摘要
电火花加工中,电极材料是影响加工质量和加工效率的重要因素。将SiC微粒作为第二相电沉积成分来制备Cu基SiC复合电极材料,研究了微粒添加量、微粒粒径、电流密度及镀液温度等工艺因素对复合铸层中SiC颗粒共沉积量的影响,以及SiC颗粒对铸层表面形貌的影响,并进行了电极材料的抗电蚀性试验。结果表明添加SiC颗粒的复合材料的表面相对平整、致密,晶体更细小且均匀。相对电极损耗明显降低,抗电蚀性能得到提高。
In electrical discharge machining, electrode is an important factor which influences machining quality and efficiency. The SiC particles were added into the solution to make copper-based composite by using electro- forming technology. The influence of diameter of SiC particles, current density, electroforming temperature on the SiC content was studied. Influence of SiC particles on surface micro morphology was also studied. Electrical discharge machining experiments were carried out to study its corrosion resistance. Results show that the grain of SiC reinforced copper-based composite is small and the surface is compact. Relative electrode removal rate decreases and its corrosion resistance is improved.
