Abstract
Nickel-Titanium (Ni-Ti) is an intermetallic alloy that has exhibited a unique ability to recover its original shape after deformation, and this ability is well known as the so-called shape memory effect. On the other hand, with the special behavior of pseudoelastic/superelasticity, Ni-Ti shape memory alloys (SMAs) also draw widespread attention in a wide range of engineering fields. Ni-Ti SMAs used to be considered as some kind of smart materials due to the shape memory effect and pseudoelastic/superelasticity performance. However, Ni-Ti SMAs have attracted increasing interest in tribological applications over the past two decades owing to their excellent wear resistance, which is mainly ascribed to their pseudoelasticity. On account of this point, Ni-Ti alloys have also been chosen as surface strengthening materials to improve the wear performance of various substrates using different surface technologies. From the view of process selection and performance estimation, this review suggests the research progress of preparation and application of Ni-Ti alloys as strengthening material.
