The Anti Corrosion Performance of the Fracture Surface by Fine-Blanking with Negative Clearance with ASTM-Gr.D

Abstract:

The fine blanking with negative clearance is a process with characteristic of the high blanking precision and the better fracture quality, so the blanking fracture surface structure are intensity. This paper has carried on the contrast and analysis between common blanking and the fine-blanking with negative clearance fracture face and burrs zone cavity metallographic and further indicated the different process blanking work-piece fracture face characteristics, illuminated the anti-corrosion of blanking fracture surface between different blanking process by using corrupt principium. The anti-corrosion of blanking fracture face could enhance wear resistance of blanking work piece evidently. Therefore, it could improve fatigue strength and the working life of work piece greatly.
