| Abstract: |
| In this paper the electronic scanning technique and energy spectrum analysis have been employed to analyze the surface of the copper plated welding wire produced under different technological conditions with a viwe to studing the morphology of wire and the cause of defect occurring. The ressults show that the propcrties of the solid lubricant used during drawing exerts a direct influence on the wire surface quality. On this basis、a more satisfactory twistincss bele lubricant with bilaver is devcloped.This lubricant can improve many of the properties of lubricating film,This paper has also made a the orctical calculation of the thickness of lubricating film as well as an analysis and discussion on the physical factors affecting the thickness.The authors suggest a method to test and analyze the thickness of lubricating film. |
