The present paper describes a new method concerning the production of hybrid bevel gears using the Tailored Forming technology. The main idea of the Tailored Forming involves the creation of bi-metal workpieces using a joining process prior to the forming step and targeted treatment of the resulting joint by thermo-mechanical processing during the subsequent forming at elevated temperatures. This improves the mechanical and geometrical properties of the joining zone. The aim is to produce components with a hybrid material system, where the high-quality and expensive material is located in highly stressed areas only. When used appropriately, it is possible to reduce costs by using fewer high-performance materials than in a component made of a single material. There is also the opportunity to significantly increase performance by combining special load-tailored high-performance materials. The core of the technology consists in the material-locking coating of semi-finished parts by means of plasma-transferred-arc welding (PTA) and subsequent forming. In the presented investigations, steel cylinders made of C22.8 are first coated with the higher-quality heat-treatable steel 41Cr4 using PTA-welding and then hot-formed in a forging process. It could be shown that the applied coating can be formed successfully by hot forging processes without suffering any damage or defects and that the previous weld structure is completely transformed into a homogeneous forming-typical structure. Thus, negative thermal influences of the welding process on the microstructure are completely neutralized.

“…The use of powder as surfacing material in plasma arc powder surfacing technology can improve the freedom of alloy design and the workpieces produced by surfacing show good wear resistance, high-temperature resistance, and corrosion resistance [14][15][16]. Liu et al [17] fabricated two WC p /NiBSi coatings on stainless steel via electron beam melting (EBM) and PAW, respectively, for a comparative study. The result showed that the PAWed coating exhibited better corrosion resistance than EBMed coating, which could be attributed to the fact that the secondary WC precipitation of welding coating alleviated the intensity of localised corrosion by the galvanic cell.…”

The WC-Co composite coating was prepared on SS 316L by plasma arc welding technology. The microstructure, phase composition, and microhardness of the WC-Co composite coating were thoroughly studied. The corrosion behaviour including electrochemical corrosion, cavitation erosion, and erosion corrosion was tested. The results showed that the WC-Co coating exhibited a good metallurgical bond with the substrate. The average microhardness of the WC-Co coating reached 1785 HV, which was 9.4 times that of the SS 316L. The corrosion current density of the WC-Co composite coating was one order of magnitude lower than that of the substrate. Meanwhile, the cumulative mass loss of cavitation erosion and erosion corrosion of the WC-Co composite coating was much lower than that of the SS 316L.

“…Li et al 14 reported that the wear resistance of titanium grade 2 was significantly improved through Ni-WC based composite coating obtained by electroplating and electron beam remelting. Liu et al 15 reported the fabrication, study of microstructures and corrosion resistance of WCp/NiBSi metal matrix composite clad through Electron Beam Welding (EBW) and PTAW. It was reported that due to higher energy density in PTAW, interdendritic microstructure was observed which was completely absent in EBW cladded sample.…”

Processing of nickel-based high strength composites and alloys is a difficult and thought-provoking task. In this work, a strategy of heating through microwaves radiation is utilized to process the high strength hybrid Ni-based composite clad on SS 316L steel surface containing 15% (WC-8Co) and 5% Mo. The premixed composite powder was placed on the steel surface and irradiated with domestic microwave applicator having 2.45 GHz fixed frequency and 900 W power. The hybrid clad was successfully developed within 12–15 min of microwave exposure. The processed clad was subjected to various metallurgical and mechanical characterizations to understand the microstructures and phase changes. Microstructural analysis study revealed that the clad of ∼0.85 mm thickness was obtained and presence of dispersed reinforced particles of WC-8Co and Mo in nickel matrix were observed. Some inter-metallic phases of W2C, Ni2Mo4C, Ni4W and NiSi2 were observed in the clad. The average microhardness of the composite clad was712 ± 58 HV. The microwave processed clad exhibited a flexural strength of 852 ± 6 MPa with deformation index of 35 × 10−5 mm/N. Further, the sliding wear study revealed that the sliding velocity of 1.0 m/s favoured the formation of oxide tribo layers. The various mechanisms of wear revealed by the analysis of worn-out surfaces were abrasion, adhesion, surface pull-out and deformation of surfaces. The microwave processed clad revealed significant improvement in wear resistance in comparison to the steel substrate.
