Optimization of Antibacterial properties of 316 Austenitic Stainless Steel

Abstract:

In the present study, titanium dioxide (TiO₂/Chitosan) nano-particles layer coatings were fabricated by electrophoretic deposition on 316 Austenitic Stainless steel substrate. Aims to enhance antibacterial properties by coating the surface with a bio ceramic (TiO₂) nano-powders. TiO₂, were made on 316 austenitic stainless steel substrate with an EPD (electrophoretic deposition) technique, charged particles suspended in ethanol at a concentration of 50 g/L, for each powder with ideal conditions of 20V and a deposition time of (2, 4 and 6 min). The surface tests of coated substrates, such as, micro-hardness, surface roughness and wettability antibacterial test were evaluated and compared to that of the uncoated substrates. The showed results the electrophoretic deposition is a favorable technique to make a bio coating on 316 Austenitic Stainless steel substrate with excellent properties and structure for applications biomedical. The results demonstrated that the coated sample under coating conditions (20V, 2min) which is close to the ratio found in living bone. the average micro-hardness of the TiO2 coated sample is 1483 HV compared with that of uncoated substrates is 460 HV. The results also of the wettability test showed that the contact angle of the deposited paint is 5.9 degrees, and this positive result is useful for biomedical applications and proved that the coating is hydrophilic.
