Metal/ceramic joints are used in a broad range of applications in biomedicine, such as the encapsulation of implantable telemetric devices, the fabrication of crowns and bridges for dental restoration, or the production of drug delivery systems, biomedical sensors and electrodes. Apart of other characteristics, the corrosion resistance of metal/ceramic interfaces is of prime importance when biomedical applicati...
Nos últimos anos o estudo das interfaces metal/cerâmico (M/C) tem despertado grande interesse devido às diversas utilidades que estas podem oferecer em diferentes campos de aplicação prática. Um destes campos é o relativo à área das aplicações biomédicas. De entre os vários processos existentes para a produção de uniões M/C, as técnicas de união por difusão e de brasagem activa são algumas das mais utilizadas. ...
Black selective coatings of electroplated black chromium and black nickel on stainless steel, and dichromate immersion films obtained on stainless steel alloys, were studied in terms of surface morphologies and optical properties. Pretreatment conditions were optimized to obtain good adhesion and selective behaviour. The effect of heat treatment on electrolytic coatings was investigated. All three substrates pe...
