Bakul Institute of superhard material of the National Academy of Sciences of Ukraine popup.description1 Establishing patterns of synthesis of new massive materials and coatings based on MAX phases of systems (Ti, Mn, Cr, V, Mo, Nb) - (Al, Sn) - (C, N) and comprehensive study of them properties. popup.description2  The synthesis processes of massive MAX materials Ti3AlC2 (90 -94 wt.%) for sliding current collectors, as well as a number of targets (cathodes) based on MAX phases based on (Ti,Cr,V,Mo,Nb)-(Al,Sn)–C system to use as vacuum-arc and magnetron coatings were investigated. High-entropy carbide phases containing 5 metals (TiVNbMoAl1,1C2,7 and TiVCrMoAl1,1C2,7), which have microhardness according to the specified stoichiometry of 15 GPa and 18 GPa, and crack resistance at the level of 4.6 MPa·m1/2 and 3.7 MPa·m1/2 were synthesized by means of free sintering and hot pressing. It was found that vacuum-arc coating deposited from the MAX phase Ti2AlC target on the VT1-0 titanium alloy substrate, vacuum-arc coating deposited from the MAX phase (Ti0.98Nb0.02)AlC target on the OT4-1 titanium alloy substrate, and magnetron hybrid coating with simultaneous deposition of the MAX phase Ti2AlC and Cr on the OT4-1 titanium alloy substrate fully satisfy the requirements for fuel cell interconnects (solid-state SOFC and light molten carbonate fuel cells MCF). In addition, vacuum-arc coating from the MAX phase Ti2AlC target provides a 2-fold increase in the wear resistance of 15Х16К5Н2МВФАБ-Ш steel and BT8 titanium alloy at 500 °C, as well as an almost 5-fold increase in the resistance of these alloys to multi-cycle fretting fatigue.
