| Abstract: | A new P/M material of valve seat which has high wearability and self-lubricating properties was developed for CNG engines,by adding rigid-grains and high-temperature solid lubricants into harden-type base material.After compared testing through a gas-fired simulation-machine,it concludes that this new P/M material has good compositive performances. |
