Linear sweep voltammetry has been used as an “in situ” technique to characterize thin layers of ZnNi alloys. The zinc dissolution peak potentials from ZnNi deposits were found to be more noble [El,= -0.7V (SCE) and Ez,= -0.575 V (SCE)] than those of the pure metal ions [-OX3 V (SCE)] due to a formation of two ZnNi intermediate phases 7 and 6 respectively. The effect of d c and pulse parameters ...

Zinc coatings are commonly used to protect steel from different types of corrosion. However, zinc is an electrochemical reactive metal; applying surface treatment galvanized materials usually necessary increase the system's lifetime. An alternative method for improving service life these use corrosion inhibitors. Nicotinic acid, chemically formulated as C 5 H 4 NCO, a water-soluble vitamin. It ...

The melting temperature of nanoparticles can be 10K-100K lower than the bulk materials due to higher value of surface by volume ratio. According to Gibb's-Thomson relation:-  4 1 sl m m b f s d d T T H             But there has also supper heating phenomenon in case of embedded nanoparticle. Now we are going to discus melting of Zn-nanoparticles. Zinc is widely used in galvanizing...

in this paper, hardness and tensile properties of welded zone of aluminum 1100 alloys by friction stir welding process was investigated and the effects of rotational and traverse speeds of tool on these parameters was studied. also the fracture cross-section of welded samples was investigated. according the results of this paper, the hardness of weld material is higher than base material and is...

A partially fluorine substituted hydroxyapatite- (FHA-) coated Mg-Zn alloy was prepared to investigate the interfacial behavior of degradable Mg-based biomaterials with degradable bioactive coatings in a cell culture environment. Peaks from the results of X-ray diffraction (XRD) were characterized and compared before and after cell culture. It was found that Ca-P, including poorly crystalline i...

In the manufacturing industry, surface structures and topographies present at functional areas of mechanical parts play a vital role in various performance characteristics, such as corrosion resistance, weldability, wear behaviors, etc. Copper–zinc alloys are extensively used industry. Laser ablation has potential to create variety on ablated substrate. The size geometry largely depend selectio...
