“…The breakage of an oil film between the metal interfaces easily occurs in such sever operational conditions. Thus, the scuffing at the metal interfaces occurs owing to the metal-to-metal contact with a large contact pressure [1] [2]. Some investigators have studied the influence of surface hardness, modification treatment, contact mechanism, and lubricants on the scuffing at the metal interfaces [3] [4] [5] [6].…”

Recently, gears of high strength, reliability, and surface-damage-resistant under severe service conditions are required to achieve the weight saving and downsizing of a product. For the high-speed condition in particular, it is important to understand the influence of the surface properties on the scuffing resistance. If the effective surface profile to improve the lubrication property was found, the metal surfaces could be obtained with both surface strength and surface lubricity. Herein, the influence of surface properties modified with fine shot peening, which can form the arbitrary surface profile, on the scuffing resistance in the rolling-sliding contact machine element, was investigated. The scuffing test was performed using a two-cylinder rolling contact test machine. In a specific sliding, a faster roller of 60% and a sliding velocity of 1.75 m/s were utilized. The scuffing test results with shot-peened test rollers and those with non-shot-peened test roller were compared. The influence of the surface roughness of the shot-peened test roller was also discussed. We found that the shot-peened roller had a better scuffing resistance compared with the roller without the shot-peening process.

Tests were run on tapered roller bearings under severe operating conditions to promote the incidence of scuffing. This resulted in varying degrees of scuffing damage on the cone (inner race) ribs and/or spherical roller ends of some of the bearings. These were then examined using both the optical microscope and the scanning electron microscope (SEM). In addition, metallographic examinations were conducted on some of the damaged areas. On the basis of these observations, a qualitative model for the onset of scuffing is outlined. The quantitative data obtained from these tests was then analyzed in terms of Blok’s critical temperature criterion and also the scuffing criterion of the form WVx = constant.
