Internal stress of high tungsten content Ni-W alloy coatings
ABSTRACTThis study investigates the impact of current density on the microstructure, composition, and internal stress of Ni-W alloys electrodeposited in a citrate system. Using XRD, SEM, EDS, TEM, and XPS, it was found that tungsten serves as a solute in a Ni-W FCC structure oriented in the (111) direction. Increasing current density led to higher tungsten content and current efficiency. The addition of 2-Butyne-1,4-diol altered the carbon content, significantly reducing internal stress by promoting carbide formation near grain boundaries, which prevented coating shrinkage during hydrogen escape. This carbon enrichment improved the alloy's corrosion resistance.KEYWORDS: ElectrodepositionNi-W alloyinternal stresscarbon contenthigh tungsten contentnanocrystallineAmorphous materialsElectrochemical corrosion Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by National Natural Science Foundation of China: [Grant Number 52174280]; Science and Technology Support Program of Jiangsu Province: [Grant Number SYG202022].
期刊介绍:
Surface Engineering provides a forum for the publication of refereed material on both the theory and practice of this important enabling technology, embracing science, technology and engineering. Coverage includes design, surface modification technologies and process control, and the characterisation and properties of the final system or component, including quality control and non-destructive examination.
