Tin dioxide in terms of physical properties on steel AISI 316 LVM

This paper aimed to investigate the physical properties of SnO2 coatings deposited by atomic layer deposition on 316LVM stainless steel for biomedical applications. New assessment strategies for tin oxide functional materials are of fundamental importance in the development of new surface of biomaterials. Thin films of SnO2 have good substrate adhesion and could be deposited even on clean glass substrate. Tin oxide (SnO2) has a similar crystal structure like TiO2. It is believed that SnO2 can have a similar effect on TiO2 by inducing the formation of a calcium phosphate layer. Additionally, tin dioxide with nanocrystalline impurities has been reported to exist antibacterial activity. As part of the work, the SnO2 layer was deposited by using the atomic layer deposition (ALD) method. The application process was carried out for a different number of cycles. In the first stage study of abrasion resistance and coating adhesion to the substrate were carried out. The surface topography was examinated using atomic force microscope (AFM) and wettability test were also complemented. Obtained results may form the basis for the development of more detailed criteria for the assessment of the final quality of medical devices used in the skeletal system, which will ensure the required biocompatibility of implants and contribute to minimizing the risk of postoperative complications.
