The AFSD IN625 alloy experienced lower oxidation compared to the feed IN625 material under similar conditions due to the significantly smaller grains forming a uniform protective oxide layer during non-isothermal heating. Oxidation during isothermal heating followed a parabolic growth law in IN625 supporting Wagner’s oxidation theory. X-ray photoelectron spectroscopy and energy-dispersive X-ray spectroscopy studies revealed oxidation of almost all major alloying elements, with chromia being the predominant species. Interestingly, the formation of a continuous layer of NiO on top of chromia at 10 °C/min and 100 °C/min was observed in feed IN625, while in additive friction stir deposited discrete islands of NiO was formed. The material condition influenced the oxidation behavior while the evolution of oxides was influenced by the combined effects of heating rate and thermal kinetics.

We developed a novel strategy to control the degradation rate via interface solute segregation in surface-modified AT42-xCa alloys by friction stir processing (FSP). The effects of Ca contents on the microstructure evolution and corrosion behavior of the FSP surface-modified Mg-4Al-2Sn-<em>x</em>Ca (<em>x</em> = 0, 0.5, 1.0 and 1.5 wt%) (AT42-<em>x</em>Ca) alloys have been investigated based on hydrogen evolution tests and electrochemical measurements.

The surface modification through FSP refines the grain size and secondary phases, improving corrosion uniformity and reducing corrosion rates. The stirring zone (SZ) of FSPed AT42–1.0Ca alloy exhibits improved corrosion resistance, with a corrosion rate of ∼3.9 mm/y. The reducing corrosion rate is mainly attributed to the segregation of solute Al at interfaces of well-dispersed nano-sized CaMgSn particles and the Al-Ca co-segregation at grain boundaries of refined grains (∼2.2 μm), which accelerates the formation of Al<sup>3 +</sup> and induces the formation of a uniform and dense Al-rich corrosion product film on the corroded surface. Especially, the corrosion rate in the SZ of FSPed AT42–1.0Ca alloy decreases by ∼96 % compared to the BM counterpart.

Most of the underlying mechanisms are not easy to investigate due to the challenges in obtaining precise experimental data. In this context, physical models can be highly beneficial. This contribution presents an extension to the well-established Point Defect Model, developed to simulate, and investigate passive film dynamics. A reaction mechanism involving both chloride ion-induced film dissolution and chloride ion penetration is introduced. Additionally, a coupling approach from the passive state to transpassive metal dissolution was realized, and pH-regulating electrochemical reactions, such as oxygen reduction, were incorporated at the film/solution interface. The extended model provides transient insights into passive film forming and degrading mechanisms, and accurately captures easily measurable material responses, such as open circuit potential and the critical breakdown potential, for varying chloride ion contents. Model calibration and verification were achieved through both literature review and own electrochemical investigations with AISI 316 L stainless steel.

Furthermore, simulation results indicate the absence of chloride ions within the passive film of AISI 316 L.
