Yes. Through alloying element (chrome, molybdenum, manganese) additions and sintered density control, PM valve seats can achieve excellent wear resistance and impact toughness, and are now widely used in high-load scenarios such as high-pressure hydraulic valves and injector valve seats.
The self-lubricating effect depends on material porosity and lubricant impregnation volume. Under typical design and normal usage conditions, it can maintain stable low-friction performance over the long term; actual service life should be evaluated based on operating frequency, load, and environmental conditions.
Through precision compaction molds and controlled sintering processes, PM nozzles can consistently achieve micron-level bore tolerance uniformity, ensuring mass-production stability in fluid spray angle and flow rate.
