Two-step thermal oxidation was proposed for Ti and Ti alloys as a surface-treatment process for preparing an anatase-containing TiO2 layer. This process consisted of treatment in a CO-containing atmosphere (first step) and subsequent treatment in air (second step). In this chapter, first, the current status of TiO2 coating onto Ti and Ti alloys for biomedical applications is reviewed; then our ...

An ultrasound-assisted activation method for electroless silver plating is presented in this study. When the ultrasound was applied during the activation step, the amount of the Pd species adsorbed on substrate surfaces was higher than that of sample pretreated with a conventional activation process without ultrasound irradiation. With this activation method, it was also shown that the adsorbed...

Radar absorbing materials, i.e. magnetite (Fe3O4) coated carbon fibers (MCCFs) were fabricated by electro-deposition technique. Black-colored single spinel phase Fe3O4 nanoparticles was easily synthesized by hydrothermal method using reduction of a Fe (III) - Triethanolamine complex in an aqueous alkaline solution at 60-80 ◦C. Uniform and compact Fe3O4 films were fabricated on nitric acid treat...

In this work, two advanced technologies were applied for manufacturing a bimorph wavefront corrector: laser ablation, to vaporize conductive silver coating from piezoceramic surface, and parallel-gap resistance microwelding, provide reliable electrical contact between the piezodisk surface electrodes copper wires. A step-by-step guide mirror production is presented, together with ‘bottlenecks’....
