Estudio de la resistencia a fatiga térmica en moldes de inyección de aluminio utilizando aceros de alta conductividad térmica
(2013)
Text en actes de congrés
Accés obertLa mayoría de los mecanismos de fallo que determinan la durabilidad de un molde de inyección de aluminio a alta presión están relacionados con las solicitaciones termo-mecánicas de la superficie. En cada ciclo, la ... -
High temperature scratch testing of hard PVD coatings deposited on surface treated tool steel
(2014-09-15)
Article
Accés obertScratch testing is one of the most usual characterisation techniques for systems with thin hard coatings. Scratch tests are performed at run at room temperature, due to the risk of degradation of the indenter diamond tip ... -
Mechanical performance of AlCrSiN and AlTiSiN coatings on inconel and steel substrates after thermal treatments
