摘要
电镀工艺参数直接影响电镀金刚石线锯镀镍层的力学性能且难以测定。按金刚石线锯电镀工艺制备电镀试件,利用纳米压/划痕仪、X射线衍射仪测试试件的力学性能,得镀镍层的硬度、弹性模量、残余应力以及镀镍层与线锯基体的结合强度。简化计算镀镍层对金刚石磨粒的把持力。根据试验获得的镀镍层力学参数建立磨粒把持力有限元模型并进行仿真分析。简化计算与仿真分析的结果一致性较好。
The mechanical properties of nickel coating on electroplated diamond wire saw are directly affected by electroplating process parameters,which are difficult to determine.Electroplating specimens were prepared according to the electroplating process of diamond wire saw.The mechanical properties of the specimens were tested by nanoindentation/scratch tester and X-ray diffractometer.The hardness,modulus of elasticity,residual stress of nickel-plated layer and the bonding strength between nickel-plated layer and wire saw matrix were obtained.The holding force of nickel plating on diamond abrasive particles was calculated.According to the mechanical parameters of nickel coating obtained from the test,the finite element model of abrasive holding force is established and simulated.The simplified calculation results are in good agreement with the simulation results.
