查询词典 powders

In this paper, several coloring pigments were synthesized and the sheet metal powders were coated by these pigments with the technology of super powder preparing and particle compositing. The coated composite particles were prepared by these, and the metallic luster of the metal powders were defiladed. The mechanism and the processing conditions of composite particles were researched.
