摘要： A method for etching fragments of aluminum or an aluminum alloy comprising the steps of: a. providing a hydrochloric acid solution in a trough-shaped container; b. inoculating the hydrochloric acid solution by chemically dissolving an amount of aluminum to produce an etching solution; c. adding the fragments to the etching solution immediately after the inoculation; d. etching the fragments for 0.5 to 10 minutes while stirring in such a way that the fragments are entrained by the motion of the etching solution; e. stopping the etching by diluting the etching solution with water; f. removing the etched fragments; g. repeatedly rinsing the fragments with water and h. rinsing the fragments with an organic desiccant. An etched fragment of aluminum or an aluminum alloy and also to a composite material comprising etched fragments.
