“…Austenitic stainless steels (SS 316L and SS 304) are commonly used in corrosive environments due to their corrosion resistance, weldability, and mechanical strength. One of the methods used to provide long-term protection against corrosion, wear, and erosion by calculating cost-effectiveness is overlay welding [5]- [8].…”

The Overlay welding process is a coating technique that is carried out using the welding process. In this study, a coating was conducted on carbon SA 516 gr. 70 with stainless steel electrodes. Welding was carried out with the GTAW and SMAW processes. The electrode used in the first coating for GTAW was ER309L while for SMAW was E309L. The next coating used in the GTAW electrode was ER316L and the SMAW electrode was E316L. In both welding processes, testing was carried out on mechanical properties and corrosion rates. Testing was carried out to determine mechanical properties, namely bending testing. This was done based on ASME IX. Bending test results in both processes are declared accepted because there are no defects. In testing the corrosion rate using the three-electrode cell method based on the ASTM G102 Overlay welding process with GTAW has a slower corrosion rate of 0.00890 MMPY compared to the overlay welding process with SMAW.

Laser directed energy deposition (LDED) can be deployed for depositing high-performance materials for various engineering applications. Alumina-forming steel is a high-performance material that possesses excellent corrosion and oxidation resistance, finding application in the power generation sector. In the present work, LDED using powder feeding (LDED-PF) was used to deposit Fe20Cr5.5AlY alloy using single-track, multi-track, and multi-layer deposition on SS 316L substrate. Response surface methodology (RSM)-based optimization was used to optimize the single-track deposition. The relationship between the track geometry parameters and the build rate with the LDED-PF processing parameters was studied. Further, the nonlinear relationship among the major process parameters was developed and an analysis of variance (ANOVA) was utilized to find significant parameters. The multi-track deposition yielded densely clad layers with a columnar grain structure. The presence of complex oxide slag of Y, Al, and Zr on the clad layer was detected. A micro-hardness of 240–285 HV was observed in the clad layer, with a hardness of 1088–1276 HV at the slag layer. The multi-layered structures showed a relative density of 99.7% with columnar growth and an average microhardness of 242 HV. The study paves the way for the deposition of dense alumina-forming steel structures for building components for power generation applications.
