1. Wear behavior of Diamond-like Carbon Deposited on Ti6Al4V Prepared with Surface Mechanical Attrition Treatment
Surface modification by deposition of hard coatings is a way to overpass the poor wear resistance of some metallic materials and one potential material is the Diamond-Like Carbon (DLC). We investigated the wear behavior, and the adhesion of the DLC deposited on a Ti6Al4V (Ti64) alloy after Surface Mechanical Attrition Treatment (SMAT). The SMAT was applied u

2. Comportamento filtrante de geotêxtis não tecidos sob diferentes condições de apoio
O mecanismo de funcionamento de um bom filtro, seja esse formado por materiais naturais ou geossintéticos, consiste em permitir o fluxo de água simultaneamente à retenção de partículas do solo de base, garantindo a sua estabilidade. Portanto, para assegurar o bom desempenho de um filtro, existem critérios que levam em consideração fatores como reten

3. Numerical and experimental analysis of the residual stresses induced by shot peening in automotive springs. / Análise numérico-experimental das tensões residuais induzidas por jateamento com granalha em molas automotivas.
The shot peening is a cold-working mechanical process where a stream of tiny small balls is impelled against the surface of components. Each impact causes plastic deformation and introduces compressive residual stresses on the surface, which consequently increases their resistance to fatigue. This process is widely used in the automotive industry, particular

4. Influência do material do destilador na composição química das aguardentes de cana: parte II
The quantitative chemical analysis of the Brazilian sugar cane spirit distilled from glass column packaged with copper, stainless steel, aluminum sponge, or porcelain balls is described. The main chemical compounds determined by gas chromatography coupled with flame ionization (FID) and flame photometric (FPD) detectors and liquid chromatography coupled with

5. 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
