摘要
采用磁控溅射技术,在Ni-Cr合金表面溅射一层Ti薄膜作为中间层,研究了Ni-Cr/Ti/瓷界面组织结构,产物种类、分布及反应机制。结果表明:Ni-Cr/Ti/瓷界面反应复杂,界面处形成的新物相有Ti2Ni,AlTi3,TiO2,SnCr0.14OX,NiCr2O4和Cr2O3。高温烤瓷过程中,Ti与Ni以稳定的化合物Ti2Ni形式结合,同时Ti与陶瓷中Al2O3反应生成AlTi3化合物,与SnO2和SiO2发生置换反应生成TiO2,TiO2与陶瓷中氧化物结合,更好的实现了Ni-Cr合金与陶瓷的连接。
Ti film was sputtered on Ni-Cr alloy substrate with magnetron sputtering and so it acted as an interlayer for Ni-Cr/porcelain interface.Microstructure,products category,distribution and reaction mechanism of bonding interface of Ni-Cr/Ti/porcelain have been investigated.Experimental results showed that the Ni-Cr/Ti/porcelain interface was very complicated and the interface has new phase composition with Ti2Ni,AlTi3,TiO2,SnCr0.14OX,NiCr2O4 and Cr2O3.During the high temperature firing,AlTi3 compound was produced by the reaction between Ti and Al2O3 in porcelain,stable Ti2Ni compound between Ti and Ni,and TiO2 produced by the displacement reaction between Ti and SnO2,SiO2,etc,then TiO2 reacts with the oxides in porcelain and exits with sosoloid mode.Ti interlayer reacts with porcelain as well as Ni-Cr alloy during high temperature firing after sputtering Ti interlayer on Ni-Cr alloy surface which can realize the bond Ni-Cr alloy with porcelain.
