The Regeneration Cycle of Cobalt Chemical Conversion Waste Liquid on Aluminum Alloys

corrosion of chromate conversion coatings on aluminum alloys in electrical and electronic equipment

chromate conversion coating is applied on aluminum 6061. the optimum conditions for chromate bath composition and immersion time are also obtained for standard requirements provision such as corrosion resistance in salt spray test, electrical resistance and coating quality. the applied coatings are electrochemically tested in sea and distilled water. according to tafel and cyclic polarization c...

Effects on Structural Aluminum Alloys

HEDRICK, H. G. (General Dynamics/Fort Worth, Fort Worth, Tex.), C. E. MILLER, J. E. HALKIAS, AND J. F. HILDEBRAND. Selection of a microbiological corrosion system for studying effects on structural aluminum alloys. Appl. Microbiol. 12:197200. 1964.Two laboratory methods, a metal-strip test and a tank test, were evaluated as microbiological corrosion systems for producing corroded test specimens...

The Effects of Potassium Promoter on the Syngas Conversion of Cobalt Catalysts (TECHNICAL NOTE)

The effects of potassium promoter for production of heavy hydrocarbons from syngas with silica- supported cobalt catalysts has been studied. After preparing the catalysts in accordance with the sol-gel method, they were subjected to various tests by using a small steely micro-reactor and capable of operating in diversified situations, such as stable temperature range, flow rate, space velocity,...
