Development of novel wear-resistant materials: TiNi-based pseudoelastic tribomaterials

Extensive research has being conducted at the University of Alberta to investigate the wear behavior of pseudoelastic TiNi alloy during several wear processes, including erosion, corrosive erosion, and sliding wear. The research demonstrates that this novel wear-resistant alloy is multi-functional and could be an excellent candidate for various wear applications. Attempts have also been made to develop tribo-composites using the TiNi alloy as the matrix reinforced by hard ceramic particles. This paper presents a brief review of our recent progress in developing this novel tribo-material as well as in exploring the correlation between the pseudoelasticity and the wear resistance.
