Abstract:Cutting and wear properties of the TiC based cermets cutter with nano-TiN addition were discussed in order to provide a theoretical basis for the practical application of such cermets cutter. Wear surface and quantitative analysis of chemical composition were conducted using SEM and EDX. The results reveal that this kind of cermets cutter shows higher endurance than the conventional cermets cutter and cemented carbides cutter (YT15). Normal wear occurs under the condition of lower cutting parameters, and tipping will be the predominant failure mode when the parameters are higher. SEM analysis shows that the grain wear, oxidation wear and diffusion wear all exist. In addition, oxidation and diffusion become very obvious when the cutting parameters are large.
Key words: cutting properties; wear resistance; endurance; failure mode
