利用放射性同位素研究刀具磨損的方法,就是借放射性示踪原子和射线測量仪器之助,測量放射性活化刀具切削中磨損产物(大部分粘附于切屑上,小部分粘附于試件表面和跌落入周围空間)的活度,从而折算出单位时間內的刀具磨損体积或重量,也就是磨損率。与沿用已久的測长計法相較,此法能够滿足迅速、精确、不停止切削而評定刀具磨損的要求,并能大大节省試料,因而受到各国研究者們愈来愈大的重视并提出許多研究报告。中国科学院机械研究所結合国产T_(15)K_6硬貭合金刀具进行試驗,得出了一些結果。刀片刃磨好之后,送請本院原子能研究所进行中子照射活化处理。为了滿足长距离运輸和长时間使用的要求,选用Co~(60)
The use of radioisotopes to study tool wear is measured by radioactive tracer atoms and a ray measuring instrument to measure the wear products of radioactive tool cuts (most of which adhere to the chip and a small portion adhere to the surface of the test piece and fall into Surrounding space) of activity, which is converted to the unit time the tool wear volume or weight, which is the wear rate. Compared with the long-term measuring method, this method can meet the requirement of rapid, accurate and non-stop cutting to evaluate the wear of the tool and can save the sample greatly. Therefore, researchers of this country are paid more and more attention by many researchers research report. Institute of Machinery, Chinese Academy of Sciences combined with domestic T_ (15) K_6 hard alloy tool to test, and some results. After sharpening the blade, send to our Institute of Atomic Energy for neutron irradiation activation. In order to meet the requirements of long-distance transportation and prolonged use, Co ~ (60)
