Effects of Rare Earth Elements on Wear Resistance of Ceramic Tool Materials
Through the addition of Y, Sm and Ce in Al<,2>O<,3>/ (W,Ti)C ceramic matrix, it was found that the amount and kind of the added rare earth elements have some different influences on the mechanical properties and wear resistance of the composite. Under the present experimental conditions, the flank wear curves of the selected ceramic tool materials when machining the hardened tool steel obeyed the wear law well. But wear resistance of different ceramic materials varied with each other. Wear resistance of rare earth ceramic tool materials was higher than that of the corresponding materials without rare earth. Wear modes of the developed Al<,2>O<,3>/(W,Ti)C series rare earth ceramic tool materials were mainly flank wear and accompanied with slight crater wear.
