    Description / Table of Contents: Corrosion tests with nickel-plated sheets of killed and rimmed steelWith a number of different types of steel plates (killed and rimmed steel, Thomas steel, Siemens Martin steel, square steel), research has been carried out on the influence of the base metal on the effectiveness of the corrosion protection afforded by the galvanic nickel plating. With plates of the different types of steel subjected to the same finishing treatment, neither the short-time ferroxyle test nor the salt spray test nor storage under moist conditions revealed any noticeable differences in the corrosion resistance of the nickel plating. Minor differences between different types of plates, as they are sometimes observed with out door corrosion, were not noticeable with the short-time test.The investigations lead to the conclusion that, contrary to widespread opinion, killed steel can be nickel-plated with the same corrosion protection effect as rimmed steel.
    Notes: An verschiedenen Stahlblechsorten (beruhigter und unberuhigter Stahl, Th-, SM- und VK-Stahl) wurde der Einfluß des Grundmetalls auf den Rostschutzwert der galvanischen Vernicklung untersucht. Bei gleich vorgeschliffenen Blechen der verschiedenen Stahlsorten ergab die Kurzprüfung im Ferroxyltest, im Salzsprühversuch und bei der Feuchtlagerung keinen deutlichen Unterschied der Rostbeständigkeit der Vernicklung. Feinere Unterschiede, die bei der außenatmosphärischen Korrosion bei verschiedenen Blechsorten teilweise beobachtet wurden, ließen sich im Kurzversuch nicht feststellen.Auf Grund der durchgeführten Untersuchungen ist zu schließen, daß im Gegensatz zu einer verbreiteten Meinung beruhigter Stahl mit gleicher Rostbeständigkeit vernickelt werden kann wie unberuhigter.

    Notes: A survey of compounds that undergo polymerization in the solid state supports the topochemical postulate that such a reaction is possible only if the monomer crystal structure affords close contact between the reactive centers of neighboring molecules. Even when this condition is fulfilled, chain propagation may be diffusion-limited because of the contraction of the chain on polymerization. When the crystal structure makes such contraction unnecessary, polymerization can proceed without diffusion and the crystal can exert a direct control over the geometric course of the reaction. Several kinds of structures are known in which such behavior has been demonstrated or can be expected.
