PDF | Devido ao baixo custo e facilidade de aplicação, revestimentos zinco são largamente empregados. No entanto, aplicações industriais têm exigido com melhor desempenho. O presente trabalho tem por objetivo estudar o efeito da incorporação partículas cerâmicas (talco ou bentonita) à matriz metálica zinco. Partículas talco bentonita foram utilizadas considerando caráter lubrificante das mesmas.
Subsea umbilicals are a vital component for offshore operations, being responsible to provide hydraulics, fluid injection, power and/or communication services and from subsea facilities. They can be designed both static dynamic applications deployed in harsh environments where potentially damaging factors such as corrosion, tension, pressure, clashing, entanglement, among others commonly present. For armored umbilicals, the tensile armor wires of these structures strength its fatigue life is...
In general, tensile armour wires of flexible pipes that are designed for sour applications have their strength limited to 850 MPa due the possibility embrittlement phenomena occur. A Thermally Sprayed Aluminum (TSA) coating 250 μm thick was applied high steels with UTS 1470 and YS 1280 MPa. Three specimens conditions were evaluated: full coating, no a defect. The load using four point bending fixture, maintaining constant stress 90% material’s yield strength. All tests performed in...
