摘要
研究了一种新型Cu-Ni-X合金的固溶时间、时效温度以及时效时间对该合金的硬度和接触电阻的影响。结果表明,该合金的最佳固溶处理工艺为1070℃×8 h,并在500℃×4 h时效条件下具有较好的综合性能,显微硬度可达到HV361,接触电阻为16 mΩ,可满足电触头在工作中的使用要求。
The hardness and contact resistance for a new kind of Cu -Ni -X alloy have been measured by measuring its solution heat treatment time and ageing heat treatment temperature and ageing heat treatment time. The results show that under solution heat treatment at 1070 ℃ ×8 h, and a good comprehensive properties can be obtained under the ageing heat treatment at 500 ℃ × 4 h. Its mierohardness can reach to 361HV , and Contact resistance to 16 mΩ, meeting the service demands.
