Investigations of Press Bonded Zinc-Rich Powder Coatings
Zinc-rich powder coatings (ZRPCs) are promising environmentally friendly alternatives to solvent-borne zinc-rich coatings. There are several difficulties and challenges with formulating and manufacturing these coatings. A novel technique without extrusion was assessed to avoid excessive wear of the …

Development of Anti-corrosive Polyester Powder Coatings
… types of additives and functional filler, namely zinc phosphate with passivation effect, zinc powder with sacrificial anode effect, and two nanoclays with barrier effect were incorporated into the coatings to enhance the anti-corrosive performance. The anti-corrosive properties were evaluated by …

Gahnite and its formation in the context of regional metamorphism and mineralization in the Namaqualand metamorphic complex
… sphalerite during metamorphism. The stability of zinc-rich spinels under a wide range of metamorphic conditions in a variety of lithologies results in its persistence in rocks where many other prograde, high temperature minerals and sulphides have been altered. Thfs has resulted in various …

Evaluating the effect of alternative neutralising agent and seeding on the zinc recovery through the Zincor iron removal circuit
Zincor's average zinc recovery was 90.29 % (for the period of 1 January 2009 to 30 September 2011), which was well below the industry standard of 96 %. Due to limitations in Zincor's iron removal technology, the maximum achievable recovery was 94 %. The zinc loss through the iron residue was the …

Behavior of advanced innovative materials for improved long-term bridge performance
… systems on existing paint including inorganic zinc / epoxy / polyurethane and calcium sulfonate coat (CAS) currently used by U.S. DOTs. The outcome of the research provides results on performance of three generic coating systems, recommendations of coating application and overcoatability, …

Investigation of New, Low-Voltage, Aluminum, Sacrificial Anode Chemistries
… corrosion behavior (per wt% added), followed by zinc and bismuth. Bismuth had only a small effect on the weight loss, galvanostatic current and potentiostatic potential. However during potentiostatic testing Al-Bi alloys showed a steady increase in current with time, indicating that larger …
