Abstract
A study has been conducted to identify the function of titanium in 1 Cr18Ni9Ti steel and the effects of fabrication temperature, pressure, time and other variables on the strengths of diffusion-bonded alumina-1Cr18Ni9Ti. At temperatures of 750 to 1200°C, 1Cr18Ni9Ti steel was successfully bonded to alumina, with a maximum tensile strength of 19MPa. By EPMA titanium segregated to the interface of the joint, in contrast to the failure of bonding of 1Cr18Ni9 steel and alumina under the same conditions. Titanium can reduce alumina with the reactants of TiO and compounds of titanium and aluminium thermochemical calculation. Thus it is indicated that titanium is an important go-between element for bonding metal to alumina.
