“…On the other hand, the surfaces of the HSS pins were partially oxidised ( Fig. 8a and b) during rubbing the wear particles, and the patchy black area is considered to be wear-protective tribofilms [38,39]. This process was facilitated by the higher temperature (Fig.…”

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.

A high-temperature self-lubricating composite NiAl-Cr-Mo-CaF 2 was fabricated using the powder metallurgy technique, and the tribological behavior of the composite at a wide range of temperatures (room temperature to 1000°C) was investigated. The results showed that the composite had a favorable friction coefficient of about 0.2 and an excellent wear resistance of about 1 9 10 -5 mm 3 N -1 m -1 at the high temperatures tested (800 and 1000°C). The excellent self-lubricating performance was attributed to the formation of the glaze film on the worn surface consisting mainly of CaCrO 4 and CaMoO 4 as high-temperature solid lubricants.
