Tribology:
• Stribeck curve testing heated lubrication samples
• Wear testing anodized coatings
• Wear testing dlc coatings
Redesigned Compact Profilometer & Mechanical Tester
The product enhancement, of both the PS50 Profilometer and Compact Mechanical Tester, showcase Nanovea’s dedication to consistent improvement. The two high-end entry level options have been redesigned with new bases to coordinate with Nanovea’s standard. The PS50 Profilometer and Compact Mechanical Tester provide accuracy and capability unmatched in each of their respective class.
Mechanical Properties of Smartphone Glass
In this study, the Nanovea Mechanical Tester is used to perform a comprehensive study of the tribo-mechanical
properties of a smartphone lens, including the hardness, Young’s modulus and fracture toughness as well as scratch and wear resistance, in order to showcase the versatility and accuracy of the Nanovea Mechanical Tester in glass sample testing.
Tribological Properties of PTFE Using Tribometer
In this application, the wear process of a PTFE coating for non-stick pan is simulated using
Nanovea Tribometer in linear reciprocating mode. In addition, the Nanovea Mechanical
Tester was used to perform a micro scratch adhesion test to determine the critical load of
the coating adhesion failure.
Seed Surface Topography Using 3D Profilometry
In this application the Nanovea ST400 Profilometer is used to measure the surface of a tomato seed and romaine lettuce seed. The entire surface of each seed was scanned with a high resolution. Various analyses will be used to characterize the surfaces
including surface roughness, contour analysis, and texture direction.
