| 摘 要： | 随着科学技术的发展和薄膜材料的广泛应用,对于薄膜材料的性能的研究已经越来越引起人们的重视,尤其是其力学性能.因此,着重对电沉积镍涂层中的力学性能如硬度和杨氏模量等进行了研究.首先介绍了用纳米压痕的方法测量薄膜的硬度与杨氏模量的原理和方法,然后对电沉积后未经处理、经真空热处理和激光处理的样品进行了载荷-深度曲线的测试.结果表明,经过真空热处理的样品硬度明显减小,而经激光处理后的样品的硬度比未经处理的样品要高. 同时,对于同一样品,加不同的载荷导致压痕深度不同,随着压痕深度的增加其测得的硬度值和杨氏模量值都会有明显的下降. |

| Abstract: | With the development of the science and the widely uses of the films or coatings, the research of the properties of the films attachs much interest of the researchers, especially mechanical properties. In the paper, the hardness and Young's modulus of nickel coating are investigated. The principles of nano-indenter to measure the hardness and Young' s modulus of nickel coating are introduced. The relation curves of the load and displacement are obtained, including the original electrodeposited samples and the samples undergoing annealing and laser thermal shock. The results revealed that the hardness of the samples undergoing annealing is less small while that of undergoing laser thermal shock is slightly lager compared with the original electrodeposited samples. Moreover, the indentation depths change with the load, the hardness decrease with the increasing of the depth. |
