Stylometer
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.
