The coatings are evaporated onto a variety of cutting tools, dies and moulds, wear components and consumer products made of high speed steel, tungsten carbide and other materials for a temperature range between 180°C up to 500° C. Hybrid PVD technologies and equipment involve cathodic arc evaporation, magnetron sputteringand HIPIMS.
PVD Coating Center, incl. technology, main and peripheral equipment and all required infrastructure for implementation of TTZH coating services in industry. PVD equipment enables deposition of high performance metallurgical coatings, such as titanium nitride (TiN), titanium carbo-nitride (TiC,N) and aluminium titanium nitride (AlTiN), aluminium chromium nitride (AlCrN), Si — doped coatings (TiSiN, AlTiSiN, AlCrSiN, AlTiCrSiN), solid lubricants, etc. for various tribology applications.

3D surface profilometry. A cosmetic application
Analysis of wrinkles on skin samples using hypoallergic silicon replicas
Non-contact surface profilometry. Effect of anti-wrinkle cream on the surface texture
Week 1 Week 2 Week 3
The cream applied has not change the number of wrinkles (mean density of furrows equivalent) but it has reduced the depth of the wrinkles (mean and maximum values)
The analysis of the main wrinkle shows not only a reduction of the depth but also a decrease of the estimated volume of the wrinkle

Tribotesting: between reality and simulation conditions
Problem with Tribology
Friction and wear are not intrinsic material properties but areproperties of the system in which the materials operate
Properties measured in an experiment using a test machine are alsoa system propertiesata generated from any properly calibrated test Data generated from any properly calibrated test machine has to bevalid, but only for the performance of the materials in that machine

Tribotesting: between reality and simulation conditions
Correlation Criterion
The test should reproduce the wear and/or failure mechanisms ofthe application
rly calibrated testIf the wear and/or failure mechanism in the laboratory emulationis not the same as the wear and/or failure mechanism in the real system,the test model is probably wrong

ROLL STABILITY TESTSStandard: ASTM D 1831
Lubricating grease is undergone to stresses similar to those in the ball bearings.Cone penetration acc. to ISO 2137 reveal changes in the shear stability of the lubricating grease and allow an assessment of its-durability-determine the oil separation-change in consistency.Depending on the test programme the typical duration of the tests could be 2 h, 50 h, 100 h.
Standard testing temperature 80°C
For greases with a density of 0,9 g/cm3 filling quantity is 55 cm3 or 50 g
