    (Technická Univerzita v Liberci, 2008-01-01) Čábelová, Kateřina; Solfronk, Pavel
    The topic of this graduation thesis is to compare the influence of size of contact area on friction factor during tribological testing. The work is divided into several sections. The first section describes in details the terms used within the work. The next sub-section describes methods of production of material (sheet metal), which has been tested within the frame of elaboration of this work. As it is necessary to use different lubricants, a brief survey of lubricants currently on market is presented for illustration. The work contains material safety data sheets of the lubricants used. The next part describes the methods of tribological testing. The theoretical chapter is followed by the chapter containing the description of the experiment-selection of the methods of measuring, parameters, method of preparation of samples, and the description of the measuring itself. This chapter contains the tables and graphs of the measured values. The last chapter contains a summary, where the reader can find the evaluation of measured results and the summary evaluation of the testing.
