WebJun 16, 2024 · The fretting wear performance of high-nitrogen stainless bearing steel (40Cr15Mo2VN) under lubrication conditions was researched. Lithium-based grease was prepared by using MoS 2 and carbon nanotubes (CNTs) as additives. AISI 52100 steel ball was used in four-ball test to evaluate the extreme pressure property and wear resistance … WebJan 1, 2024 · Bearings are among the key mechanical components for conversion from wind to electrical energy in wind turbines, but their reliability are affected by external and internal environments.

WebFretting wear involves various wear mechanisms such as adhesion, abrasion, oxidation and fatigue. At least two mechanisms occur simultaneously depending on operation parameters. Fretting wear produces oxidized wear debris and the wear coefficient increases rapidly with increasing amplitude. WebFretting is the small-amplitude oscillatory movement that can occur between contacting surfaces, which are nominally at rest. This article discusses fretting wear in mechanical components and the mechanisms of fretting wear. It describes the role of fretting conditions, such as fretting duration, slip amplitude, normal load, fretting frequency ... WebIt is caused by very slight oscillations, vibrations or slip between the metal surfaces. Fretting corrosion is a risk for bearings and it typically occurs in the loose fit between the outer … quark expeditions spitsbergen
