Investigation of Anti-welding Performance of Nanocrystalline CuCr25 Contacts in Vacuum

摘要：

　　To investigate the anti-welding performance of Nanocrystalline CuCr25, Microcrystalline CuCr25 material was set as comparison group, electrical endurance tests were conducted in the vacuum analog device under the condition of 42V/10A DC.Then the contact surface degradation is analyzed by using FESEM.Experimental result indicates that Nano-contacts have better anti-welding performance than Micro-contacts.The Variation tendency of break arc duration is summarized, and the mechanism of that Nano-contacts have better anti-welding performance is discussed from different aspects, including surface morphology and the elements analysis of the fusion zones.
