Purpose
This equipment
evaluates scratch resistance of materials.
Application
|
Hard surface of
metal, ceramic and composite. |
| |
Adhesion strength
of coatings. |
|
Coated parts like cutting
tools, watch cases. |
| |
Electroplated semi-conductors. |
|
Dentures. |

|
Features
|
Software controlled
operation. |
|
Multiple parallel tracks
with programmable loads, speeds and strokes.
|
|
Records traction force,
test load and acoustical emission. |
|
Stylus of various geometry
and material. |
|
Uni-directional and bi-directional
movement. |
|
Built-in image acquisition
to view and capture scratch image. |
Instrumentation and Data Acquisition system
|
On
line measurement of normal load, traction
force and acoustic emission. This data is
displayed on the controller and acquired
in PC |
| |
|
Graphs of individual tests
can be processed and printed. |
|
Results of different tests
can be superimposed. |
