摘要/Abstract

摘要： 将纳米复合材料技术应用于超高速陶瓷结合剂CBN砂轮试验研究，制备出力学性能和热学性能有明显改观的纳米陶瓷结合剂.与普通陶瓷CBN砂轮结合剂的实验结果相比，纳米陶瓷结合剂在耐火度、线膨胀系数、浸润性以及抗折强度上都有着显著优势，其砂轮贴片样条抗折强度达到了8823MPa，耐火度约为795℃.以此制备出的超高速纳米陶瓷结合剂CBN砂轮，不但安全性高，而且在对不锈钢、钛合金、高速钢几种难磨金属的干磨实验测试中也表现出了良好磨削性能.

Abstract: The nanocomposite technology was applied to the experimental research of super highspeed vitrified bond CBN grinding wheel， and the nanovitrified bond with markedly improved mechanical and thermal properties was developed. Compared with traditional grinding wheel vitrified bond， the nanovitrified bond， possessing the strength of wheel section samples of about 8823MPa and refractoriness of 795℃， has significant advantages in the refractoriness， thermal expansion coefficient， invasion and bending strength. This super highspeed nanovitrified bonded grinding wheel also showed excellent performance in the experiments of grinding several hardtogrind materials such as stainless steel， titanium and highspeed steel.

Key words: super highspeed, CBN grinding wheel, vitrified bond, nanomaterials, simulation of abrasion wear
