Fracture Resistance of Silicon With Nano Scratch Testing

In this application, the Nanovea Mechanical Tester, in nano scratch testing mode, is used to measure the fracture resistance of a 170μm thick silicon sample. We must simulate the process of scratching in a controlled and monitored manner to observe sample behavior effects.  A 2μm diamond tipped stylus is used at a progressive load ranging from 0.5 mN to 400 mN to scratch the silicon surface. Points of failure will be reviewed.

Nano Puncture Resistance Using Nanoindentation

In this application, the Nanovea Mechanical Tester, in Nanoindentation mode is used to study the puncture resistance of an aluminum foil sample using a cylindrical flat tip indenter. A custom sample holder was designed to secure thin film and foil samples.

Tablet Coating Failure With Micro Scratch Testing

In this application, the Nanovea Mechanical Tester, in its micro scratch mode, is used to measure the load required to cause the failure to a generic and brand tablet coating. We must simulate the process of scratching in a controlled and monitored manner to observe sample behavior effects. A 20μm diamond tipped stylus is used at a progressive load ranging from 4 N to 8 N to scratch the tablet coating. The point where the coating fails by cracking is taken as the point of failure. Hardness and elastic modulus will also be evaluated in nanoindentation mode.

Roughness Measurement of Pill Using 3D Profilometry

In this application, the ST400 Profilometer is used to measure and compare surface roughness measurement values of different types of tablets. Excedrin, Advil, and generic forms of Excedrin and Advil, distributed by SUPERVALU Inc., are the tablets measured in this application. Comparisons can be made between generic and name brand tablet surface roughness, between coated and uncoated tablet surface roughness, and also among the same type of tablet to check the variations in surface roughness, mainly through the standard deviation.

Surface Area Measurement of Oxidation With 3D Profilometry

The 3D Non Contact Profilometer will be used to characterize the surface area measurement of two samples with A1SiN coatings, one with a low level of silicon the other with a high level. The A1SiN coating was deposited on H13 Steel by magnetron sputtering then submitted to an oxidation resistance test (900°C-1hour).

Tribological Characterization of Ti-WS2 Coating

In this report we will review the tribological characterization of Ti-WS2 coating deposited by Magnetron Sputtering technique. The friction and wear tribology will be obtained with the Tribometer in reciprocating mode and an integrated optical profiler will be used to obtain wear rate.

Scratch Resistance of Microstructure using Scratch Testing

In this application, the Nanovea Mechanical Tester in its nano scratch testing mode is used to measure the load required to cause failure to a microstructure. We must simulate the process of scratching in a controlled and monitored manner to observe scratch resistance. A 10μm diamond tipped stylus is used at a progressive load ranging from 10 mN to 20 mN to scratch the microstructure. The point where the coating fails by cracking is taken as the point of failure.

Connector Pin Inspection With 3D Profilometry

In this application, the Nanovea ST400 Profilometer is used to measure the full area of a connector surface and its pins. The application was chosen for its challenging features while highlighting the measurement options with Nanovea’s technique. There is an endless list surface parameters that can be automatically calculated after the surface scan. Here we will review a full 3D profile, flatness of the connector base, coplanarity of the pins and the roughness of a pin tip.
