Primary circuit components of water cooled power reactors have an impact on Zr-based alloys behaviour due to crud (primary circuit corrosion products) formation, transport and deposition on.

DEPOSITION OF NICKEL-COBALT AllOYS BY CONTROllED POTENTIAL ELECTROLYSIS By J. Holman 1 and L. Neumeier2 ABSTRACT The Bureau of Mines is conducting research to improve technology for the recovery of strategic and critical metals, such as cobalt, nickel,File Size: 8MB.

Additional Physical Format: Online version: Holman, J.L. (James L.). Deposition of nickel-cobalt alloys by controlled-potential electrolysis. Avondale, Md.: U.S. The research approach involves melting and casting mixed superalloy scrap into soluble anodes for electrodeposition of ni-co alloys by controlled-potential electrolysis.

The initial experimental results described in this report are from electrolytic tests using alloy anodes cast from elemental nickel, cobalt, and chromium, the main constituent Cited by: 3.

Controlled-Potential Electrolysis to Deposit Ni-Co Alloy. In theory, the controlled-potential mode of electrolysis has the advantage of selective deposition of all elements having a more noble deposition potential than the potentiostat cathode potential setting.

Subsequently, controlled potential electrolysis was carried out at potentials from − to − V vs. the saturated calomel electrode (SCE) on VC and from − to − V vs. SCE on Ti cathode. An electrorefining process to recover nickel, cobalt, chromium and other metals from mixed and contaminated superalloy scrap was developed by the U.S.

Bureau of Mines. The process is based on controlled potential electrolysis (CPE) to selectively deposit a nickel-cobalt alloy and permits the recovery of chromium, tungsten and molybdenum as.

By varying the deposition potential outer layers with compositions ranging from pure titanium over NiTi to nickel-rich alloys such as could be obtained. nickel-cobalt, nickel-niobium, nickel. Water electrolysis is a promising approach to hydrogen production from renewable energy sources.

Alkaline water electrolyzers allow using non-noble and low-cost materials. An analysis of common assumptions and experimental conditions (low concentrations, low temperature, low current densities, and short-term experiments) found in the literature is by: 6.

Abstract. This chapter is devoted to nonmetallic electrode materials, i.e., electrode materials which are neither metallic, nor semiconducting. A large portion of this chapter deals with materials which have proved their worth in actual processes, e.g., carbon and graphite, and another part describes new materials that may prove of much value to the scientist and technologist in the near : J.

Randin. A robust water-splitting catalyst is fundamental for the effective conversion of solar energy into chemical fuel (H 2) via electrochemical and photoelectrochemical water splitting. In water splitting (2H 2 O → 2H 2 + O 2, ΔE° = V), the oxygen evolution reaction (OER or water oxidation, 2H 2 O → O 2 + 4H + + 4e –) is known to be more complicated than the hydrogen evolution reaction Cited by: 3.

A great deal of progress has been made in the development of materials, their application to structures, and their adaptation to a variety of systems and integrated across a wide range of industrial applications.
