Mechanical Properties of Silicon Carbide Wafer Coatings

Understanding the mechanical properties of silicon carbide wafer coatings is critical. The fabrication process for microelectronic devices can have over 300 different processing steps and can take anywhere from six to eight weeks. During this process, the wafer substrate must be able to withstand the extreme conditions of manufacturing, since a failure at any step would result in the loss of time and money. The testing of hardness, adhesion/scratch resistance and COF/wear rate of the wafer must meet certain requirements in order to survive the conditions imposed during the manufacturing and application process to insure a failure will not occur.

Biomechanical Hardness Evaluation of Tissue

The ability to accurately measure mechanical properties in the fields of Life Science has recently become an important aspect of many current studies. In some cases, understanding the mechanical properties of soft biological surfaces have helped uncover the mechanical effects of diseases. Understanding mechanical properties provides a context for identifying the local mechanical behavior linked to specific changes. It is also critical in the development of artificial bio-materials. In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the biomechanical hardness and elastic modulus of 3 separate areas of prosciutto (fat, light meat and dark meat).

Tooth Hardness Evaluation Using Nanoindentation

In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the hardness and elastic modulus of the dentin, decay and pulp of a tooth. The most critical aspect with Nanoidentation testing is securing the sample, here we took a sliced tooth and epoxy mounted leaving all three area of interest exposed for testing.
