ΡΠΎΠΌΠ°, Π°Π»ΡΠΌΠΈΠ½ΠΈΡ ΠΈ ΡΠΈΡΠ°Π½Π°.Accelerated tests of machine parts and mechanisms such as bodies of revolution for wear resistance and contact strength were carried out on the developed installation. The prospects of using the technology for manufacturing rolling rolls by plasma surfacing with high-speed alloys are shown. The increased wear resistance of the deposited parts is explained by the production of a high-quality deposited layer during the surfacing process without cracks, pores and defects in the macro- and microstructure and a favorable structure of the main phases, which are a solid solution of Ξ±-iron, carbides and carbonitrides based on iron, tungsten, molybdenum, chromium, aluminum and titanium.ΠΠ²ΡΠΎΡΡ Π²ΡΡΠ°ΠΆΠ°ΡΡ Π±Π»Π°Π³ΠΎΠ΄Π°ΡΠ½ΠΎΡΡΡ Π»Π°Π±ΠΎΡΠ°ΡΠΎΡΠΈΠΈ ΡΠ»Π΅ΠΊΡΡΠΎΠ½Π½ΠΎΠΉ ΠΌΠΈΠΊΡΠΎΡΠΊΠΎΠΏΠΈΠΈ ΠΈ ΠΎΠ±ΡΠ°Π±ΠΎΡΠΊΠΈ ΠΈΠ·ΠΎΠ±ΡΠ°ΠΆΠ΅Π½ΠΈΠΉ Π‘ΠΈΠ±ΠΠΠ£ Π·Π° ΠΏΡΠΎΠ²Π΅Π΄Π΅Π½ΠΈΠ΅ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ ΠΌΠ°ΡΠ΅ΡΠΈΠ°Π»Π° Π½Π° ΡΠΊΠ°Π½ΠΈΡΡΡΡΠ΅ΠΌ ΡΠ»Π΅ΠΊΡΡΠΎΠ½Π½ΠΎΠΌ ΠΌΠΈΠΊΡΠΎΡΠΊΠΎΠΏΠ΅.
