Abstract:
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.
