    Interface Performance of Electrodeposited Nickel Coating in Stamping Process

    • 摘要: 采用有限元方法对电沉积镍涂层钢带的冲压成形过程进行了数值模拟,得到了电沉积镍涂层在界面上的应力场、应变场等冲压成形特性.计算结果表明:在冲压过程中,涂层与基体界面上的应力大小、拉压性质都是变化的,且正应力一般在-50~50MPa之间,剪应力一般在-40~30MPa之间;界面上涂层中的应变比基体中的应变大得多,但两者在变形过程中是比较匹配的.

       

      Abstract: Finite element method was used to simulate the stamping process for electrodeposited nickel coating by using a plane model.The stress and strain fields at the interface were obtained within the nickel coating and steel substrate.The computational results shows that the value and property for the stress at the interface were variational.Generally,the normal stress was between -50~50MPa,and the shear stress is between -40~30MPa.The strain in the nickel coating might be much greater than in the substrate.But they were approximately matchable during the stamping process.
