Brazing of ceramic-to-ceramic and ceramic-to-metal joints in air [PDF]

open access: possibleFrontiers of Mechanical Engineering in China, 2010
Reactive air brazing (RAB) is an emerging technology for the production of ceramic-to-ceramic and ceramic-to-metal joints. In this study, RAB was investigated with respect to the potential applications for solid oxide fuel cells (SOFCs) as one example of use. It was found that alumina could be well brazed by RAB with AgCu and AgCuTi brazes.

Evaluation of the ceramic/ceramic interface

American Journal of Orthodontics and Dentofacial Orthopedics, 1994
The purpose of this study was to investigate bond strength for ceramic orthodontic brackets bonded to dental porcelain. The following factors were tested. Two types of ceramic brackets were placed on two different types of porcelain surfaces with two different bonding systems.

Wetting of ceramic-metal and ceramic-ceramic interfaces

[Proceedings] 1990 IEEE 7th International Symposium on Applications of Ferroelectrics, 2002
Contact angles of the metal-ceramic interface in a heating process were measured until the metal melted. Ag on BaTiO/sub 3/ disks melted with an almost hemispherical shape at an obtuse angle and did not wet to BaTiO/sub 3/. Metal Ag on superconducting Ba/sub 2/Y/sub 1/Cu/sub 3/O/sub 7- delta / showed better wetting than in the case of BaTiO/sub 3 ...

Hydroxyapatite Ceramic Hip Survey: Ceramic/Ceramic Bearings

Key Engineering Materials, 2007
This paper describes the clinical application of alumina ceramic and, more recently, Zirconia Toughened Alumina (ZTA), to the bearing surfaces of hip implants with a maximum follow up of fifteen years. Patients are assessed pre- and post-operatively using the Harris Hip Score.

Ceramic on Ceramic

2018
Alumina ceramic is a highly oxidized ceramic that is formed by the fusion of microscopic grains of alumina (Al2O3) and/or zirconia (ZrO2) ceramic powder into a solid phase. During the process of sintering known as “hot isostatic pressing,” the agents are pressed above 1000 bars and sintered at 1600 °C [1].

Ceramic-on-Ceramic Total Hip Arthroplasty

The Journal of Arthroplasty, 2009
Ceramic bearing surfaces have been introduced to prevent bone loss after osteolysis seen with conventional polyethylene bearing surfaces. One hundred three ceramic-on-ceramic total hip arthroplasties in 97 patients were retrospectively reviewed. Average follow-up was 50.4 months.
