Book Description
This SAE Standard specifies the guidance and the requirements for the electrodeposition of zinc-nickel alloy coatings on a range of metallic substrates for the provision of corrosion resistance to steel components and galvanic compatibility between some bi-metallic contacting surfaces. AMS03-040A stabilizes this document because this document contains mature technology that is not expected to change and thus no further revisions are anticipated.

Book Description
Electrodeposition of Alloys: Principles and Practice, Volume II: Practical and Specific Information provides sufficient information for preparing and operating alloy plating baths. This book is organized into five sections encompassing 21 chapters that also consider the facts and theory of alloy plating. The five sections discuss the five types of alloy plating system with respect to the plating variables. Each section deals with the fundamental bases of alloy deposition, which have been summed up in six principles. This book further examines the role of diffusion in alloy deposition and the role of the density versus potential relations in alloy deposition, as well as certain misconceptions regarding their value in alloy deposition have been pointed out. This book will prove useful to electrochemists, researchers, and electrochemistry teachers and students.

Book Description
"Sacrificial metallic coatings, such as those based on Zn and Cd are used to protect steel components against corrosion. Growing environmental and health concerns have limited the use of Cd in any form since Cd plating bath is cyanide based and Cd compounds are carcinogenic. This thesis investigates Zn-Ni as a potential replacement for Cd and Cd based alloy coatings used in aerospace industries and Zn in automotive industries with respect to their tribological, corrosion and tribocorrosion resistance and hydrogen embrittlement susceptibility. In situ tribometry and additional ex situ analyses revealed that Zn-Ni coatings had superior resistance to adhesive wear compared to cadmium coatings. The microhardness of Zn-Ni coatings was higher than Zn and Cd coatings. Hardness on the wear track of Zn-Ni coatings showed the formation of strain hardened tribo layer. Zn-Ni coatings had higher polarization resistance after wear testing as compared to zinc and cadmium coatings. The mass loss due to wear enhanced corrosion was less with Zn-Ni than with Zn and Cd coatings. Zn-Ni coatings are a suitable replacement to Cd coatings when the surfaces are subjected to simultaneous wear and corrosion. Zn-Ni coatings had higher polarization resistance after the 24 hour immersion tests compared to zinc and cadmium coatings. Zn-Ni coatings offer better sacrificial corrosion protection because of low corrosion rates, and are a suitable replacement for Cd coatings. The Passivated Zn-Ni coatings showed lower corrosion resistance when heat treated due to localized damage of passive films while there was no effect of heat treatment on corrosion resistance of as plated Zn-Ni coatings. During the electrodeposition of metals, hydrogen is evolved due to electrolysis. The evolved hydrogen may diffuse outward and become trapped in the substrate/coating interface or migrate inward into the steel lattice causing delayed embrittlement when the component is subjected to stress. This study reports two principal variables for Zn, Zn-Ni, and Cd coatings: (i) quantity of hydrogen absorbed by the coating and substrate, by vacuum thermal desorption (ii) permeability of the coating material to hydrogen, by electrochemical permeation. The findings were analyzed in correlation with microstructural characteristics of both the coating material and the coating/substrate interface. With Zn-Ni, both coating process and coating material combined to significantly reduce the risk of internal hydrogen embrittlement by: (i) introducing the least amount hydrogen during the electrodeposition process, and (ii) by the ease with which hydrogen can be extracted by baking due to the presence of cracks in the coating.Keywords: Zn-Ni, Cd, Cd-Ti, Zn, EIS, insitu tribology, tribocorrosion, hydrogen permeation, TDS" --
