1. The method of thermal spraying for coating in the groove (2) for the piston ring of the piston (1) of a two-stroke diesel engine of high power, and for the reception and direction of the piston ring (3) in the groove (2) for the piston ring, this groove (2) is limited the first side surface (21) close to the combustion chamber, the second side surface (22) farthest from the combustion chamber and the circumferential rear surface (23) made in the piston side surface (100), characterized in that at least the first side surface (21) and / or second b the casing surface (22) of the groove (2) for the piston ring is provided with a thermally sprayed coating (4) by a method of thermal spraying of wire. ! 2. The method according to claim 1, characterized in that the thermally sprayed coating (4) is a wear-resistant coating (4). ! 3. The method according to claim 1 or 2, characterized in that the method of spraying the wire is a method of flame spraying the wire, a method of plasma spraying the wire, in particular, a method of electric arc spraying of wire. ! 4. The method according to claim 2, characterized in that the flux-cored welding wire (5) is used as a spray wire (5), in particular, a flux-cored welding wire (5) filled with nanoparticles and / or an amorphous phase and / or solid phase is used . ! 5. The method according to claim 2, characterized in that the sprayed wire (5) consists of elements C, Cr, Mn, Mo, B, W, Nb, Si and Fe. ! 6. The method according to claim 2, characterized in that the sprayed wire (5) has the following composition:! C = 2-6 wt.%! Cr = 10-30 wt.%! Mn = 2.5-7.5 wt.%! Mo = 5-15 wt.%! B = 2.5-7.5 wt.%!
