基体梯度结构对TiN涂层硬质合金抗氧化性能的影响 祝昌军1,陈康华1,王社权1,2,徐银超1,谢灿强1,陈响明2 (1. 中南大学 粉末冶金国家重点实验室,湖南 长沙,410083; 2. 株洲钻石切削刀具股份有限公司,湖南 株洲,412000) 摘要:采用阴极弧蒸发涂层工艺在均质和梯度硬质合金基体上沉积TiN涂层;运用金相观察,XRD检测和SEM分析,研究基体梯度结构对TiN涂层硬质合金抗氧化性能的影响,对涂层硬质合金氧化开裂过程进行分析.研究结果表明:基体结构梯度化后,TiN涂层的表面形貌由平整状变为网状结构;梯度基体表面韧性区的存在提高了TiN涂层硬质合金的抗氧化性能;在 into the steel, the ratio of equiaxed crystals increased by 20%. Therefore, how to obtain dispersed TiN particles with a small particle size and a high number density is of great significance to refine the high... J. Cent. South Univ.
