For Vickers hardness determination, the indentations were made using a pyramidal diamond indenter
(Mitutoyo, MHV H-2) with an applied load of 200g.
15 for friction between the diamond indenter
and metallic materials was used throughout this study; and large deformation FEM computation was performed.
Near a visible registration mark, scratches or indentations were created on coating surfaces using Hysitron TriboIndentor[R] with a Berkovich diamond indenter
of tip radius R [Less than] 100 nm, all with a peak force of 400 [mu]N.
Because some of the indentation loads were very small, their resulting indentation depths were also very low and at low depths the influence of the tip geometry of the diamond indenter
on the diamond area function was included in the analysis step.
A Berkovich (three-side pyramidal) diamond indenter
was used throughout the experiments in order to determine the nanohardness of specimens both inside and outside the wear tracks.
Hardness testing, one of the most common and widely used destructive testing methods, is performed by forcing a hard ball or diamond indenter
into the surface of a casting.
The indentation process of pressing a Rockwell diamond indenter
into inelastic material has been studied to provide a means for the analysis, simulation and prediction of Rockwell hardness tests.
For example, the diamond indenter
itself affects the hardness by creating defects in the material, Cohen says.
In the PLST, a diamond indenter
is drawn across the coating surface under a load that is continuously increased until the coating detaches from the track.
The intender tip was a three-sided pyramidal diamond indenter
, known as a Berkovich indenter, whose geometry was determined using atomic force microscopy.
with a pyramidal Berkovich diamond indenter
(radius of the indenter tip: 0.
For this study, the DMA was equipped with a diamond indenter
and used in a static stress scan mode (no dynamic component) to measure modulus from mN load indent analysis.
