Examining the ability of palm kernel shell extract to control corrosion and assess its economic value on thermo-mechanically treated steel in artificial seawater: a sustainable and environmentally friendly approach.

Each year, the rising demand for palm oil generates large amounts of palm kernel shell waste. Discarded palm kernel shells can produce activated carbon, crushed shells, liquified fumes, and other derivatives; however, their indiscriminate disposal persists, raising issues related to the environment and economy. Therefore, the purpose of this study is to investigate the use of palm kernel shell as a corrosion inhibitor for thermo-mechanically treated steel in a seawater environment using gravimetric and electrochemical techniques, as well as surface tests at varying concentrations.

Dataset for residual stress measurements via neutron diffraction of thermally sprayed Inconel 625 coating on 304 stainless steel.

Fundamental understanding of factors and mechanisms controlling the residual stress formation in material coatings is critical for selection of optimum synthesis and deposition parameters. This article contains data from the investigation of the residual stress properties of Inconel 625 coating measured at different coating thicknesses, 250 µm,300 µm, 350 µm and 400 µm, deposited on 304 stainless steel (SS) substrate using high-velocity oxy-fuel (HVOF) spraying technique. The neutron diffraction technique was employed to measure the residual stresses of the coated specimen.
