Tribological properties of unbalanced magnetron sputtered nano-scale multilayer coatings TiAlN/VN and TiAlCrYN deposited on plasma nitrided steels

Three types of nano-multilayer coatings, CrSiN, CrAlN and CrMoN, with different Si, Al and Mo contents were deposited on M42 substrates using a closed field unbalanced magnetron sputter ion plating (CFUMSIP) technique. Systematic characterization on the chemical composition, microstructure, hardness and wear properties of these multilayer coatings has been investigated using GDOES, low angle XRD, SEM, TEM, nanoindentation and wear tests. Experimental results revealed that all these three types of Cr, XN ternary coatings (X=Al, Si and Mo) are nano-multilayer structured. The CrAlN multilayer coatings showed the highest hardness and oxidation resistance among these three multilayer coatings. The CrMoN multilayer coatings exhibited the lowest friction coefficient although no appreciable improvements in wear resistance were observed as compared with the optimized CrN coatings.

In order to investigate the effect of PVD coatings on the performance of proto-type high temperature mold and to identify the best candidate thin films for Cu semi-solid processing, TiAlN/CrN multilayer coatings with various superlattice periods was synthesized using a closed field unbalanced magnetron sputtering method with separate Cr and TiAl and characteristics of these films were compared with those from TiN/CrN and AlN/CrN films in terms of microstructure, nanoindentation hardness, and oxidation test at 900 in air. TiN/CrN film showed the best mechanical properties but their oxidation resistance, the most critical property for high temperature semi-solid processing was the poorest. Therefore TiAlN films with a superlattice period of 6.1nm which has intermediate plastic deformation resistance with the best oxidation resistance were considered to be the best candidate out of three different films studied in this work.

Wear Mode

A series of a-C:H:Zr-x coatings (the x in the term a-C:H:Zr-x is the Zr target current varied in the deposition process) have been deposited on AISI M2 steel used unbalanced magnetron sputtering system (UBMS). During deposition process, different a-C:H:Zr-x topcoats were deposited by varying the Zr target current from 0.0 A to 0.5A while maintaining the remaining process conditions at the constant settings. The microstructure, adhesion and tribological properties of the a-C:H:Zr-x coatings were found to vary with the Zr content. The tribological properties of the coatings had been tested against AISI 52100 or Si3N4 counterbody under ball-on-disk point contact wear mode using an oscillating friction and wear tester. Of the various coatings, the a-C:H:Zr-0.4 coating provided the best tribological properties, including the lowest wear depth, the friction coefficient and the longest lifetime. Compare to the coatings sliding against both counterbodies, all of coatings possessed the high wear depth as sliding against Si3N4, but it displayed longer wear lifetime than sliding against AISI 52100.
