摘要

Ag-SnO/sub - 2/触点是用挤压法制造的，因为这种方法更容易达到高密度。然而，这种材料的脆性，特别是含有12%或更多的氧化物，导致制造成本高。本文讨论了一种专利材料，它使用烧结助剂和特殊的银形态来帮助烧结到高密度。通过这种方法，可以通过粉末金属混合，压制，烧结和压制到高密度来制造离散触点。获得了与挤压材料相似的电气性能。报告了电气测试结果，包括在90a 240 VAC下的寿命测试和焊接强度比较。讨论了侵蚀过程。

Press-sinter-repress Ag-SnO/sub 2/ contacts with lithium and copper sintering additives for contactor applications

Ag-SnO/sub 2/ contacts have been made by extrusion for several years because it is easier to achieve high density by this method. However, the brittle nature of this material, especially with 12% or more oxides, resulted in high manufacturing cost. This paper discusses a patented material that uses sintering aids and special silver morphology to assist sintering to high densities. By this method, discrete contacts can be made by powder metal mixing, pressing, sintering and repressing to high densities. Electrical performance similar to extruded materials was obtained. Electrical test results including life testing at 90 A 240 VAC and weld strength comparisons are reported. The erosion process is discussed.
