| 摘 要： | 以超高速陶瓷CBN砂轮的结合剂低温高强性能要求为目标,在以化学纯原料为主的R2O+RO-B2O3-Al2O3-SiO2玻璃体系基础上,引入纳米改性剂来对陶瓷结合剂基体进行改良强化。4种成分结合剂性能的测试结果表明,纳米陶瓷结合剂的抗折强度、耐火度、浸润性与普通陶瓷结合剂相比有着显著优势。4号纳米陶瓷结合剂的抗折强度达到了83.75MPa,耐火度降至795℃,其膨胀系数也与CBN磨料更为接近,是一种更适合用于制备超高速陶瓷CBN砂轮的结合剂。

| Abstract: | In order to achieve the requirements of super-high speed vitrified bond of
CBN grinding wheel with low-melting and high strength, nano-materials were added into formulations of the vitrified bond which was mainly based on a glass with properties of R2O+RO-B2O3-Al2O3-SiO2,a compound of pure raw chemical materials.Performances of four types bond were tested.Experimental results show that compared with traditional vitrified bond the new nano-ceramic bond has a significant advantages at its bending strength,refractoriness and infiltration.Especially,the bending strength of 4# nano-ceramic bond has reached 83.75(MPa) and its refractoriness was 795℃,and its expansion coefficient is the closet to CBN abrasive.It proves that 4# nano-ceramic bond is more suitable for super-high speed CBN grinding wheel. |
