Alkali and zinc chlorides in waterwall tube corrosion: Effects of pure salts and mixtures

A prognostic physicochemical model for choosing complexes for chromium-plating solutions is constructed on the basis of a combination of the thermodynamic principles and data on the kinetics of some electrochemical reactions. It is shown that high-quality chromium coating can be produced from solutions of Cr(III) complexes, whose logarithm of stability constants ranges from 10 to 20, and the logarithm of stability constants of Cr(II) complexes formed in electrolysis ranges from 7 to 10. The influence of the nature of ligands on chromium electrodeposition is studied. Using the model proposed, a chromium-plating solution based on a chromium(III) malonate complex is developed. This solution makes it possible to produce high-quality coatings in a wide interval of current densities.

Lecture Notes in General and Inorganic Chemistry Part 2, 2017

In second part of Lecture notes in General and Inorganic Chemistry provides an introduction to the chemistry of inorganic molecules. The emphasis is on basic principles of electrochemistry, redox equilibria, electrolysis and corrosion, properties of important metals and nonmetals. Written primarily for use as a textbook for a university-level course, the topics covered here provide the fundamental tools necessary for an accomplished engineer.
