A teoretical part of the dissertation describes advantanges and the usage of each type of the tribological test, which induces real progress of the pressing process. An experimental parts describes performed experimental test according to relevant testing methods. Tests are evaluated in the mechanical properties terms on the basis of calculated coefficient of friction defined as a criterion of the test results of each method.
