Abstract
This paper provides an overview on the recent development of coatings and modified surfaces to minimize wear between
contact surfaces in high-temperature working environments. The aim of this work was to study the wear of various types of coatings
deposited by the PVD (Physical Vapour Deposition) method on TiB2/Ti composites manufactured by Spark Plasma Sintering (SPS).
The following coatings were investigated: TiN-TiCrN-AlCrN-AlCrTiN/Si3N4-multilayer, TiN-TiCrN-AlCrN-AlCrTiN/Si3N4-
AlCrTiSiN+grad ON, TiN-TiCrN-AlCrN-AlTiCrN and as a reference, a commercially available AlCrN-based coating – all intended
to fulfil complex requirements of high-temperature working conditions. The wear tests were performed by means of a ball-on-disc
SRV friction and wear tester using reciprocating motion of the Si3N4 ball sliding against a coated disc in a wide range of temperatures
from room temperature up to 900 °C. The results confirmed that high-temperature wear resistance depends on the proper design of
the coatings.
