| 中文摘要: |
| 采用电火花沉积技术,以NiCr合金为堆焊电极,在35CrMo钢表面沉积NiCr合金强化涂层。用显微硬度计测试了涂层的显微硬度,用SEM,EDX,XRD等方法表征了涂层的微观结构、化学成分分布及相组成。结果表明:涂层的表面显微硬度约为基体的2倍;涂层与基体的主要元素发生了相互扩散,涂层是由基体与NiCr合金电极发生反应形成的冶金结合层,主要成分为NiCrFe和FeNi。 |
| 英文摘要: |
| NiCr alloy coating was produced on the surface of 35CrMo steel with NiCr electrode by electro-spark deposition. The micro-hardness was obtained with hardness meter, the microstructure and chemical composition distribution and phase composition of the coating were investigated with scanning electron microscopy(SEM), energy dispersion spectrum(EDX)and X-ray diffraction(XRD)respectively. The results show that the micro-hardness of the coating is about 2 times as that of the substrate. Inter-diffusion takes place and metallurgy combination layer forms between the coating and the substrate, the main phase composition of the coating consists of NiCrFe and FeNi. |
