Book Description
Electrodeposition of Alloys: Principles and Practice, Volume I covers the general and theoretical aspects of the electrodeposition of alloy containing silver and/or copper. This book is organized into three parts encompassing 21 chapters. The first part considers first the history of electrodeposition, the applications of electrodeposited alloys, and the practical considerations involved in electrodeposition. This part also deals with the effect of operating variables on composition of electrodeposited alloys, and the physico-chemical properties of the alloy. The second part focuses on the theoretical aspects of alloy electrodeposition. This part includes discussions on the role of cathode diffusion layer, the effects of complexing agents, and the concept of alloy plating. The third part discusses the practical aspects of the electrodeposition of alloys, focusing primarily on the electrodeposition of alloys from aqueous solutions. This part examines first brass and bronze plating, followed by the electrodeposition of copper-tin, silver, and iron containing alloys. This book is directed toward electrochemists and researchers.

Book Description
Electrodeposited coatings of both zinc and cadmium are commonly used to prevent the rusting of steel parts exposed to the atmosphere. During the period of World War II the armed services and, particularly, the Navy Department were inclined to favor the use of cadmium for this purpose, as judged from their general specifications for that time. Because of the acute shortage of cadmium and cadmium plating facilities during World War II it was necessary to give serious consideration to the substitution of zinc wherever possible. This resulted in considerable controversy as to the relative merits of the two metals, particularly their protective value when applied in equal thicknesses. Previous work (1-3) had shown zinc coatings to be superior to cadmium coatings when exposed to industrial atmospheres. The tests of Blum, Strausser, and Brenner also showed zinc coatings to have somewhat longer protective life than cadmium coatings in mild, rural locations such as State College, Pa., and urban sites such as Washington, D. C. While only comparatively thin coatings were involved, it was concluded from this same work that the difference in protective value between the two kinds of coatings in marine locations was not significant. On the other hand, the results of many comparative salt spray tests had shown cadmium coatings to be markedly superior to zinc coatings under the particular conditions prevailing in a salt spray cabinet. Undoubtedly the results of these accelerated tests contributed in a large measure to the generally prevalent attitude favoring cadmium coatings in marine atmospheres. The work reported herein was undertaken to determine the relative protective value of zinc and cadmium coatings in a wide variety of environments including accelerated corrosion tests.

Book Description
Hot-dip galvanization is a method for coating steel workpieces with a protective zinc film to enhance the corrosion resistance and to improve the mechanical material properties. Hot-dip galvanized steel is the material of choice underlying many modern buildings and constructions, such as train stations, bridges and metal domes. Based on the successful German version, this edition has been adapted to include international standards, regulations and best practices. The book systematically covers all steps in hot-dip galvanization: surface pre-treatment, process and systems technology, environmental issues, and quality management. As a result, the reader finds the fundamentals as well as the most important aspects of process technology and technical equipment, alongside contributions on workpiece requirements for optimal galvanization results and methods for applying additional protective coatings to the galvanized pieces. With over 200 illustrated examples, step-by-step instructions, presentations and reference tables, this is essential reading for apprentices and professionals alike.

Book Description
Humankind's use of zinc stretches back to antiquity, and it was a component in some of the earliest known alloy systems. Even though metallic zinc was not "discovered" in Europe until 1746 (by Marggral), zinc ores were used for making brass in biblical times, and an 87% zinc alloy was found in prehistoric ruins in Transylvania. Also, zinc (the metal) was produced in quantity in India as far back as the thirteenth century, well before it was recognized as being a separate element. The uses of zinc are manifold, ranging from galvanizing to die castings to electronics. It is a preferred anode material in high-energy-density batteries (e.g., Ni/Zn, Ag/Zn, ZnJair), so that its electrochemistry, particularly in alkaline media, has been extensively explored. In the passive state, zinc is photoelectrochemically active, with the passive film displaying n-type characteristics. For the same reason that zinc is considered to be an excellent battery anode, it has found extensive use as a sacrificial anode for the protection of ships and pipelines from corrosion. Indeed, aside from zinc's well-known attributes as an alloying element, its widespread use is principally due to its electrochemical properties, which include a well-placed position in the galvanic series for protecting iron and steel in natural aqueous environments and its reversible dissolution behavior in alkaline solutions.
