A aplicação de ferramentas Gestão Projetos em pesquisas acadêmicas ainda não é amplamente difundida, seja por resistência ou falta aprofundamento relação aos conceitos relacionados a essa área conhecimento. Uma pesquisa acadêmica, como um doutorado, caracteriza-se projeto único, com duração limitada e, frequentemente, possuindo significativa complexidade, podendo se beneficiar significativamente da gestão projetos para atingir requisitos qualidade, atendimento ao escopo e prazos requeridos....

Modelling eco-efficiency is becoming a wide field of research shown by large body scientific literature on the subjects concerned. This paper, after performing systematic review (SLR) to identify existing models for process assessments, provides methodology, based analytic hierarchy (AHP) method, choosing assessment model be used given application (process, product, or service). For SLR, papers from databases Scopus, Web Science and Direct were used. Forty articles considered this study,...

Thermal spraying (TS) is one of the main processes for obtaining surfaces with desired protective properties in various industrial applications. TS an energy-intensive treatment required to heat application material and consumes different resources. To assess environmental impact TS, it becomes necessary integrate approach that jointly analyses evaluates economic variables influencing system. The concept eco-efficiency (EE) added process allows assessing condition through survey...

Abstract Stellite 6 is a widely applied hardfacing alloy with good corrosion and wear resistance. Several different techniques have been used to deposit this alloy, like oxyacetylene, Tungsten Inert Gas welding overlay, CO2 laser cladding thermal spray methods. This paper evaluates the resistance of coatings by high velocity oxygen fuel (HVOF) spraying gas tungsten arc (GTAW) hot wire technique. Mechanical properties microstructural characteristics are assessed compared. The influence these...

Abstract Plasma sprayed thermal barrier coatings (TBCs) have been extensively employed in most aerospace and land based turbine engines, permitting gas temperatures to be raised substantially above those for uncoated systems. Traditional TBC systems are composed of a metallic bond coat ceramic top both applied by plasma spraying. New deposition techniques proposed mainly the coat, like high-velocity oxy-fuel (HVOF) more recently cold spray (CGS). CGS is an attractive technology that...

Abstract In this study, NbC coatings, 250 µm thick, were deposited by low-velocity flame spraying on stainless steel substrates and laser remelted in a controlled argon atmosphere. Isolated passes transverse of the coatings performed at different focal lengths speeds 10, 15, 20 mm/min. Using selected parameters, layers recast with eight 10% superposition. Erosion-corrosion tests coating surfaces cross-sections characterized via SEM, EDS, XRD analysis. Modified dense, 800-µm thick no defects...

RESUMO Revestimentos são aplicados com o intuito de prolongar a vida útil componentes que operam em ambientes agressivos. material metal-cerâmico, conhecidos como cermet, WC-Co, consistem carbonetos tungstênio imersos numa matriz cobalto e utilizados materiais resistentes ao desgaste. O processo aspersão HVOF (High Velocity Oxygen Fuel) é mais adequado quando se quer obter revestimentos carbonetos. A térmica apresenta excelente qualidade relação à porosidade, dureza, resistência, densidade,...
