The possibility of tribopair lifetime extending by welding of quenched and tempered stainless steel with quenched and tempered carbon steel
In the conditions of tribocorrosion wear, extending of parts lifetime could be achieved by using stainless steel, which is hardened to sufficiently high hardness. In the tribosystem bolt/ bushing shell/ link plate oft he bucket elevator transporter conveyor machine, the previously quenched and tempered martensitic stainless steel for bolts is hardened at ≈47 HRC and welded with the quenched and tempered high yield carbon steel for bolts. Additional material, based on Cr-Ni-Mo (18/8/6) is used. The microstructure and hardness of welded samples are tested. On the tensile tester, resistance oft he welded joint is tested with a simulated experiment. Dimensional control of worn tribosystem elements was performed after six months of service.
