Influence of SiC reinforcement content and heat treatment on the corrosion behavior of pulsed electrodeposited Ni-W alloy metal matrix composite
Description
The influence of SiC content and heat treatment on the corrosion behavior of pulsed electrodeposited Ni-W/SiC composite coatings was studied by electrochemical polarization and impedance spectroscopy in 0.6 M NaCl. Structural and compositional analysis was carried out using X-ray diffraction, differential scanning calorimetry, transmission electron microscopy and depth profiling XPS analysis. It was observed that as deposited composites coatings demonstrated better corrosion resistance than heat-treated coatings. A higher corrosion and passive current density in the heat treated composite coatings was attributed to the defective nature of the passive film as indicated by Mott-Schottky analysis. A suitable corrosion mechanism is proposed and the results are rationalized based on mixed potential theory and a point defect model. This study indicate that heat treatment of coatings does not always result in better corrosion resistance.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
