Determination of the Diffusion Coefficient in Nondestructive Testing of Thin Articles of Anisotropic Porous Materials

Аннотация

A method is proposed for determining the diffusion coefficient of solvents in thin porous materials with substantial anisotropy of their properties. The method makes possible direct nondestructive testing of articles of anisotropic porous materials. Problems of increasing the productivity and accuracy of the method are examined.
