Abstract
In this study, 316L stainless steel materials, which are widely used in the industry, were produced by investment casting management. Depending on the microstructure, the hardness values constitute an important stage of the properties that can be developed and controlled. For this purpose, the differences between the microstructure and hardness properties of 316L stainless steel, which is produced by the investment casting method, and 316L stainless steel, which is currently used commercially, were examined. The changes caused by the fiber laser on the surface of 316L materials produced with two different production methods were examined. It was observed that the laser used made different changes in the surface structure of the 316L material produced by both methods. Since the surface of the material is a buffer between body fluids and biomaterial, it is known that there is a relationship between surface properties and biocompatibility. In this study, the L929 cell growth test, one of the cytotoxicity tests, was applied and thus, how laser surface treatment affects the biocompatibility of 316L materials produced by both methods was comparatively examined.
