Variations in Wear Resistance of a Novel Triboalloy-Pseudoelastic TiNi Alloy - with Respect to its Pseudoelasticity and Hardness

It has recently been found that TiNi shape memory alloy has another attractive property: high resistance to wear. The wear resistance of this alloy benefits from its pseudoelasticity (PE). It has, however, been noticed that other mechanical properties also affect the wear resistance, especially the hardness. Research was conducted to investigate the correlation between the wear resistance and both the PE and hardness. It has been demonstrated that when the PE is high, lower hardness leads to higher wear resistance.
