Study on microstructure and corrosion properties of Ag-Ni-Co alloy electrodeposited in low eutectic solvent
The Ag-Ni-Co alloy coating is prepared in the low eutectic solvent system by pulsed power supply technology. Infrared spectroscopy and cyclic voltammetry are used to confirm that the addition of metal salts do not change the low eutectic solvent system. When the current density is 1A/dm2 and the plating time is 40min, the plating grain is mainly spherical; the coating is uniform and dense. After testing, the surface specific resistance of the plating is only 1.295mΩ·cm2, the microhardness reaches 214.8HV, and the wear rate reaches 3.1. The corrosion resistance of the plating and the substrate is analyzed by a combination of macroscopic electrochemistry and micro-area electrochemistry, and the results show that the corrosion potential of the plating reaches -0.141V, and the corrosion current density reaches 1.299×10-7 A/cm2. The corrosion resistance of the plating is much greater than that of the substrate.
期刊介绍：
CORROSION is the premier research journal featuring peer-reviewed technical articles from the world’s top researchers and provides a permanent record of progress in the science and technology of corrosion prevention and control. The scope of the journal includes the latest developments in areas of corrosion metallurgy, mechanisms, predictors, cracking (sulfide stress, stress corrosion, hydrogen-induced), passivation, and CO2 corrosion.
70+ years and over 7,100 peer-reviewed articles with advances in corrosion science and engineering have been published in CORROSION. The journal publishes seven article types – original articles, invited critical reviews, technical notes, corrosion communications fast-tracked for rapid publication, special research topic issues, research letters of yearly annual conference student poster sessions, and scientific investigations of field corrosion processes. CORROSION, the Journal of Science and Engineering, serves as an important communication platform for academics, researchers, technical libraries, and universities.
Articles considered for CORROSION should have significant permanent value and should accomplish at least one of the following objectives:
• Contribute awareness of corrosion phenomena,
• Advance understanding of fundamental process, and/or
• Further the knowledge of techniques and practices used to reduce corrosion.
