Effect of Cobalt Content on Microstructure and Properties of Ultrafine YG Cemented Carbide AITranslate
Abstract AITranslate
Ultrafine cemented carbide YG6 and YG8 with different Co content were prepared.The effect of Co content on the mechanical properties and microstructure of ultrafine YG cemented carbide was studied by surface morphology observation and physical and mechanical property test of the samples.TiCN-Al2O3-TiN multilayer composite coating was prepared on the surface of ultrafine cemented carbide by CVD me-thod.Microstructure observation, hardness measurement and cutting performance test of the coated alloy were carried out to investigate the cutting performance of the tools prepared with the alloys containing different Co content.The experimental results show that with the increase of Co content, WC grains become denser, no abnormal grain growth occurs, the hardness slightly decreases, the relative magnetic saturation strength and bending strength increase, and there are fewer fracture sources.The tool wear of cemented carbide with low Co content is more serious, the cutting performance is declined, and the tool failure is faster.
