“…According to the XRD results, all coating layers mainly compose of M 23 (C, B) 6 (M = Cr, Fe, W) carbide, M 7 C 3 (M = Cr, Fe, W) carbide, (Cr, Fe)B boride, FeB boride and FeCr. As can be seen from the XRD analysis results The size intensity and form of phases in the coating layers vary depending on the changing heat input and different solidification times [ 18 ].…”

In this study, AISI 1020 steel surface was coated in different heat inputs with (wt.-%) 50FeCrC-20FeW-30FeB powder mixture by using plasma transferred arc (PTA) welding method. The microstructure of the coated samples were investigated by using optical microscope (OM), scanning electron microscope (SEM), X-ray diffraction (XRD) and energy dispersive X-ray (EDS). The hardness was measured with micro hardness test device. The dry sliding wear and friction coefficient properties were determined using a block-on-disk type wear test device. Wear tests were performed at 19.62 N, 39.24 N, 58.86 N load and the sliding distance of 900 m. The results were shown that different microstructures formed due to the heat input change. The highest average micro hardness value was measured at 1217 HV on sample coated with low heat input. It was determined that the wear resistance decreased with increasing heat input.

“…With decreasing carbide and boride amounts in coating layer’s, the hardness was decreased. It is known that hardness has good effect on the wear resistance [ 18 ]. The wear resistance of AISI 1020 was increased with increasing sliding distance from 600 m to 900 m at 19.62 N load ( Fig 7 ).…”

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.

“…Do danas je razvijen čitav niz postupaka kojima je moguće nanositi zaštitne prevlake, a najčešće su to različiti postupci navarivanja i metalizacija. Od postupaka navarivanja mogu se izdvojiti navarivanje plazmom (Plasma Transferred Arc -PTA) i elektrolučno zavarivanje netopljivom elektrodom u zaštiti inertnog gasa (Tungsten Inert Gas -TIG) [14][15][16][17][18], pri čemu se zbog niza prednosti ističe postupak navarivanja plazmom [19].…”

IzvodDelovi mašina i konstrukcija su tokom rada izloženi delovanju agresivne radne sredine koja u kratkom vremenskom periodu može da naruši njihov integritet. U zavisnosti od radnih uslova, površina materijala može da bude izložena raznim mehanizmima oštećenja, od kojih se izdvajaju eroziona i koroziona oštećenja. Produžetak radnog veka ugroženih zona mašinskih konstrukcija moguće je izvesti različitim postupcima nanošenja zaštitnih prevlaka, a najčešće su to različiti postupci navarivanja i metalizacije. Cilj ovog rada je karakterizacija prevlake izrađene od nerđajućeg čelika klase 316L, koja je našla široku primenu u hemijskoj i petrohemijskoj industriji, nanete plazma postupkom navarivanja korišćenjem dodatnog materijala u obliku praha, na konstrukcioni čelik S235JR. U radu je izvršeno merenje tvrdoće u karakterističnim zonama prevlake i osnovnog materijala, kao i mikrostrukturna karakterizacija prevlake na optičkom i skenirajućem elektronskom mikroskopu. Takođe, izvršeno je eroziono ispitivanje prevlake promenom parametara ispitivanja, pre svega ugla nastrujavanja i brzine čestica erodenta.
