Electrodeposition of Metals and Alloys

Tremendous potential exists for the growth of metal finishing industry in this century through the development of processes that are either environmentally friendly or are applicable at the nano scale. In the CEE the theoretical and experimental studies are performed to achieve such coatings. Nanostructured alloys and innovative composite materials were developed through adaptation of existing ...

Corrosion of Metals and Alloys

Although all metals are subjected to the general oxidation reaction (I), the tendencies to ionize differ from metal to metal. When two metals are exposed to an aquenous environment and release electrons according to reaction (I) , an electric potential is induced the standard value of which can be measured when the metals are in 1-molar solutions of their own salts at a predetermined temperatur...

Positron Annihilation with Electrons of Admixture Atoms in Some Binary Nickel Alloys

Weighted difference curves have been shortly presented as a proper tool allowing to analyze in another way two-detector Doppler spectra regarding positron annihilation with admixture electrons in some nickel alloys. The analysis of low and middle momentum parts of Doppler spectra for investigated alloys reflects the annihilation of positrons with admixture electrons. There is no distinct signal...

Atomic Diffusion in Metals and Alloys

Before starting this module, it is assumed that the student is familiar with the crystalline nature of metals and alloys, and understands the terms interstitial, vacancy, substitutional solid solution, binary alloy. References are made to the equilibrium vacancy concentration and it is preferable that this concept had been encountered, although backup is available both through the glossary and ...
