一、前言为贯彻执行毛主席关于“备战、备荒、为人民”和“独立自主,自力更生”的伟大战略方针,我厂根据生产实际需要,以理化室为主,在检查科、技术科的配合下,经过二年的努力实践,试制成一台“OL—1型复合镀层测厚仪”。该仪器与我厂以前使用的金相法、机械法等相比,具有不破坏另件镀层,速度快,准确度高,既经济又可逐件检查等优点。制成后的仪器操作简便,可测量钢,铁基体上铜、镍复合镀层每分层厚度,精度符合生产的要求,重复性、稳定度均好。
I. Foreword In order to implement Chairman Mao’s great strategic guideline of “preparing for war, preparing for famine, for the people,” and “being independent and self-reliant,” according to the actual needs of our production plant, we mainly focus on the physical and chemical laboratories. In cooperation with the inspection and technical departments After two years of hard work, trial production of a “OL-1 composite coating thickness gauge.” Compared with the metallographic method, mechanical method and other methods previously used by our factory, this instrument has the advantages of not destroying the other coating, high speed, high accuracy, economy and component inspection. After the finished instrument is easy to operate, the thickness of each layer of copper and nickel composite coating on the steel and iron substrates can be measured, and the precision meets the requirements of the production. The repeatability and the stability are all good.
