RESEARCH OF TRIBOLOGICAL CHARACTERISTICS OF ADI IN CONTACT WITH MODIFICIETED MATERIALS WITH DIFFERENT COATTINGS

The existing level of application of hard coatings due to relatively high deposition temperatures is largely limited to the tool area. However, special interest deserves the possibility of applying contemporary PDV procedures for the conversion of constructional steels used for the manufacture of elements of the most varied tribomehanical sistems.Friction and wear behavior of different types of nodular cast irons in contact with carbon steel were studied. The lubricated sliding line contact was performed on the Pin and Disk tribometer. Value of wear were determined by PQ index. Pins were made of carbon steel without and with three types of coating (TiN, TiZrN, TiAIN) on the tool rake surface.
