| titleOfInvention | One kind mixing manganese orthorhombic phase stannic oxide reinforced Ag-based electrical contact material and preparation method thereof |
| abstract | The present invention relates to one kind to mix manganese orthorhombic phase stannic oxide reinforced Ag-based electrical contact material and preparation method thereof, belongs to electrical contact material technical field.The following Ag-based electrical contact material of main technical schemes, the material including following mass percent: silver: 80wt%-98wt%；Second phase: 2wt%-20wt%；Second phase is the tin oxide containing manganese.The fibre length of second phase is 0.1 micron~1000 microns, and diameter is 0.0010.01 microns~100 microns, and draw ratio is (2:1)~(200:1)；The molar ratio of tin and manganese element is (4:1)~(100:1) in second phase；Tin oxide reinforced phase is fiber morphology in the silver-tin contact material of this method preparation, and having part is orthorhombic phase tin, and during arcing, orthorhombic phase can be undergone phase transition, secondary enhancing contact material, to improve the working life of contact. |
