Preparation and CMAS Wettability Investigation of CMAS Corrosion Resistant Protective Layer with Micro-Nano Double Scale Structure

Coatings, 2022
Solution precursor plasma spray (SPPS) can prepare thermal barrier coatings (TBCs) with nanostructures, which can modify the adhesion and wettability of molten silicate environmental deposits (CMAS) on the surface of TBCs, thereby improving the resistance of TBCs to CMAS corrosion. In this study, SPPS layers with micro-nano double scale structures were

Improving molten CMAS resistance of thermal barrier coatings by modified laser remelting method

Journal of Aeronautical Materials, 2022
7% yttria stabilized zirconia (7YSZ) thermal barrier coatings (TBCs) prepared by air plasma spray were laser-remelted, and subsequently pre-heated and Al2O3 sol-gel repaired for restraining the crack growth in the remelted coatings.

Effect of electro discharge machining (EDM) on the AISI316L SS white layer microstructure and corrosion resistance [PDF]

, 2013
The localised corrosion resistance of austenitic stainless steels is strongly influenced by the quality of finished surface. EDM machining induces substantial changes by the high thermal gradients generated by electric sparks.

Influence of UV light on the corrosion behavior of AA6061-T6 in a CMA solution

Journal of Materials Research and Technology, 2023
The effect of ultraviolet (UV) light illumination on the corrosion behavior of AA6061-T6 in an alkaline snowmelt-agent solution (CMA solution) was investigated using electrochemical and spectroscopic techniques. The corrosion products and passive films formed under different exposure conditions were n-type semiconductors.
