| titleOfInvention | Preparation method of whisker particle hybrid reinforced silver tin oxide electric contact alloy |
| abstract | The invention discloses a preparation method of whisker particle hybrid reinforced silver tin oxide electric contact alloy, which is implemented according to the following steps: step 1, preparing tin oxide whiskers; step 2, preparing tin oxide particles; step 3, preparing whisker particle hybrid reinforced silver-tin oxide composite powder by using tin oxide whiskers and particles; step 4, preparing whisker particle hybrid reinforced silver-based electric contact alloy by using the silver-tin oxide composite powder; the preparation method of the whisker particle hybrid reinforced silver tin oxide electric contact alloy can control the form of tin oxide in a silver matrix, improve the dispersibility of second-phase tin oxide in the silver matrix and ensure that second-phase oxides in the alloy are uniformly distributed; and because of the skeleton constraint action of the tin oxide whisker in the silver tin oxide electric contact material, the uniformity of a second phase can be maintained under the action of arc erosion, so that the performance and the service life of the silver tin oxide electric contact alloy are improved. |
