【摘要】：先对金刚石进行化学镀镍,得到增重率分别为5%、10%、20%、30%、45%和60%的镀镍金刚石。随后以直径120μm的镀铜圆柱形琴钢丝作为基体,采用氨基磺酸镍为主盐的镀液(由80 g/L Ni(NH_2SO_3)2·4H_2O、30 g/L NiCl_2·6H_2O、3 g/L H_3BO_3和0.1 g/L十二烷基硫酸钠组成)依次进行预镀(1μm)、上砂镀(6μm)和加厚镀(6μm)。其中上砂镀是采用镀镍金刚石作为第二相进行镍-金刚石复合电镀。结果表明,选用增重率为30%的金刚石磨粒进行上砂镀时,所得金刚石线锯的表面形貌最佳,磨粒的沉积密度最高,切割性能最优。
[Abstract]:After electroless nickel plating on diamond, a nickel plated diamond with a weight gain of 5% 10% 20% and 30% 45% and 60% respectively was obtained, and then the 120 渭 m copper plated cylindrical piano wire was used as the substrate. Nickel aminosulfonic acid plating solution (consisting of 80 g / L Ni(NH_2SO_3)2 4H _ 2O _ 3 g / L NiCl_2 _ 6H _ 2O _ 3 g / L H_3BO_3 and 0.1 g / L sodium dodecyl sulfate) was used for pre-plating (1 渭 m), sand plating (6 渭 m) and thickening plating (6 渭 m), in which nickel coated diamond was used as the second phase. Ni-diamond composite electroplating. The results show that, When the diamond abrasive with weight gain of 30% is sand-plated, the diamond wire saw has the best surface morphology, the highest deposition density and the best cutting performance.
