This paper reports on the experimental studies undertaken to detect the early stage when appears the fretting wear of the Ti-6Al-4V alloy used for the hip prostheses. Wear is a critical aspect for estimating the fretting fatigue. Studies were perform

Starting from the finding that the coatings with TiN of the total hip prostheses femoral heads made of Ti-6Al-4V alloy have tendencies to wear (abrasive, adhesive or bio-tribo-corrosion), the paper has proposed to establish the failure mechanisms of

In this work, a new scratch test method - multi-pass dual-indenter scratch test - is used to estimate the abrasion resistance of C120 steel. This steel is used in the moulds manufacture for injection of plastic materials filled with glass fibres that

This paper presents some aspects of command and control of the new generation of machines-tools with numerical control. A problem faced by numerical control programmers is related to the length (relatively long) of the programs, with implications in

Purpose The purpose of this paper is to study the roughness effect on the fixation of taper junction components and surfaces wear in terms of taper surface design. The roughness of the femoral heads’ taper and of the femoral stems’ trunnions can
