Fish Scale Surface Characterization Using 3D Profilometry
In this application the Nanovea ST400 Profilometer is used to scan the entire surface of the scale, along with a smaller higher resolution scan in the center of the scale The outer and inner side surface roughness of the scale was also measured for comparison.
Surface Characterization of Fish Scale Using 3D Profilometry
Mechanical & Tribological Properties of Carbon Fiber
Combined with the wear test by Tribometer and surface analysis by Optical 3D Profilometer, we
showcase the versatility and accuracy of the Nanovea instruments in testing composite materials
with directional mechanical properties.
Breakthrough Measurement Proven on Steel & Aluminum
For the first time, Nanovea has developed a breakthrough method of reliably acquiring both yield strength (YS) and ultimate tensile strength (UTS) through the indentation technique; which has significant advantages when compared to the traditional tensile testing. Learn more in this months updated application note.
Using Acoustic Emission (AE) During Wear Testing
During Tribometer wear testing, the constant rubbing process of the counterface against the test sample creates a series of events, such as deformation, cracking, abrasion, phase transformation and material removal. These rapid stress-releasing events are the sources of AE. A quantifiable and reliable measurement of AE can provide more insight in the wear failure mechanism. Learn more in this months application note.
Wear Testing Glass With Acoustic Emissions Monitoring
The wear behavior of three types of glass (Regular glass, Galaxy S3 glass and Sapphire coated glass) is compared in a controlled and monitored manner using the Nanovea Tribometer equipped with an AE detector. In this study, we would like to show the application of AE detection during wear and its correlation with the evolution of coefficient of friction (COF).
