Popis: Increasing production rates of parts, toughening of operation modes and load increasing, reduce the service life of equipment. The destruction of the tool usually begins with the surface, so its strengthening is one of the main factors of improving the resource and reliability. Hardening the working surfaces with laser radiation is the most effective and promising method of hardening tools that are used under friction conditions. This article presents the results of experimental study of the laser hardening process of a band saw made of 9CrV tool steel; a mathematical model based on these experiments was made to show the connection of the parameters of pulse laser radiation and the depth of the resulting hardened area. It shows that the pulse energy and the movement speed for pulse laser hardening with the chosen parameters have a decisive influence on the depth of the hardened area.
