The 12th William Blum Lecture, Some Practical and Theoretical Considerations of Corrosion and the Role of Chromium

The corrosion of plated coatings under varying environmental conditions is discussed. The effect of polarity, porosity, combination of plate, as well as thickness and other factors on the durability of the plated product is described and touched on more fundamentally. Less well understood is the undermining effect that often occurs during plating, particularly of such metals as magnesium, aluminum, zinc and even steel. Some theoretical aspects are developed and presented.
