| description | In the present invention, a method of preparing Ag-based oxide contact materials with directionally arranged reinforcing particles is disclosed, comprising steps of: a) preparing evenly dispersed composite powders by chemical co-precipitation method combining with roasting, b) granulating the composite powders by high energy ball milling, and sieving the powders, c) mixing the powders and Ag matrix in a powder mixing machine, d) cold isostatic pressing, e) sintering, f) hot-pressing, g) hot-extruding to obtain Ag-based oxide contact materials with directionally arranged reinforcing particles. This method can obtain particle reinforced Ag-based material with good electrical performance even when the reinforced (oxide) particles are very small. This method is simple, easy to operate, and does not require special equipment. The resistance to welding and arc erosion, electric conductivity and the processability of the material prepared through this present invention can be greatly improved. |
