Sliding Wear Performance of AlCrN Coating on TiB<sub>2</sub>/Ti Composites at High Temperatures

The aim of the study was to investigate effect of Ti/TiB<sub>2</sub> composite composition and manufacturing technology parameters on the tribological behaviour of AlCrN coating-composite system. The AlCrN coating was deposited by PVD (Physical Vapour Deposition) method. The composites w...

The AlCrN coating was deposited by PVD (Physical Vapour Deposition) method. The composites were manufactured by spark plasma sintering (SPS) from three variants of powders mixtures: Ti with TiB<sub>2</sub>, Ti6Al4V with TiB<sub>2</sub> as well as Ti with B, using (five) different sintering temperatures. For each of the developed coating-composite systems, the wear resistance was evaluated using ball-on-disc SRV tester, at six temperatures (from room temperature up to 900 °C). The results confirmed that high-temperature wear resistance of the coating–substrate combination depends on Ti/TiB<sub>2</sub> composite composition and manufacturing technology parameters. In the case of uncoated composite, two processes manage the wear at high temperatures: cracking propagation and surface oxidation. The presence of AlCrN coating on the composite surface protects the surface against deep cracking and surface oxidation. The composites of Group I, sintered at 1250 °C from a mixture of pure Ti and TiB<sub>2</sub> (50/50 wt.% ratio) as well as Group III, sintered at 1350 °C from a mixture of pure Ti and B allow the achievement of a satisfactory surface quality, a high adhesion of the PVD coating and moderate wear at high temperatures. However, the composite made of pure Ti and B seems to be a better solution for temperatures exceeding 600 °C.Remigiusz MichalczewskiMarek KalbarczykZbigniew SłomkaEdyta Osuch-SłomkaMaciej ŁuszczLe LiuMaksim AntonovIrina HussainovaMDPI AGarticletribologysurface engineeringcoatingTiB<sub>2</sub>/Ti compositesSPSwearTechnologyTElectrical engineering.
