摘要

本研究选取低碳钢1020 AISI，在应力比R= -1的室温疲劳载荷下，研究Ni纳米涂层对该金属疲劳寿命的影响。将制备好的试样在不同情况下进行40nm纳米镍电镀处理，以提高金属的疲劳极限。完成了母材和电镀处理金属的旋转弯曲疲劳试验、硬度、抗拉强度、显微组织、表面粗糙度和SEM、XRD衍射试验。实验结果表明，镀镍纳米镀层提高了钢的疲劳寿命，这主要是因为镀镍前对钢基体进行了机械和化学抛光，提高了钢的疲劳性能，而且纳米镍在钢表面分布均匀。

The Effect of Electroplated Ni Nanocoating on Fatigue Life of 1020 AISI Low Carbon Steel

Low carbon steel 1020 AISI has been selected in this study to show the influence of Ni Nano coating on fatigue life of this metal under fatigue loading at room temperature with a stress ratio R= -1. The prepared specimens are exposed to electroplated process using Nano nickel with 40 nm at diverse situations to improve the fatigue limit of metal. (SCHENCK PUNN) rotating bending fatigue test, hardness, tensile strength, microstructure, surface roughness and SEM, XRD diffraction tests have been completed for base metal and electroplating treated metal. The experimental results indicate that Ni nano coating by electroplating improve the fatigue life at due to steel substrates are typically polished mechanically and chemically before deposition to enhance the fatigue properties and nano nickel have fair distribution on steel surface.
