随着工业生产的不断发展,对工业产品质量的要求亦愈来愈高。金相检验是控制产品质量的重要手段之一。为了适应大量生产中金相检验的需要,使金相工作人员从繁重的制备试样中解放出来,我们曾经采用过化学抛光、电解抛光等试验方法,但都因其有一定的困难或某种局限性,而未能应用于大量生产中。毛主席教导我们:“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进。”于是我们总结了过去的工
With the continuous development of industrial production, the requirements on the quality of industrial products are also getting higher and higher. Metallographic testing is one of the important measures to control product quality. In order to meet the need of metallographic examination in mass production and liberate the metallographic staff from the heavy preparation sample, we have used chemical polishing, electrolytic polishing and other testing methods, but all have some difficulties or some Limitations, but can not be applied to mass production. Chairman Mao taught us: “Man always has to sum up his experience, discover something, invent something, make something, and move forward.” "So we summed up the past work
