Abstract:

In the context of the increasingly urgent demand for enhancing the operational efficiency andextending the service life of mechanical–hydraulic equipment, research into solutions that minimizefriction-and wear-induced losses while improving lubricationperformance in friction pairs operating underhigh load, high pressure, and high-speed conditions has become essential. Globally, the application ofsurface micro-texturing to friction pairs has emerged as a breakthrough in the field of tribology. Micro-textures such as micro-grooves, dimples, protrusions, and other specialized geometries havedemonstrated a remarkable ability to improve lubrication effectiveness, reduce friction coefficients, andmitigate wear. These micro-texture designs have been successfully applied in several countries, includingthe United States, Austria, Turkey, Russia, and particularly China, achieving reductions in frictioncoefficient of up to 20%, extending component lifespan by 15%–35%, while also saving energy andlowering maintenance costs. This study presents an experimental investigation evaluating the practicaleffectiveness of micro-textures in improving the friction–wear performance and lubrication characteristicsof a swash plate axial piston pump. The results contributeto clarifying the role of surface micro-texturingin reducing friction and wear, controlling lubrication regimes, and enhancing the overall efficiency ofhydraulic equipment. The findings not only provide a scientific basis for applying micro-texture technologyin hydraulic devices but also reveal its potential for deployment in mechanical and energy systemsoperating under harsh conditions, particularly in Vietnam’s mining and heavy industries.
