Thin-film micro-oxidation test

The thin film micro-oxidation test is often the method of choice for studying vegetable oils because it is simple and reproducible. The test is especially effective when thermally induced, volatility is low, and insoluble deposit formation through polymerization is to be considered rather than rates of inhibitor depletion. 

The objective of this research Is the examination of the effects of ion bombardment on the structure of thin ceramic films on ceramic substrates. The material combinations will Include oxide films that have (a) no solid solubility, (b) limited solid solubility, and (c) complete solid solubility with the substrate material (also an oxide). Techniques for determination of elastic and plastic properties of thin films or coatings on ceramic substrates and for the determination of the strength of the bond between the film and substrate, which are currently being developed, will be used to determine the hardness, elastic modulus, and adherence of each material combint tion. The main testing techniques will be the ultra-low load micro-indentation tester (Nanaindenter) and thermal cycling tests.
