Abstract

This chapter investigates the feasibility of applying a laser surface alloying technique to improve the corrosion resistance and biocompatibility of nickel-titanium (NiTi) in simulated body fluid. It summarizes the result of laser surface modification of NiTi with Mo using a CO2laser into three sections. The microstructure, chemical composition, surface morphology, hardness, corrosion resistance, nickel release rate, wettability, bone-like apatite formation and cell adhesion behavior of the surface alloyed layer were analyzed using scanning electron microscopy (SEM), energy dispersive analysis by X-rays (EDAX), X-ray diffractometry (XRD), Vicker's microhardness, polarization tests, atomic absorption spectrometry, sessile drop technique, immersion test and cell adhesion analysis.
