Development of a Temperature-Graded Tailored Forming Process for Hybrid Axial Bearing Washers

Abstract: The Tailored Forming process developed in the presented research enables the production of axial bearing washers with AISI 1022M (C22.8/1.0460) base material and AISI 52100 (100Cr6/1.3505) cladding on the rolling contact surface. By limiting the use of the bearing steel to the highly loaded surface, significant amounts of alloyed steel can be saved. The cladding is applied through plasma transferred arc (PTA) welding and subsequently formed to improve its properties. The challenge in developing a hot upsetting process lies in the high difference in flow stress of the two materials, since the harder bearing steel is merely pressed into the softer base without sufficient deformation. In order to equalise the flow stress of both materials, an adapted temperature gradient is induced over the washer height before upsetting. Due to this, a higher cladding temperature is set while the base material remains significantly cooler. This is realised by means of local inductive heating of the cladding and different transfer times to the upsetting process. The process variants are applied in an automated forging cell and subsequently evaluated in metallographic analysis of cross sections after welding and after forming. The results show the most favourable material properties after forming when local inductive heating of the cladding is simultaneously combined with cooling of the base material and the transfer time between the heating stage and forming is minimized.
