| DEFINITION
The Stylometer is a software
driven Diamond Scratch Coating Adherence
Tester. It is intended for the testing of all kinds
of thin films and is especially valuable in the testing
of Tribiological or Wear Coatings whose adherence
normally exceeds the measurement range of
all other known adherence test instruments.
A spherical diamond is pressed against a coating
surface at a constant rate of loading as the sample
moves at a constant rate of travel. Force is
increased until the coating catastrophically fails.
The failure force is a measure of relative adherence
for samples of similar character and thickness.
It is believed that techniques can be developed
to measure coating tensile strength, elastic limit,
scratch resistance, friction coefficient and other
physical properties. |
