Abstract
Mitigation against corrosion and the improvement of other properties requires surface engineering. Many ways have been adopted to achieve this purpose, including processes, methods, and materials' compositional alteration. The chromium-based coating entails surface modification processes for diverse property enhancements, such as improved mechanical and electrochemical gains with stable microstructure and chemical evolutions, as well as thermal stability, but its carcinogenic nature has demanded alternative material that is green in nature; and therefore it is legislated to be phased out. Among the green materials developed, enhanced chemical and/or thermal properties have been achieved; while some demonstrated improved mechanical properties – without a combination of chemical or thermal stability. These have limited its deployments into applications. Hence, the quest for new and advanced solutions to have green or organic materials that can potentially replace chromium-based coatings is still on course – in an attempt to beat the new extended date of phase-out, particularly from the European Union Nations by 2024. ..
