Investigating impregnation by acoustic emission method

The possibility of applying the acoustic emission method to studying the impregnation of various materials with liquid has been investigated. It is shown that in the process of liquid outgassing while impregnating hard materials, several different acoustic-emission patterns are identified. This indicates complexity and multistage character of the impregnation process. The data obtained permit to forecast the sphere of the AE method application as a nondestructive technique of depth and dip fullness control.
