The paper is devoted to an assessment of the mechanical behavior of hard and superhard nanocomposite coatings from loading/unloading curves measured by a computer-controlled Fischerscope H 100 microhardness tester and a maximum depth d max of the diamond indenter impression into the coating at a given load L.It is shown that (1) the area between the loading/unloading curve and theRelation between mechanical microhardness and impedance Jan 01,2004 Relation between mechanical microhardness and impedance#0183;The impedance variation of the aluminum specimen is very small,but the same is with the micro hardness.Therefore a relation between micro hardness and impedance or conductivity can be confirmed.The results are similar for the steel samples.The impedance diagram shows a good selectivity to the different structures obtained for each treated Relation between cyclic deformation mechanisms and 2.2% between 40 cycles and failure at 3324 cycles.For the indentation modulus (EIT),the standard deviation is lower than 2%,too.Similarly to the microhardness,the modulus follows the same tendency with variations of 3.5% between 1 cycle and 40 cycles and 5.8% between 40 cycles and failure.
