]]> 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.
