“…The experimental nanoindentation test is performed in load or depth controlled mode using a Nano Test System [3,2]. Diamond (E = 1141 MPa, ν = 0.07), Berkovich pyramid (tip radius R = 150 nm, pyramid angle α = 70.32°) penetrates into the specimen.…”

“…The first objective of the work was investigation of properties of tribological hard nanocoatings system, which is composed of TiAlN [3] and TiN [2]. These materials are deposited on the elastic substrate like carbide using PVD technique.…”

“…Repetitive scratch tests can also be informative at the micro-scale, typically using 25 µm end radius diamond probes in conjunction with applied load in the range 0.5-5 N. Beake and Ranganathan used this approach to investigate the low cycle fatigue behaviour of mono-, bi-and tri-layer hard coatings deposited on WC-Co by CVD [59]. They found a strong influence of the total coating thickness on the micro-scratch and micro-wear behaviour.…”

“…Así para un indentador Berkovich (figura 2a), el área A viene dada por la siguiente expresión. [2] mientras que para un indentador esférico (figura 2b) de radio R i , la expresión correspondiente es: [3] El módulo elástico compuesto, E * , se puede relacionar con el módulo elástico del material a través de la siguiente expresión: [4] en la que E y E i son el módulo elástico del material y del indentador de diamante (1.140 GPa) respectivamente, y υ y υ i son los coeficientes de Poisson del material y del indentador (0,07), respectivamente. La dureza del material se puede calcular dividiendo la carga máxima entre el área de contacto proyectada: [5] Es bien conocido que la dureza aparente de un material puede ser función de la carga máxima aplicada durante el ensayo.…”
