Abstract

In this research, the use of stainless steel in biomedical application was discussed in detail. Wire electrical discharge machining (WEDM) process is used to machine the stainless steel implant material by varying pulse duration and servo voltage. The machined surface is evaluated with respect to the surface quality in terms of average surface roughness, 3D surface profile, and electron imaging. Further, the machined surface is subjected to experiment on biocorrosion and cell viability. It is interesting to infer that the corrosion rate (0.00294 mm/year) was found to be minimum with an average surface roughness of 2.412 µm. The surface with minimum corrosion rate was used to investigate further with a cell viability analysis using methyl tetrazolium (MTT) assay method. The cell cultured in a standard plate were transferred to a machined surface and its behavior were noticed for twenty-four hours. Results on MTT and cell count infers, the value of cell growth is reduced by 20% on stainless steel machined surface compared to Ti-based implant material. This is due to the Fe and Ni elements present in the alloy.
