Development of a simple 'temperature versus sliding speed' wear map for the sliding wear behaviour of dissimilar metallic interfaces II

However, raising sliding speed to 0.485 m s−1 (690 °C), 0.654 m s−1 or 0.905 m s−1 increased debris mobility and reduced residency. The now completely Nimonic 80A-sourced debris tended not to sinter and form 'glaze', and instead enhanced wear. Interestingly, oxide generation was more pronounced and wear was lower at 0.905 m s−1 than at 0.654 m s−1, despite the abrasive action and more hostile sliding conditions. The collected data were used to compose a simple temperature versus sliding speed wear map for Nimonic 80A wear when slid against Stellite 6.
