| titleOfInvention | A kind of method that powder metallurgy prepares engine valve seat |
| abstract | The invention discloses a kind of method that powder metallurgy prepares engine valve seat, by having the powder metallurgy valve seat of specific components made from this preparation method, in addition to the gain effect brought by alloying element, the properties of powder metallurgy valve seat are obviously improved, the tensile strength of obtained valve seating reaches 1260MPa, radial crushing strength reaches 914MPa, and Rockwell Hardness reaches 69HRC, and toughness reaches 8.5 MPam 1/2 , the consistency of valve seating reaches 98.7%, better than powder metallurgy valve seat made from existing preparation process, meanwhile, present invention omits expensive to ooze process for copper, and manufacture cost, application easy to spread are significantly reduced on production cost. |
