摘要
A method for determining whether surface connected, through thickness defects exist in a coated carbon-carbon composite article. The method involves the immersion of the coated article in a low viscosity liquid; if a stream of bubbles rises from the surface of the coating, such bubbles indicate the existence of at least one surface connected, through thickness defect in the coating.
