Abstract Scope |
The surfaces of AISI 304 steel canisters used for nuclear waste storage in hostile environments must be particularly corrosion- and wear-resistant. Recently, perhydropolysilazane (PHPS)-derived coatings have been intensively studied for their ability to provide such surfaces. In this work, various thicknesses (0.8μm, 1.1μm, and 1.4μm) of PHPS-derived coatings are successfully applied on 304 stainless steel substrates. Tribocorrosion tests were conducted using a full factorial design of experiment method with coating thickness, NaCl concentration in aqueous solution, applied load, and applied potential as parameters to estimate the material loss and current generated during tests. This study describes the methodology for developing statistically significant data to evaluate the effect of independent factors on the tribocorrosion resistance of PHPS-derived coating on 304 stainless steel surfaces. |
