| titleOfInvention | Method for reinforcing locomotive and car wheels |
| abstract | FIELD: metallurgy. n SUBSTANCE: hardening is performed at 810-850°C. Tempering is performed at 450-500°C. Then, plasma treatment with plasmotron with energy density of 10 6 -10 8 W·m -2 is performed. Nitrogen is used as plasma-forming gas. Plasma treatment of tread contact surface and wheel flange surface is performed. Transformer of working flow of plasma-forming gas, which is profiled as to shape of treated surface, is used. Wheel is rotated during treatment about its axis at certain speed. Wheel rotation speed is determined as per ratio n=K·(1/D w ), where n - speed of wheel rotation about its axis, rpm; K - empirical coefficient equal to 20-2000 revolutions·mm/min; D w - diameter of treated wheel, mm. n EFFECT: increasing strength and thickness of reinforced layer; improving quality and efficiency of plasma strengthening process; simplifying the process diagram of strengthening plasma treatment. n 2 dwg, 1 ex |
