Abstract

The morphology of relief formations on the surface of a titanium alloy treated with a femtosecond laser pulse for cyclicity has been evaluated. An assumption is introduced about the presence of a segment-cyclic structure, which has a spatial repeatability formed by segment-cycles. In addition to the segment structure, a rhythmic structure with a constant or variable rhythm is also considered based on a mathematical model of a cyclic random process (stochastic case). A method has been developed for checking the cyclicity of the formed relief formations, which makes it possible to evaluate the morphology of the resulting surface and its statistical characteristics.
