Title: Wear behavior of Al{sub 2}O{sub 3}, Si{sub 3}N{sub 4} and CBN cutting tool materials at high sliding speed

Abstract

Tool materials based on Al{sub 2}O{sub 3}, Si{sub 3}N{sub 4} and CBN were tested on a pin-on-disk wear machine with an AISI 4041 steel counterface under low pressure (0.25 MPa) and at high sliding speed ranging from 10 m/s to 50 m/s. The humidity of the laboratory was controlled at 50 percent during the wear tests. It was found that the wear rate of CBN was the smallest among the material at all speeds tested. The wear rate of Si{sub 3}N{sub 4} decreased from 7 X 10{sup -7} mm{sup 3}/N.m to 2 X 10{sup -7} mm{sup 3}/N.m when the speed increased from 10 m/s to 30 m/s. It then increased to 6.3 X 10{sup -7} mm{sup 3}/N.m at 50 m/s. The wear rate of the ZrO{sub 2} reinforced Al{sub 2}O{sub 3} was quite high (1.5 X 10{sup -6} mm{sup 3}/N.m) at 10 m/s, which was more than twice that of SiC whisker-reinforced Al{sub 2}O{sub 3} and other alumina ceramics tested in previous studies. The difference of the wear resistance between the two Al{sub 2}O{sub 3} based materials should be due to the additional phase of ZrO{sub 2} and SiC whiskers. The wear results have been compared with those of millingmore » tests with the same counterface at a speed included in the investigated range on the pin-on-disk tribometer. A correlation was found between the wear results and the tool life in the milling test for CBN, Si{sub 3}N{sub 4}, and SiC whisker-reinforced Al{sub 2}O{sub 3}. 8 refs., 14 figs., 1 tab.« less
