Electrochemical and Spectroscopic Study of Benzotriazole Films Formed on Copper, Copper-zinc Alloys and Zinc in Chloride Solution
The formation of protective layers on copper, zinc and copper-zinc (Cu-10Zn and Cu-40Zn) alloys at open circuit potential in aerated, near neutral 0.5 M NaCl solution containing benzotriazole (BTA) was studied using potentiodynamic measurements, electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS). The addition of benzotriazole affects the dissolution of the m...
متن کاملThe Elastic Constants of Copper Alloys
The elastic constants of single crystals of dilute solutions of Al, Si, Zn, Ga and Ge in Gu have been determined by the ultrasonic pulse method. Alloying causes a decrease in all the fundamental constants, C^, (C-^-C]^)^ and (G11 2C^2)/3> the relative decrease in (Gi2~Gi2)/2 being the greatest. The changes in shear constants Cu, and (C,-,-C-,2)/2 have been interpreted in terms of the known elec...
متن کاملChanges in Enzymatic Constitution in Zinc-deficient
The necessity of a metal ion for the activity or synthesis of specific enzymes may be revealed by growing the organism under conditions of the metal deficiency and comparing its enzyme systems with those of normal tissue. Waring and Werkman (1) reported that iron deficiency in Aerobatter indologenes resulted in the suppression of a number of enzymes. Zinc deficiency results in increased acid pr...
متن کاملZinc-Nickel Binary Alloys Electrodeposition of Steel Using Pulse Current
Zinc-Nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. In this work the effect of pulse parameters on the Zn-Ni alloy electrodeposits was investigated. The hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. The surface topography of the deposits was also observed in S...
متن کاملNear equiatomic FeCo alloys: constitution, mechanical and magnetic properties
Alloys based on the near-equiatomic FeCo offer exceptional magnetic properties. The equiatomic alloy was ‘invented’ in 1929, it offers a saturation hardly lower than that of the maximum obtained for Fe-0.35Co, with higher permeability and a lower coercivity than the latter. However, this alloy remained without industrial application, mainly because of its extreme brittleness. Only with the addi...
