| Abstract: |
| In allusion to the problems of bad wear resistance and easy efficiency-losing, etc. of the current straw press block, the failure mechanism of the module was analyzed, a new technology on improving the properties of the module surface by plasma spraying was put forward. The effect of the voltage, electric current, spraying distance and so on on the material wear resistance was studied through test, the technological parameters of plasma spraying were optimized. The results show that the spraying current influences most significantly, and followed by the spraying distance; After the plasma spraying Ni60+50WC coating sample, wear resistance of the test sample increases greatly. |
