| titleOfInvention | Method for preparing Ag/La1-xSrxCoO3 electric contact composite material |
| abstract | The invention relates to preparation of an electric contact composite material, and aims to provide a method for preparing an Ag/La1-xSrxCoO3 electric contact material. The method includes preparing conductive ceramic micro-nano-powder of an La1-xSrxCoO3 system by a sol-gel method; uniformly mixing the La1-xSrxCoO3 micro-nano-powder and silver powder in a V-shaped powder mixer, and leading the La1-xSrxCoO3 powder to account for 8-20% of the total mass of mixed powder; and isostatically pressing the uniformly mixed powder into a blank, sequentially realizing sintering, re-pressing and re-sintering processes and finally obtaining the Ag/La1-xSrxCoO3 electric contact composite material by means of thermal extrusion forming. The Ag/La1-xSrxCoO3 electric contact composite material is prepared by the sol-gel method, a wild phase La1-xSrxCoO3 in the composite material is nano-level powder, the melt viscosity in micro-molten pools on the surface of the electric contact material under effects of electric arcs can be improved by the high specific surface area of the wild phase, performances including the electric conductivity, the mechanical strength, the abrasion resistance, the electric arc ablation and the like of the electric contact material are comprehensively enhanced, and the problem of difficulty in processing and forming is avoided. |
