奥贝氏体可锻铸铁加工中的刀具磨损

Research on Tool Wear in Anstenite-baintitic Malleable Cast Iron Cutting

在试验基础上，对ＹＧ８、ＹＧ１５、ＹＡ６及ＴｉＮ（涂层）刀具材料切削奥贝氏体可锻铸铁的磨损状况进行了比较。结果表明，刀具的磨损状态较复杂，出现了类似切削塑性金属材料时的刀具磨损状态。最后，对磨损原因进行了探讨．

On the basis of cutting austenite-baintitic malleable cast iron experiments,the wear of three kinds of carbide tools and uN coated tools is investigated. Experiments show that the tool wear is complex, and takes on some characteristics appearing in plastic metal cutting. Finally, the wear mechanism is analyzed.
