| 摘要 |
The subject of the invention is a method for determining the quality of an adhesive connection between a metallic material and a polymer, which can be used especially to assess the quality of electric and electric-power equipment containing metal parts embedded in epoxy resin. The method consists in conducting a two-stage examination, where in stage one standard samples are examined, and in stage two the adhesive connection is examined by delivering an acoustic emission signal to this connection, measuring the output signal of the acoustic emission after its propagation in the structure of the metallic element, the adhesive connection and the non-metallic material, and comparing the measured signals with the acoustic emission signals that have been obtained in stage one for adhesive connections of known properties. |
