Abstract
The kinetics of dehydration and heat drying of wateratomized aluminum powders is examined It is shown that conductive vacuum ovens for reactive substances are inefficient There is no device for the disintegration of particle aggregates in dryers of this type which results in the risk of oxidation and thermal selfignition of powders Conduction–convection dryers provide disintegration of particle aggregates and continuous mixing and uniform distribution of the powder over the heating surface The results are used to optimize the drying conditions for aluminum alloy powders and determine the maximum permissible drying temperatures depending on the moisture content of the powder
