“…These additives alter the plating procedure to produce electrodeposits with the required qualities for the applications they are intended for. It is challenging to maintain control of the plating process since these additives gradually degrade during plating and the electrodeposition process is sensitive to the additive concentration [10].…”

Electrodeposition is the method of plating metal into another by hydrolysis generally to protect against corrosion of metal. In Zinc Electroplating, Zinc is deposited on steel, where Zinc acts as a sacrificial element that enhances Steel’s life. The zinc electroplating methods are mostly affected by process parameters such as current, temperature, voltage, etc. Hydrogen is absorbed in the plated Zinc layer and later it causes cracking, which is known as hydrogen embrittlement. Hydrogen De Embrittlement is a process that removes Hydrogen. Various test methods are used to qualify a part after hydrogen de-embrittlement. One of them, the Silicon oil test was used to detect it earlier and now we have used paraffin oil for the same, thus making it cost-efficient.

Alloy-based materials such as antimony (Sb) are of interest for both Li/Na-ion batteries due to their high theoretical capacity and electronic conductivity. Of the various ways to fabricate Sb films (slurry casting, sputtering, etc.) one promising route is through electrodeposition. Electrodeposition is an industrially relevant synthetic technique that allows for the use of solution additives to control different characteristics such as film uniformity, morphology, and electrical conductivity. Solution additives such as cetyltrimethylammonium bromide (CTAB) and bis(3-sulfopropyl) disulfide (SPS) have been used to control different characteristics such as particle morphology and electrical conductivity in various electrodeposits but have not been applied to the electrodeposition of Sb for battery applications. In this study, Sb films were electrodeposited with varied concentrations of CTAB and SPS and the structure, morphology, composition, and electrochemical performance in Na-ion batteries were compared. We report that CTAB and SPS additives can significantly influence electrodeposited Sb films by altering the morphology and reduce the crystallinity, affecting the electrochemical performance. These studies provide valuable insight into the tunability of alloy-based films through electrodeposition and solution additives for battery applications.

To further study the formation and corrosion mechanisms of AM60B vanadate films, a vanadate coating was synthesized on AM60B substrate via a chemical conversion at 50°C. The morphologies of the films and the corrosion samples were observed by using scanning electron microscopy(SEM), energy dispersive X-ray analysis(EDAX) was used to analyze the elemental distribution of the film surface and the Electrochemical Impedance Spectroscopy(EIS) and the polarization curves of the films were tested by an electrochemical workstation. The morphology of conversion film is layered structure with white balls. V element preferentially deposits near the base end and the V-rich phase is easily generated on the β-phase(Mg17Al12). In the course of corrosion, corrosion begins near the α-phase(Mg). During the processes of observation and analysis, the concept of micro-zone pH gradients was discovered and applied, and attempts were made to explain some observed phenomena by using this concept. The results show that the concept of pH gradients in micro zones can be used to explain the film formation and corrosion mechanisms well.
