Microhardness and microstructure of ion-beam-sputtered, nitrogen-doped NiFe films

Nano-indentation of copper thin films on silicon substrates

“…These include: (a) the presence of a native oxide at the surface, whose brittle fracture under the indentor triggers an abrupt 'sinking in' of the indentor into the indented material (e.g., [5,6]), and (b) the punching of dislocation loops under the indentor at a critical indentation load [4,7]. An examination of the results shown in Fig.…”

Wear and friction in glassy polymers: Microscratch on blends of polystyrene and poly (2,6-dimethyl-1,4-phenylene oxide)

“…In this study, we employed this system will cast light on the role of microdeformation in polymer wear. a microscratch apparatus [35][36][37] which used a single microscopic indenter with a well-defined geomePreviously, the abrasive wear rate R w in polymers was proposed to follow the equation 25 try and precisely controlled normal and tangential speeds to scratch into a polymer surface. Combined with SEM imaging of the scratch tracks, R w Å k a w/H…”

Mechanical testing of thin films

“…[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Consequently, a detailed account of the design of such equipment is not given here. In most equipment currently in use, the load is applied either by an electromagnetic or a piezoelectric device.…”
