Abstract
Shape Memory Alloys are interesting not only for shape memory and pseudo-elastic properties, but also for relevant wear resistance near their transition temperature. NiTi has also high oxidation and corrosion resistance, and these properties together with the wear resistance suggest its use as coating to increase the lifetime of some parts. In this work we expose the results obtained with thermally sprayed coatings of NiTi using vacuum plasma spray (VPS), atmospheric plasma spray (APS) with quenching, and high velocity oxy-fuel spray (HVOF). The wear behaviour has been studied by rubber-wheel equipment and ball-on-disk tests. The results obtained at room temperature show that the APS-quenching coatings exhibit a preferential dry sliding wear mechanism, while the VPS and HVOF coatings show an abrasive mechanism.
