Effect of interfacial variables on metal-porcelain bonding.
While ceramic-to-metal bonding has been used in many applications, the actual chemical and physical factors leading to optimum bond strength are not well understood. In this work, several variables affecting the bonding between dental porcelain and a palladium alloy (85% Pd, 10% Cu, and 5% Ga) were investigated: 1) precoating the metal by sputtering various oxides before porcelaining; 2) peroxi...
متن کاملThe relationship between oxide adherence and porcelain-metal bonding.
The lack of a reliable bond test has hindered the elucidation of the mechanism for porcelain-metal bonding in dental systems, because a test capable of detecting differences among porcelain-metal bonds of various qualities is required before the reasons for these differences may be ascertained. A method was developed in the present study whereby specimens of alloys with differing physical prope...

Adhesive bonding is enlarging its application range as a practical method for the joining of dissimilar materials in automotives, aircrafts, microelectronics and medical devices industries replacing conventional joining techniques such as welding, bolting and riveting [1-5]. Especially for joining of fiber-reinforced polymer (FRP) composites to other structural materials such as metal, traditio...
متن کاملBonding of Metal Orthodontic Attachments to Sandblasted Porcelain and Zirconia Surfaces
This study evaluates tensile bond strength (TBS) of metal orthodontic attachments to sandblasted feldspathic porcelain and zirconia with various bonding protocols. Thirty-six (36) feldspathic and 36 zirconia disc samples were prepared, glazed, embedded in acrylic blocks and sandblasted, and divided into three groups according to one or more of the following treatments: hydrofluoric acid 4% (HF)...
