Development and preparation of Fe-based powder metallurgy valve plate used in hydraulic motor |
| |
Abstract: | As thekey component of hydraulic motor, valve plate shows the characteristics of complex multi-step shape structure and high mechanical property requirements. Replacing the original casting process, the high quality and qualified Fe-based valve plate used in hydraulic motor was produced by powder metallurgy technology. The raw Fe-based materials wereselected carefully, the forming mold was designed reasonably, the sintering melting process was controlledintensively, and the heat treatment parameters were optimized. In the results, the Fe-based powder metallurgy valve plate can satisfy the application requirement of hydraulic motor. |
