The Use Of Dbd Plasmas For Treatment Of Pdms Surfaces And Adhesion Improvement
(IEEENew York, 2016)
Some reflections on the future of the water quality of the corumbataí River basin, São Paulo state, Brazil
The waters of Corumbataí River in the middle and eastern part of São Paulo State, Brazil, are extensively used for human consumption; their water quality has been modified mainly due to increasing pressure caused by ...
Effect of green machining on distortion and surface finishing in advanced ceramic
An alternative for grinding of sintered ceramic is the machining on the green state of the ceramic, which presents easy cutting without the introduction of harmful defects to its mechanical resistance. However, after ...
Production and heat treatment of cast graphitic steels with additions of niobium
The optimal combination of the mechanical characteristics of austempered spheroidal graphitic cast steel together with modern casting techniques yielded an economically promising product. The maximum potential of the usage ...
Surface modification of Ti-30Ta alloy by electrospun PCL deposition
In this study, PCL electrospun fibers were deposited on the Ti-30Ta alloy for change the surface properties. Experimental Ti-30Ta alloy was obtained by melting titanium and tantalum in arc melting furnace with argon ...
Atmospheric plasma treatment of carbon fibers for enhancement of their adhesion properties
Plasma processing of carbon fibers is aimed to provide better contact and adhesion between individual plies without decrease of the carbon fiber (CF) mechanical resistance. This work deals with surface modification of CFs ...

300 M steel was developed from high-strength steel SAE 4340, the goal of this improvement was get better toughness and weldability in applications requiring improved mechanical properties; with small changes in alloy ...
Development of silicon carbide substrates for aerospace applications
Payload and high-tech are important characteristics when the goals are aerospace applications. The development of the technologies associated to these applications has interests that transcend national boundaries and are ...
Treatment of polycarbonate by dielectric barrier discharge (DBD) at atmospheric pressure
(Iop Publishing Ltd, 2014-01-01)
Generally most plastic materials are intrinsically hydrophobic, low surface energy materials, and thus do not adhere well to other substances. Surface treatment of polymers by discharge plasmas is of great and increasing ...
