Special Issue Information

Dear Colleagues,

Fretting refers to small-amplitude relative movement between contact surfaces due to mechanical vibration, fatigue load and electromagnetic vibration, etc. It leads to disastrous consequences and significant economic losses in aerospace, nuclear power, transportation and other fields. Fretting damage can be classified into fretting wear, fretting fatigue and fretting corrosion. Fretting wear refers to material removal, leading to the loss of fit in an assembly of components. Fretting fatigue occurs due to cyclic load. It facilitates premature initiation and subsequent growth of fatigue cracks, leading to a shorter fatigue life of components or failure at the stress level well below the fatigue limit. Fretting corrosion happens in electrolyte or other corrosive media. Based on the understanding of the fretting damage mechanism, corresponding measures such as structural optimization, surface modification, coating preparation and lubrication can be taken to alleviate it.

This Special Issue on “Fretting Damage and Surface Protection of Metallic Materials” will cover a variety of fretting-related topics from the perspective of the fretting damage mechanism and protection methods for metallic materials. Research papers and case studies from academia as well as industrial fields are solicited.

This paper investigates the effect of ultrasonic surface rolling (USR) on the fretting wear properties of the 7075 aluminum alloy. A white light interferometer, Vickers hardness tester, and X-ray diffractometer were employed to comparatively analyze the variations in surface roughness, hardness. and grain size before and after the USR treatment. The fretting tests were carried out under oil lubricated and dry fretting conditions, using a ball-on-flat contact tangential fretting tester. The worn surface morphology, wear debris, and chemical composition were analyzed using an optical microscope (OM), a scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS), etc. The results revealed that after USR treatment, the surface roughness was reduced by 90%, the hardness was increased by 13HV, and the grains were refined. Moreover, the wear was reduced under oil lubrication conditions but increased under dry fretting conditions. It can be concluded that the microstructure and mechanical properties of the 7075 aluminum alloy surface can be enhanced by the USR treatment. The improved fretting performance in oil should be attributed to the increased surface hardness, which helps reduce abrasive wear and plastic deformation. However, under dry fretting conditions, the wear was increased due to the presence of hard debris particles that peel off from the USR-treated surface, leading to aggravated abrasion. Full article
