"Series of iron-base alloys containing manganese, phosphorus and silicon were galvanized in a hydrogen-atmosphere apparatus over a range of time and temperature conditions. Manganese in amounts of 0.17, 0.50 and 1.17% failed to exert any prominent effect on coating formation. Phosphorus-containing alloys (0. 01, 0.042, 0.069, and 1.1% P), exhibited relatively high galvanizing reactivity which was characterized by increasing unevenness in iron-zinc alloy growth with increasing phosphorus content and immersion time. The reactivity of the silicon-containing alloys (0.03, 0.08, 0.21, 0.91 and 3.4% Si) generally followed established behaviour but with some significant anomalies. Most notable was a reaction rate inversion in going from the normal galvanizing temperature of 450°C (840°F) to 470°C (880°F). At this higher temperature, the coating microstructures were significantly altered towards thinner, more compact, iron-zinc alloy layers"--Abstract, page i. Includes abstract in French.
