Zinc-Alloy-Plating for Corrosion Protection
Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...
متن کاملZinc Alloy Electrodeposition for Corrosion Protection
t is known that the protective value of zinc is partially a result of its ability to form a protective film when plated on a base metal, such as steel. The zinc is sacrificial and corrodes I preferentially to protectthe steel. Although pure zinc coating provides some degree of protection for the substrate, in a severe corrosion environment, zinc is consumed rapidly. For this reason, it is usual...
متن کاملZinc and Zinc Compounds
Zinc is an essential element in people’s diet. Too little zinc can cause health problems, but too much zinc is harmful. The U.S. Recommended Dietary Allowance (U.S. RDA) for zinc is 5 15 milligrams a day for humans. Not enough zinc in one’s diet can result in a loss of appetite, a decreased sense of taste and smell, slow wound healing and skin sores, or a damaged immune system. Young men who do...
متن کاملImmunobiology of zinc and zinc therapy.
In a recent article in Immunology Today, Wellinghausen et al.1 reviewed the various interactions between zinc and the immune system. The authors clearly pointed out that zinc (zinc ions and/or chelated zinc) plays an important role in the maintenance of immune function. Zinc deficiency results in hypoplasia of the immune system, impaired immune response, poor wound healing, diminished T-cell de...
متن کاملSelecting High Zinc-efficient and Assessment of Zinc Stress Tolerance of the Wheat Durum Genotypes
At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...
