Evaluation of Zirconia Nanofiller and Brass Alloy Assembly by X-Ray Radiography

Abstract

Zirconia samples were linked with brass alloy using different nanofiller types. These nanofillers were formed with different concentrations of copper, silver, and titanium nanopowder metals. They were prepared by mixing powders, compacting them by pressure, and sintering them by tube furnace with argon atmosphere at 1,200°C for 50 min. Zirconia/brass assemblies were joined in a vacuum furnace with the pressure of 2 × 10 −5 torr at 900°C for 15 min. X-ray radiography was used to evaluate and detect the defect in the contact area. Some defects were detected. The shear test was achieved to determine the joint strength. Finally, a relationship was found between X-ray radiography and the shear test.
