Abstract
The article reveals a problem of improving the production technology of cutting tools made of high-speed steels by the method of generating nanostructures on their surface with the help of laser ablation. The spiked microstructures obtained on the surface of the instrument are coated with nanostructures. Experimental studies to modify the surfaces of cutting tools with laser ablation method are performed in air and in liquids. As a result of the analysis of the experimental samples surface morphology we can conclude that the modification of the surface of cutting tools made of P6M5 high-speed steel with laser pulses of nanosecond duration can be used in air and in liquids as a method of increasing the resistance characteristics of a cutting tool.
