“…The current investigation used single-point, ex situ scratch tests to produce controlled abrasion damage on previously oxidized metal alloys and used surface analysis tools to characterize the effects of further high-temperature exposure on the damaged areas. It extends prior work on the Ni-based alloy that has been reported elsewhere [8]. …”

“…On the other hand, the Cr 2 O 3 oxide debris was pressed and sintered on the surface of the HSS pin and formed a glaze layer (Fig. 11a and b), which is beneficial for reducing friction and wear [40,9,[41][42][43] and the wear track of the disc showed a metallic colour and some black wear particles, definitely Cr 2 O 3 , were located in the worn track and on the surface of the disc. The disc material was transferred to the pin surface because there was no protection against metal-to-metal contact because of the breakdown of the oxide scale on the disc surface.…”

L. (2016). Influence of Cr-Rich oxide scale on sliding wear mechanism of ferritic stainless steel at high temperature. Tribology Letters, 63 (2), 1-13.Influence of Cr-Rich oxide scale on sliding wear mechanism of ferritic stainless steel at high temperature AbstractThe tribological tests of a ferritic stainless steel (FSS) 445 in contact with high-speed steel (HSS) were performed on a high-temperature pin-on-disc tribometer. Wear exhibited significant difference when the FSS 445 was oxidised with a Cr-rich oxide scale on the surface. The HSS pin displayed adhesive wear when there was no oxide scale on the stainless steel disc, and in the early stages, the coefficient of friction fluctuated significantly, but the level of wear changed as Cr2O3 particles formed. The wear was then reduced, and the coefficient of friction remained stable. The Cr-rich oxide scale which formed on the stainless steel was able to stabilise the coefficient of friction, to reduce the wear rate and to help form a glazed layer on the HSS surface. The abrasive wear of the HSS pin took place at 850 °C, indicating that the hardness of the Cr-rich oxide scale increased as the temperature decreased.

“…At low temperatures, the oxide films are extremely beneficial since they form rapidly and effectively suppress adhesive wear. For example, in a nickel-chromium alloy, at temperatures of about 700°C, the higher mobility of chromium promotes the formation of chromium oxide rather than nickel oxide on the surface [66]. The oxide layers formed are supported by the strain-hardened substrate layers which are generated due to plastic deformation.…”
