Hardness measurements of Ti and TiC multilayers: a model

Modification of composite hardness models to incorporate indentation size effects in thin films

“…Some attempts have been made to modify the composite hardness models to incorporate the indentation size effect [8,9,11,26,27] but these have all been based on the use of a either Meyer's power law [28] or Thomas' law [29], neither of which have a physical basis.…”

The influence of structure changes in the properties of TiCxOy decorative thin films

“…They show metallic as well as covalent and ionic properties, exhibiting a unique combination of characteristics that allow them to be serious candidates for a wide range of hightechnology applications [1][2][3][4][5][6]. Beyond these technological applications that can range from several examples in metallurgy, aeronautics, electronics and medicine, used to protect and to decrease wear in a variety of components, there is also the more specific case of fundamental research, where these carbides have been revealed to be a subject of great interest [7,8].…”

“…Beyond these technological applications that can range from several examples in metallurgy, aeronautics, electronics and medicine, used to protect and to decrease wear in a variety of components, there is also the more specific case of fundamental research, where these carbides have been revealed to be a subject of great interest [7,8]. The wide structural features revealed with, for instance, the variation of the C content, is one of the factor that is interesting for the research teams [1][2][3][4][5][6]. While exhibiting a number of unusual properties, most applications of the transition-metal carbides rely upon their extreme hardness, which are typically found for covalent crystals [9].…”

Determination of mechanical properties of thermally grown oxide on Fecralloy by nano-indentation

“…The effect of the substrate on the hardness of a thin film has been studied by many researchers [7][8][9][14][15][16][17][18]. Jonsson and Hogmark (J-H) used a simple approach to separate the contributions of the substrate from the measured hardness [7].…”
