Effect of nanometer Ti(C,N)on property of vitrified bond for CBN abrasives

Na₂O-Al₂O₃-SiO₂-B₂O₃ based vitrified bond was selected as the main research subject.Vitrified bond for nanometer titanium carbonitride could be obtained by adding 2%,4%,6% and 8%mass fraction nano-Ti(C,N)into the basic glass material.The flexural strength values were gained by CMT4504 electronic multifunctional tester. Furthermore, differential thermal analysis and microstructure of vitrified bond for nanometer Ti(C,N)were examined by LCP-1poor thermal expansion and Stemi 2000-C electron microscope,respectively.The results showed that after being added to 2%,4%,6% and 8% mass fraction nano-Ti(C,N),the mobility of the vitrified bond was about 179.80%-193.33% and the values of bending strength were among 33.55-116.38 MPa.The comprehensive performance of vitrified bond with 6% mass fraction nano-Ti(C,N)was optimal.Compared with basic glass material,its bending strength and mobility increased by 39.92 MPa and 22.9%,respectively,with performance greatly improved.
