2015)Brazing of hexagonal boron-nitride ceramics with VT1-0 titanium alloy using a rapidly quenched titanium-based brazing alloy, Welding International, 29:3, 222-226, A brazing alloy was developed for the brazing of boron-nitride ceramics with VT1-0 alloy in the form of nanostructured rapidly quenched tapes. The wetting capacity of the boron-nitride ceramics by the brazing alloys of the Ti-Zr system is evaluated. The surface of the brazing alloy tape was investigated by X-ray diffraction and topographic methods and the brazed joints between theVT1-0 titanium alloy and boron-nitride ceramics were studied by examination of microstructure and mechanical properties.

For the first time, a design of a modular ceramic ball head of a total hip joint replacement (THR) friction pair has been developed, which has the properties of a metal in conjunction with the stem neck and the properties of a ceramics on bearing surface of the pair. This is achieved by creating a low-cost, low-toxic, durable fixed connection of the head made of alumina or zirconia ceramics and the titanium-based alloy sleeve to obtain a brazed joint that is efficient in human synovial fluid. With the help of finite element analysis, a quantitative assessment of the strength and rigidity of the proposed head design was performed and its use in modern hip arthroplasty was indicated. The approbation of the proposed design solutions for creating a THR ceramic head with a titanium-based alloy sleeve brazed was carried out.
