On this basis, a new design of the tram pantograph is developed. A MAX phases Ti3AlC2 and Ti2AlC based coating on a thin (0.3… 0.5 mm) titanium sheet to replace of chromium type Crofer steel sheets, when creating light connecting elements with high characteristics of heat resistance and electrical conductivity for solid oxide fuel cells, is proposed. It was found that the welded joints of the strengthened D16T alloy, obtained by the pulse-arc method with the fusible electrode Sv-1201 and subsequent joint quenching and aging, are not inferior in comparison with AMg6 alloy welded joints. The highest strength and fatigue crack resistance of characteristics of D16T alloy joints (not lower than the properties of the base metal) are achieved by using stir friction welding, when there are no decay and coagulation of the reinforcing intermetallic phase of the base metal. The possibility of the microdamages accumulation monitoring on the early fatigue stages (incubation period of microcracks, period of system formation and critical number of microcracks, incubation period of macrocrack formation and growth) of the system Al-Cu-Mg aluminum alloy based on the analysis of the acoustic emission signals parameters is revealed. New multi-component eddy-current devices for single-channel control systems have been developed, which increase the non-destructive control sensitivity and productivity, when detecting cracks in large forgings and welded structures made of ferromagnetic and non-magnetic (austenitic) steels.
