Sažetak
In this study, a novel attempt was made to prevent corrosion on an EN8 medium carbon steel substrate by coating it with AISI 316 stainless steel using the friction surfacing method. The ram tensile test was conducted on the sample and maximum bond strength of 504MPa, with a minimum coating thickness of 3.06 mm, was obtained. Three peak values of 42.19, 43.12 and 49.07 were obtained by the X-ray diffraction technique. A salt spray test was conducted on the samples. Two different dark yellow and dark brown rusts were observed on the substrate after 50 and 250 hours of treatment respectively. It has been found that the stability of the coating in a corrosive environment is demonstrated by its capacity to resist corrosion during the period of immersion in the electrolyte at 70°, indicating a capacitive behaviour. However, the phase angle of exposure to electrolyte for the AISI316-EN8 system became more resistive (65°) than for EN8 (45). The coating thickness has been greatly influenced by process parameters such as traverse speed, axial load and rotational speed. Coating combinations of such materials improve the service life in marine and automobile applications.
