Surface modification of a-CN/TiAlN double layer coating on ASP 30 steel induced by femtosecond laser with 10(13)-10(14) W/cm(2) intensity in vacuum

Popis výsledku v původním jazyce

A double layer a-CN/TiAlN coating deposited on ASP30 steel substrate was irradiated by femtosecond laser and surface modification effects were observed. Moderate laser intensities used were in the range of 10(14)-10(13) W/cm(2), while the total thicknessof double layer coating was 4.8 mu m (a-CN = 0.6 and TiAlN = 4.2 mu m). Laser-induced changes of the surface showed dependence on laser intensity and number of accumulated pulses. Irradiations at the highest intensity resulted in preservation of one orboth layers up to 10 pulses, while at lower intensity (10(13) W/cm(2)) a-CN layer is removed after several pulses and TiAlN is preserved up to 50 pulses. Evaluated damage threshold of the target was 0.49 J/cm(2). Lower laser intensity irradiation produced periodic surface structures (LIPSS) over the entire irradiated spot with periodicity of similar to 700 nm, almost in agreement with the laser wavelength used. Irradiations carried out at the highest laser intensity (10(14) W/cm(2)) and
