Study of Corrosion Resistance of Ferritic Stainless Steel 444 on Artificial Saliva
Aldinor Setiawan, Agus Suprihanto, Sulistyo
Magnetic dental veneers composed of ferritic and austenitic stainless steels are usually connected by root covers made of different dental metals in the oral cavity. Because the device is designed to serve as a seat or base for the artificial tooth to attach to the root that is already embedded in the gum, the magnetic tooth coating device is subject to mechanical interactions such as friction, which can cause wear, along with corrosive attacks from contact with saliva solution. In this study focuses on assessing the ferritic corrosion resistance of type 444 stainless steel in artificial saliva solutions with different surface roughness. Surface roughness was controlled with 80, 400 and 600 grid sandpaper and then finished with velvet cloth polishing. Tests have been carried out by determining the surface roughness value first, then the corrosion test using the Weight Loss and Linear Polarization methods. The results show that a smoother surface (0.00022 mm / y) provides a lower mean corrosion current compared to a coarser surface (0.00057 mm / y). A rougher metal surface will cause a potential difference on the surface, the rougher the greater the potential difference between the surfaces, this causes the surface to have a tendency to become corroded anode.
