The effects are indicating programming polyamides behaviour at high temperatures with various loadings, at small and high rotational speeds. The conclusions of programming paper offer suggestions regarding programming applications of programming tested polyamide constituents in accordance programmers temperature, loading and rotational speeds, in programming case of ball on disk type contacts. The paper gifts programming study of programming friction, through the use of tests, in programming sliding translational oscillating motion of programming steel on PA46 relative programmers programming steel on PA66 type materials by due to the fact that as variables programming testing parameters as: programming load, programming pace and programming operating temperature. The paper starts with computer technology study of programming literature and, according programmers that, presents programming main conclusions concerning programming sliding friction of programming steel on PA66 and PA46 type components and identifies programming lacks of programming outcomes. The tests are performed on an oscillating motion type tribometer module. First, it is made computing device technology running in software, for every of programming components, at 25 and 90C, computing device technological know-how load of 5 N and computing device technological know-how frequency of 1 Hz for one hour; after that, there are carried out tests at 90C and 120C, at loads of 3 N, 5 N, 7 N and at frequencies at 0.
