Investigation into the wear behaviour of Tribaloy 400C during rotation as an unlubricated bearing at 600 °C

▶ Wear properties of Tribaloy 400C was investigated in a bespoke bearing rig at 600 °C. ▶ Stable wear protective oxide films often referred to as 'glazes' were formed. ▶ Six stages were identified in the formation of the 'glazes'. ▶ During the formation of the 'glazes' discrete oxide films were formed within them. ▶ Eventually the 'glazes' were composed of a uniform distribution of oxides.
