变形对镍镀层纳米压痕尺寸效应的影响及预测
Influence of Deformation on Nanoindentation Size Effect in Nickel Coating
摘 要
为了研究拉伸变形对电沉积镍镀层硬度尺寸效应的影响,用纳米压痕仪对变形前后的镍镀层进行了测试,并通过两种模型对其进行了预测.结果表明:对于镀态和经过10%拉伸变形的镍镀层,压痕硬度随着压痕深度的降低而增加;试验结果能够很好地通过GCV模型来拟合,而Nix-Gao模型只有在压痕深度>100 nm时才能和试验结果相吻合;纳米压痕硬度尺寸效应对于经过拉伸变形10%的试样更加明显.

Abstract
To investigate the influence of tensile deformation on the nanoindentation size effect in electrodeposited nickel coating,experiments were conduct by nanoindenter and the results were predicted by two models.Both in as-deposited state and with a tensile strain of 10% nickel coating,the indentation hardness increased as the indentation dimension decreased.The experimental results can be accurately described by GCV model.However the Nix-Gao model can fit the experimental results only when the indentation depths is more than 100 nm.The indentation size effect is more pronounced in coating with tensile strain of 10% than in as-deposited state.
