前言测定金属材料沿深度方向应力分布需逐层剥离技术,为尽可能地保持原有的应力状态,常选用电加工方法。但由于试样几何形状和精度等因素,限制了常规的电抛光或其它电加工方法的应用。本文设计并制做了特殊的电解装置,采用阳极保护方法,既满足了测试面精度和平整度要求,又保证了试样在一定加工深度下的平行性,取得了较好的结果。实验结果和讨论 1.实验用电解装置的设计制做因试样的测试面较狭窄,当电解到一定
Preface Determination of the distribution of stress along the depth direction of the metal material to be stripped layer by layer technology, in order to maintain the original state of stress as possible, often using electrical processing methods. However, the application of conventional electropolishing or other electrical processing methods is limited due to factors such as sample geometry and accuracy. This paper designed and made a special electrolytic device, the use of anode protection methods, not only to meet the requirements of the test surface accuracy and flatness, but also ensure that the sample at a certain depth of parallelism, and achieved good results. Experimental results and discussion 1 experimental design of the electrolytic device to do because of the test specimen surface is more narrow, when the electrolysis to a certain
