    Effect of High-Chromium Ferrous-Based TiC Composite Coating on Microstructural and Corrosion Properties of Steels
    (Springer, 2023) Buytoz, Soner; Demirören, Hülya; Kaya, Esad
    Coatings are generally one of the surface protection methods used to prevent corrosion damage. However, coatings with a lean chemical content usually perform low corrosion resistance. Additive carbides could be added to enhance the corrosion resistance of the coatings. Hence, the current study focuses on the effect of TiC addition on FeCrC powder, which is frequently used as a coating material. Different proportions of TiC powder were added to FeCrC powder. 42CrMo4 steel plate was used as substrate. A gas tungsten arc (GTA) welding device was used as the energy source in the coating process. Corrosion tests were performed via a standard three-electrode system. TiC improved the corrosion resistance of FeCrC coating. The corrosion rate was observed to have an inverse proportion of TiC amount in the coating. The sample with the highest TiC powder concentration has the lowest calculated corrosion rate (25 wt %) as 2 × 10–6 (A/mm2).
