Opis:: Photoacoustic effect and photothermal radiometry were applied to characterise the thermal properties of diamond crystallites which were coated by a Cu film, a Cr film and a Cr-Cu film. The Cu-coated diamond exhibits a considerable thermal barrier at the Cu-diamond interface which had disappeared for the crystallites with a thin bond Cr layer between diamond and Cu. The comparison of the responses of both measurement techniques reveals the non-negligible influence of the optical absorption in the visible and IR on the deduced thermal parameters.

Opis:: Photothermal radiometry was applied to investigate the effect of abrasion by cavitation on steel which was supplied with a wear protecting NiTi film. Phase and amplitude data from areas on the sample which where damaged differently by the cavitation effect indicate the appearance of a three layer structure with the cavitation treatment. With cavitational impact the thermal diffusion time of the first layer decreases and an interfacial layer emerges which is identified as a surface region of the steel substrate which has undergone a stress induced transformation from an austenite to a martensite structure.

Opis:: Photothermal radiometry was applied to investigate the influence of a rolling process on the thermal properties of NiTi foils. The thermal diffusivity and thermal effusivity of the foils were determined at room temperature from the frequency variation of the photothermal signals in thermal transmission. Measurements were conducted on unrolled, rolled and thermally annealed samples. The thermal diffusivity and thermal effusivity are found to decrease considerably on rolling which is attributed to the influence of the rolling induced lattice defects.
