Features of manufacturing case of hydraulic cylinders of structural powder steel

This work examines the dependence of the structure and properties of iron-based powder materials used for body parts of hydraulic cylinders on their composition and manufacturing technology. The role and importance of powder structural materials in industrial areas, the features of the production of parts for hydraulic devices and the characteristic features of methods for strengthening parts made from these materials are also explored here. During the research, powder materials containing Fe-Cu and Fe-Cu-graphite were used to prepare the hydraulic cylinder body part. The influence of the density and porosity of sintered materials on the physical properties of steam-processed powder material, the influence of the steam oxidation regime of parts made from powder material on the microstructure, mechanical and technological properties have been studied. The development of a technological process for producing iron-based powder materials and products made from them by cold pressing, sintering and steam-thermal oxidation makes it possible to improve the structure, physical, mechanical and technological properties of these materials. The results of this study highlight the importance of optimizing the composition of powder materials and processing conditions in order to develop more reliable and durable parts for hydraulic cylinders and other hydraulic devices, and also help to identify important parameters affecting properties.
