摘要：

Electrodeposition of metals and stirring experiments that provide suspensions of cermets necessary for electrocodeposition have been carried out in the low-gravity environment produced on a KC-135 aircraft. Variation of the rate of electrodeposition was not found to affect the crystalline form of the deposits with our experimental configuration. Stirring experiments carried out to determine the feasibility of suspending and dispersing diamond and chromium carbide particles in aqueous zinc sulfate demonstrated that suspension occurred, but coagulation or clumping was evident in the suspension. Aggregation in the suspension was found to increase as the concentration of the ZnS04solution was increased. Addition of a negative wetting agent decreased clumping. Comparisons of these results to previous low-gravity electrodeposition results are discussed. Ramifications of these results on the design of apparatus for longer low-gravity experiments are presented. © 1989 by Clyde Riley. © The American Institute of Aeronautics and Astronautics, Inc.
