Abstract: Generally, matting components are great in dealing with a surface of friction in contacting area gripping and is focusing the service life of the mating materials. In applied components, service life can also be measured in terms of wear. Due to their higher bearing capacity and fatigue resistance, the aluminium (Al) based alloys are preferred in high-end applications. Nevertheless, due to weakened tribological strengths, many researchers explore the possible wear mechanisms existing in worn surfaces of Al based alloys to enhance the strength. Fretting is one of the primary failure mechanisms which promote severe damage to the matting of metal parts especially in Al7075 is revealed recently by the researchers. In general, damage severity during the wear is analysed through fretting which could be the result of synergy of rubbing with matting parts and vibrations. The fretting regime represents many primary wear mechanisms. Fretting map support the cause analysis of wear from the worn morphology. The present survey dealt the utilisation of fretting regime to explore the possible wear mechanisms and factors caused the wear damages from the research outcome of leading tribo research groups.
