Abstract

In this paper, we studied the method of forming of periodic surface structures resulting by the action of femtosecond laser radiation. The dependence of the formed structure pulsations period on the orientation angle of the sample was established. Studies of the formed periodic surface structures resulting by the action of femtosecond laser radiation were made on the basis of the obtained images from a scanning electron microscope. A study of the coefficient of friction of the sample before and after processing on the tribometer was carried out. It was concluded that LIPSS created on the surface of molybdenum reduced the friction coefficient by half.
