Text en actes de congrés
Accés obertThe mechanical behavior under contact loading of systems consisting of PVD AlCrN film deposited onto two distinct hard substrates - cemented carbides and tool steel is studied by means of indentation testing techniques, ... -
Micro and nanomecanical behavior of mullite-based environmental barrier coatings
Botero Vega, Carlos Alberto (Universitat Politècnica de Catalunya, 2012-12-14)
Tesi
Accés obertMullite coatings deposited by chemical vapor deposition (CVD) have been introduced and proven as excellent candidates to protect silicon carbide (SiC) from severe pitting corrosion and recession, becoming part of the new ... -

Nanoindentation and nanoscratch properties of mullite-based environmental barrier coatings: Influence of chemical composition - Al/Si ratio
Botero Vega, Carlos Alberto; Jiménez Piqué, Emilio; Martin, R; Kulkarni, Tushar; Sarin, Vinod K.; Llanes Pitarch, Luis Miguel (2014-01-25)
Article
Accés restringit per política de l'editorialThe mechanical properties and structural integrity of mullite (3Al2O3·2SiO2) environmental barrier coatings (EBCs) are key factors towards the implementation of these systems in real applications. By using chemical vapor ... -
Nanoscratch testing of 3Al2O3·2SiO2 EBCs: assessment of induced damage and estimation of adhesion strength
Botero Vega, Carlos Alberto; Cabezas i Peñalva, Laura; Sarin, Vinod Kumar; Llanes Pitarch, Luis Miguel; Jiménez Piqué, Emilio (2023-03-01)
Article
Accés obertn this study, the structural integrity of mullite (3Al2O3·2SiO2) films, deposited on silicon carbide (SiC) substrates using chemical vapor deposition (CVD), was investigated via increasing load nanoscratch tests. The films ...
