"The rate of silver cementation on rotating strips of aluminum canning sheet in alkaline argento-cyanide solution was measured as a function of temperature, peripheral velocityof the rotating strip, and the initial silver ion concentration. The results are compared with those obtained previously for silver cementation on copper and on zinc. The dependence of the rate constant on temperature and peripheral velocity suggests that the cementation of silver on aluminum is a diffusion-controlled process. The effect of impurities such as Au, Cu, Se and alkaline sulphides, thiosulphates and thiocyanates on the rate constant for silver cementation on aluminum was also studied. The results indicate that, in general, these impurities cause a decrease in the rate constant"--Abstract, page i. Includes abstract in French. gccst Metals Ingraham, Thomas R., author. Canada.
