Adequate measurements are of great importance for a reliable simulation and evaluation of micromechanical properties of materials and surface coatings, such as deformation or haptics. As material and coating behaviour can vary considerably, a series of proper, real-time, quantitative measurements have to be performed with high resolution in the right dimension.
UST®-Universal Surface Tester, is by far the only open multi-modular system that provides a complete mechanical testing solution for the evaluation of bulk materials and surface coatings. Its unique configuration allows for a wide range of tip choices with various materials and sizes ranging from nanometer to centimeter.
Among various kinds of commercial available in-line material property testing instruments, UST® is by far the only tester which close the gap between the traditional macro-mechanical testing machines and nanoscale machines, e.g. nano-indentator and AFMs.
One machine for all tests
Same resolution (60nm)
No need for correlation
Surface structure combined with properties
One machine for one type measurement
Need for further correlation
No record with local resolution
Point by point measurement
No surface structure vs. properties
The UST® measurement procedure consists of a mechanically scanning by a stylus on the sample surface along a straight line several times. During this patented MISTAN procedure, the stylus is moved on the surface either without load or with a defined load.
Scan with no load. Surface structure is continuously determined.
Scan on the same path with additional load to determine total deformation.
Scan on the same path with no load to determine the elastistic deformation.
Total deformation = Step 1-Step 2;
Elastic deformation = Step 3-Step 2;
Permanent deformation = Step 1-Step 3
UST®-100 with load range of 1 mN-100 mN
UST®-1000 with load range of 10 mN-1,000 mN for harder surfaces and coatings
