Tribological Evaluation of PS300: A New Chrome Oxide-Based Solid Lubricant Coating Sliding Against Al2O3 from 25° to 650°C
This paper presents the tribological characteristics of Al 2 O 3 sliding against PS300, a chrome oxide-based self-lubricating coaling. Al 2 O 3 , pins were slid against PS300-coated superalloy disks in air under a 4.9 N load at velocities of 1 to 8 m/s. At a sliding velocity of I m/s, friction range...

, pins were slid against PS300-coated superalloy disks in air under a 4.9 N load at velocities of 1 to 8 m/s. At a sliding velocity of I m/s, friction ranged from 0.6 at 25° C to 0.2 at 650° C. Wear factors for the Al

/N-m range for the PS300 coating. The test results suggest that increased surface temperature resulting from either frictional heating, generated by increased sliding velocity, or ambient heating caused a reduction in friction and wear of the sliding couple. Based upon these results, the tested material combination is a promising candidate for high temperature wear applications.
