear and fatigue in a hip joint for 10 years of service in a normal-weight male for moderately intense exercise is predicted for both material combinations. A micro-scale fretting wear-fatigue model of the surface undulation submodel is developed to predict wear and fatigue micro-cracking. A key aspect is the development of a multiscale wear-fatigue algorithm using adaptive meshing."
According to the news reporters, the research concluded: "Both material combination joints are shown to have sufficient wear resistance with direct metal laser sintering Ti64 performing better in terms of both fretting wear and fatigue."
