A series of friction and wear tests were carried out, and wear topography and friction vibration were measured. With the increase of electric current, the wear mechanism of CG30...

...Munish Kumar Gupta; Recep Demirsöz; Mehmet Erdi Korkmaz; Nimel Sworna Ross The application of stainless steel 420 is noted in various industrial sectors such as aerospace, automobile etc. However, the wear mechanism of stainless steel 420 is greatly affected by the use of 100Cr6 balls due...

... on drilling in the deep space environment. The results prove that the coefficient of friction (CoF) is interrelated with load and wear conditions, where CoFs gradually decrease with load growth in both air and vacuum. When the loads keep increasing, however, the wear mechanisms finally change under the high...

... pieces of flake debris are ground out of the severe plastic deformation caused lamellar stacked surface by high tangential stress until the COF decreases due to the generation of oxidation films and enough ball-like particles on the worn surface. In order to analyze the wear mechanism, the worn...
