Hardness of Electrodeposited Plating Film of W-Ni Alloy

Nanoindentation and micro-mechanical fracture toughness of electrodeposited nanocrystalline Ni–W alloy films

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...

The Mechanical and Electrochemical Properties of DC-Electrodeposited Ni-Mn Alloy Coating with Low Internal Stress

The nickel-manganese (Ni-Mn) alloy coating prepared from DC electrodeposition process in sulphamate bath was studied. The effects of process parameters, such as current density and electrolyte composition, on the cathodic current efficiency, microstructure, internal stress and mechanical properties were investigated. Because of its crucial effect on the application to the electroforming of micr...

DEVELOPMENT OF A TUNGSTEN HEAVY ALLOY, W-Ni-Mn, USED AS KINETIC ENERGY PENETRATOR

Abstract: The objective of this research was to develop a tungsten heavy alloy (WHA) having a microstructure and properties good enough to penetrate hard rolled steels as deep as possible. In addition this alloy should not have environmental problems as depleted uranium (DU) materials. For this purpose a wide spread literature survey was performed and on the base of information obtained in ...
