Currently, the production of hydraulic cylinders, also used in hydraulic systemscars, tractors, airplanes, military equipment, machine tools, and other equipment,carried out by technology, the essence of which is to bring working surfacescylinders to a mirror-like state by mechanical means (turning, grinding, polishing) withsubsequent hardening of the surface layer of the cylinders. These operations are very laborious andenergy-intensive, in addition, the resource of existing hydraulic cylinders is limited (up to one millionworking cycles) due to the insufficient wear resistance of their working connecting surfaces. In thisconnection, of particular interest, is the possibility of creating a new compositea material based on silica glass capable of providing the necessary workingthe surface of hydraulic cylinders with enhanced performance properties. Keywords: hydraulic cylinder, reliability, durability, quartz material, metal, composite.
