High speed dry sliding tribological behaviors of amorphous Fe-based alloy coatings

摘要

In the present study,amorphous coatings on plain steel substrate were prepared by electric arc spraying technique.The high-speed dry sliding tribological properties of the coating were investigated on a pin-on-disc tribo-meter.The results show that amorphous phase generates in the sprayed coating.When the sliding speeds are less than 40m/s,the friction coefficient increases.The friction coefficients decrease with the sliding speed exceeding 60m/s.The wear rates increase with increasing the sliding.Phase transition occurs in the friction process.
