1. Obtaining and microstructualand mechanical characterization of Ti-Nb-Sn alloys applied as biomaterial / Obtenção, caracterização microestrutural e mecanica de ligas Ti-Nb-Sn aplicadas em implantes ortopedicos
This work deals with preparation, processing and microstructural and mechanical characterization of ß type Ti-Nb-Sn alloys aiming the manufacturing of orthopedic devices for implants. Ti samples containing Nb at levels of 25, 30 and 35 wt % and Sn at levels of 2, 4 and 8 wt % were prepared by arc melting, homogenized at 1000ºC/8 h and plastically deformed

2. Stability and metastability of phases in Ti-Nb alloys / Estabilidade e metaestabilidade de fases em ligas Ti-Nb
Ligas de titânio formam a classe mais versátil de materiais metálicos utilizados para aplicações biomédicas. As ligas de Ti tipo ? usadas em dispositivos ortopédicos envolve, além de excelentes propriedades como baixa densidade, elevada resistência mecânica e excepcional resistência à corrosão, a biocompatibilidade com elementos de liga, tais co

3. Porous Structure Characterization in Titanium Coating for Surgical Implants
Powder metallurgy techniques have been used to produce controlled porous structures, such as the porous coatings applied for dental and orthopedic surgical implants, which allow bony tissue ingrowth within the implant surface improving fixation. This work presents the processing and characterization of titanium porous coatings of different porosity levels, p

4. Countermeasures to Microbiofouling in Simulated Ocean Thermal Energy Conversion Heat Exchangers with Surface and Deep Ocean Waters in Hawaii
Countermeasures to biofouling in simulated ocean thermal energy conversion heat exchangers have been studied in single-pass flow systems, using cold deep and warm surface ocean waters off the island of Hawaii. Manual brushing of the loops after free fouling periods removed most of the biofouling material. However, over a 2-year period a tenacious film formed
