Wear behavior of carbon steel electrodeposited by nanocrystalline Ni–W coating
Ni-W coatings, compared to pure nanocrystalline Ni, exhibit higher hardness and wear resistance. In some cases, these coatings are considered as environmental friendly alternatives for hard chromium coating. Till now, most of Ni-W coatings have been produced by direct current electrodeposition from alkaline baths. In this study square pulse current was used for deposition of Ni-W precipitates f...

متن کاملEvolution of Morphology and Microstructure in Electrodeposited Nanocrystalline Al–Mg Alloy Dendrites
Nanocrystalline Al–Mg dendrites were fabricated through galvanostatic electrodeposition. Initially feather-like morphology was formed exhibiting morphological evolution to smooth globules at its tips. With eventual deposition, rough globules formed over the smooth ones. The feather-like and smooth globules possessed supersaturated face centered cubic (fcc)–Al(Mg) phase with ~7 and ~20 at.% Mg r...
متن کاملAbrasive wear response of nanocrystalline Ni–W alloys across the Hall–Petchbreakdown
The abrasive wear of nanocrystalline Ni–W alloys with grain sizes of 5–105 nm has been studied using Taber abrasion testing. The wear resistance of the finest grain size specimen is found to be higher than would be predicted based on hardness alone. This deviation from Archard scaling is traced to mechanically-driven structural evolution, consisting of grain growth and grain boundary relaxation...
متن کاملThe effect of TiO2 concentration on microstructure, corrosion behavior and wear behavior of Ni-P-W-TiO2 coating
Nickel-phosphorus coatings (Ni-P) are widely used in industry due to their high hardness, corrosion resistance and very good mechanical and chemical properties. Oxide particles such as TiO2 can be used to increase the wear resistance of these coatings. In this study, the Ni-P-W-TiO2 composite coating was deposited on the AISI 304L steel substrate using the electroplating method. Electroplating ...
