Advanced Surface Treatments and Adhesive Bonding Testing Schemes of Ceramic Assemblies
Abstract
Evaluation of bond strength between dissimilar materials such as those in ceramic-metallic systems has to date been qualitative, offering no quantitative comparative results. This was due primarily to the difficulties inherent in handling and machining brittle materials such as ceramics. In this study a testing scheme was developed to circumvent the mechanical property inconsistencies of a metallic-ceramic system and allow quantitative evaluation of bond strength in a titanium/alumina composite system. Using a carefully designed half-wedge configuration, results are compared to a standard full-wedge test and show comparable bond strength and strain energy release rate values. Additionally, the effects of surface treatments on the ceramic-metallic bond strength are also evaluated with the half-wedge configuration as well as the effects of surface treatment on the mechanical integrity of the alumina ceramic.
