Bond Strength of Porcelain Fused to Casting and Selective Laser Base Metal Alloy with a Bonding Agent
Purpose: The goal of this study was to assess how different bonding agents affected the shear bond strength of a feldspathic ceramic fused with a cobalt-chromium alloy that was manufactured using two different techniques: lost wax and a 3D printer. Approach: A total of 40 disks of the cobalt-chromi...

Purpose: The goal of this study was to assess how different bonding agents affected the shear bond strength of a feldspathic ceramic fused with a cobalt-chromium alloy that was manufactured using two different techniques: lost wax and a 3D printer. Approach: A total of 40 disks of the cobalt-chromium alloy were made by using casting (Co–Cr) as the control group (n=20 specimens) and additive manufacture by selective laser melting. SLM from Co–Cr (n=20 specimens) the disks were airborne particles abraded with110 µm aluminum oxide particles, then two main groups separated into subgroups based on the type of bonding agent used (with and without addition). shear bond strength was used, before the SBS test the metal and ceramic interfaces were examined using test scanning electron microscopy (SEM). The elemental makeup of the bonding agents was determined using an energy-dispersive X-ray spectroscopy (EDS) test. The results of the SBS tests as well as the failure modes were noted. Data were analyzed using the Least Significant Difference (LSD) test (a = 0.05).
Result: Bond strength was much stronger in Co-Cr specimens with bonding agents than in Co-Cr specimens without bonding agents. The mass quantities of silicon (Si) and some titanium (Ti) on the surfaces of alloys varied depending on the production method and the presence of a bonding agent.
Conclusion: By use of a bonding agent on various Co-Cr metals improves bond strength with ceramics.
