Eff ect of Laser Beam Welded AISI 2205 Duplex Stainless Steel on the Viability of Fibroblast Cells

Duplex stainless steel is widely used in the oil, chemical industry and to a lesser extent in the medical industry, because of the high mechanical properties, corrosion resistance and good weldability. In recent years, because of these properties, it can enable the use in the biomedical applications. Accordingly, duplex stainless steel material can be highly important to examine the effect on the cells. In this study, the effect of the AISI 2205 duplex stainless steels which are joined by CO2 laser beam welding on the fibroblast cells has been studied in vitro for the first time. The effect of the laser beam welded samples and samples of the base metal of AISI 2205 duplex stainless steel with L929 fibroblast cells as an element of connective tissue under in vitro conditions has been studied. To study the effect of the base metal and the laser welded test specimens on the viability of the fibroblast cells were kept in DMEMF-12 medium for 7 days. The viability study was experimentally studied using the MTT method for 7 days. The cell viability of the laser welded sample has been detected to be higher than that of the base metal and the control based on 7 day data. According to the obtained results reveals that laser beam welded and base material AISI 2205 duplex stainless steel has been found suiatable to study for biomedical applications.
