Method () for the quality control of a component (), wherein the component () is heated () by an energy source (), the intensity of which is periodically modulated () at at least one frequency &#x3c9;, and wherein the amplitude A and/or the phase &#x3c6; of a heat wave () which is modulated at the same frequency &#x3c9; and is emitted by the component () is/are recorded (), wherein the particle sized of the material, from which the component () is constructed, and/or the adhesion properties F of a functional layer () applied to the component () are evaluated () from the amplitude A and/or from the phase &#x3c6;. Apparatus () for carrying out the method.
