【摘要】 本文采用金属及氮化金属粉为粘结剂,以立方氮化硼粉为原料,在25.5×10~8 Pa、1270℃条件下用DS-0 29 B型压机合成了立方氮化硼复合体,并与高压55×10~8 Pa和高温1550℃条件下合成的立方氮化硼复合体进行了比较,结果表明,它们具有相同的结构与物相,并且本文合成的复合体内部具有更多的立方氮化硼相,从而提高了该种立方氮化硼复合体的性能。更多还原

【Abstract】 In this paper we report a new method sintering CBN compact. A mass of CBN powder with the largest dimension from 5 to 10μ was used as the starting material. The metal powder, such as Ti and Al, and their Nitrided metal powder acted as a bonding medium. A CBN compact with the excellent properties was obtained under 25.5×10~8 Pa and at 1270℃. The CBN compact is similar to normal CBN compact obtained under 55×10~8 Pa and at 1550℃ in structure and quality.更多还原
