La_2O_3掺杂对氧化铝陶瓷耐磨性的影响

Influence of La_2O_3 Doping on Wear Resistance of Alumina Ceramic

本文研究了添加稀土La_2O_3对氧化铝陶瓷球耐磨性能的影响,结果表明:添加适量的稀土La_2O_3有利于提高氧化铝陶瓷球的体积密度和耐磨性能,当掺量为1.6wt%时,试样的磨损率降到最低,仅为0.0393‰。

Influence of La_2O_3 addition on wear resistance of alumina grinding ball was investigated. It found that both of sintering density and wear resistance were improved by adding appropriate content of La_2O_3, wear rate reached to the lowest point when the content was 1.6wt%,whose value was only 0.0393‰。
