整流子用无氧银铜材料的试制与性能研究

The Trial-Produce and Performance-Research of Oxygen-Free Silver-Copper Alloy Material for the Use of Commutator

介绍了“上引法”生产无氧铜杆的基本原理和整流子的用途及其对材料性能的要求 ,针对某项目和用户的具体要求 ,系统地运用了金相、抗拉强度与延伸率、电阻率、硬度、弯曲等试验手段和方法 ,对无氧银铜的性能进行了比较深入细致的研究 ,并同时进行了工业化生产的试验工作。对用“上引法”生产合金材料 ,也作了一些有益的探索。

This paper introduces the basic princies of upcasting,the uses of commutator and its demands about the performances of the material To study the performances of oxygen-free Ag-Cu alloy,we use the testing methods of metallographic,tensile strength and elongation,resistivity,hardness,bend and so on.We also Conduct some valuable research on produ cing the alloy materials using upcasting approach.
