The crystallinity degree influence on the weather resistance of CF/PPS composites
Polyphenylene sulphide (PPS) is a semi-crystalline high-performance thermoplastic used in the aeronautic field as a composite usually reinforced with carbon fibers. The crystallinity of semi-crystalline thermoplastics can ...
Rough turning of titanium alloy (6Al-4V)
Metal machining is the complex process due the used cutting parameters. In metal cutting process, materials of workpiece differ widely in their ability to deform plastically, to fracture and to sustain tensile stresses. ...
Stacking faults in SiCf/SiC composite obtained by chemical vapor reaction process
SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...
Evaluation of double treated starches using thermal tools.
(In: CONGRESSO BRASILEIRO DE ANÁLISE TÉRMICA E CALORIMETRIA, 10.; CONGRESSO PAN AMERICANO DE ANÁLISE TÉRMICA E CALORIMETRIA, 4., 2016, São Paulo. Trabalhos. [S.l.]: ABRATEC, 2016., 2016)
Influence of thermal treatments in the corrosion behaviour of HVOF Cr 3C2-NiCr coatings
Thermal spray coatings as Cr3C2-NiCr obtained by high velocity oxy-fuel spraying (HVOF) are mainly applied due to their behaviour against aggressive erosive-abrasive and corrosive atmospheres and their thermal stability ...
Microstructural effects on fatigue crack growth behavior of a microalloyed steel
Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
Friction and wear of performance of MoDTC and ester-containing lubrificants over steel surfaces under reciprocating conditions
(Centro Congressi InternazionaleTorino, 2013)
Since the earliest developments of human history, friction has been a major issue. From the invention of the wheel and the use of the first lubricants to the studiesof coated and microtexturized surfaces, significant effort ...
Viscosity of fluoroindate glasses
The viscosity of two fluoroindate glasses was measured as a function of temperature in the range of 310 °C - 362 °C. In such interval, the viscosity values were found to be similar to those reported for fluorozirconate ...
Mortar added by tyre rubber residues: Characterisation in fresh and hardened state
Due to the progressive increase of vehicles, the number of used tires is globally one of the serious environmental problems faced now. Therefore, several researches have being developed for its reuse. The use of tires' ...
