晶粒长大抑制剂对超细硬质合金刀具磨损性能的影响
Influence of grain growth inhibitor on wear resistance of ultrafine cemented carbide cutting tools
摘要
Abstract
The wear resistance tests of cutting tools of superalloy GH2132 have been performed for WC-10Co ultrafine cemented carbide cutting tools with and without added grain growth inhibitor.Linear regression of the testing resulting has been conducted, and TL-v empirical formula relating the service life of cutting tool with the cutting speed has been established.The wearing mor-phology of cutting edge and rear face of the cutting tool has been observed under ZEISS microscope with a magnification of contin-uous times and photomicroscope.And the energy spectrum analysis of electron probe has been done in the wearing micro-region of rear face of the worn-out cutting tool.The influencing mechanism of grain growth inhibitor on the wearability of cutting tool was in-vestigated.It has been concluded that the grain growth inhibitor can enhance the wearability of ultrafine cemented carbide cutting tool,that is,not only has the ability to resist adhesive wear been improved,but also has the ability to resist abrasive wear,tear stripping and diffusive wear.关键词
