Effect of Cobalt Content on Wear Resistance of Ultrafine Cemented Carbide Tools AITranslate
Abstract AITranslate
High-speed continuous cutting test was carried out with different cobalt content of ultrafine cemented carbide tools to cut the superalloy GH2132.Based on linear regression of the test results with the least square method,the T-vcempirical formula was set up reflecting the relationship between tool life and cutting speed.And then tool wear test was carried out by high-speed intermittent cutting.Wear morphologies of tool edges and flank faces were observed with zoom stereomicroscope and photomicrography system.When the tool achieved the wear criterion,the composition of its flank wear micro-zone was analyzed by electron microprobe spectroscopy.The mechanism was discussed of cobalt content influencing tool wear resistance.The results show that both too high and too low cobalt content would result in poorer tool wear and breakage resistance.
