“…[2][3][4][5][6] Among these processes, GTAW cladding is one of the most promising processes because of its high deposition rate and wide applicability. [6][7][8][9] This process uses a nonconsumable tungsten electrode and an inert gas for arc shielding. An electric arc is established between the tungsten electrode and the part to be welded.…”

In this study, multicomponent alloy fillers were deposited on low-carbon steel substrates using gas tungsten arc welding (GTAW) process. The microstructure and wear properties of Al-Co-Cr-Ni-Mo-Fe-Si multicomponent alloys were studied. The GTAW cladding layers were analyzed by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), X-ray energy dispersive spectroscopy (EDS), and transmission electron microscope (TEM). The results show that the microstructure mainly consisted of dendritic FeMoSi and interdendritic BCC phases and that the addition of Si coarsened the primary FeMoSi phase. In addition, different precipitate morphologies were found in the interdendrites. As the Si content increased from 5.92 to 14.53 at%, the microhardness also increased from 826 to 885 Hv and the wear resistance improved significantly. The FeMoSi dendrites possessed covalent-dominant strong atomic bonds that enhanced the hardness and wear resistance of claddings.

“…However, its shallow weld penetration causes lesser production rate. Increase in weld passes for thick sections lead to higher input in the weld which reduces the weld strength [1] by producing the coarse grain microstructure [2].…”

“…In addition, the interface of matrix and particles is affected by the heat input. The consequence is a thermal induced damage that leads to ineligible porosities and inhomogeneities [19]. Furthermore, the formation of IMC can occur so that the properties of these joints can be insufficient [20].…”

Brazing has a long tradition at the Institute of Material Science and Engineering of the University of Chemnitz, Germany. During the last years, comprehensive and innovative knowledge in brazing and soldering technologies were generated. Originating from high-temperature brazing, topics like metal-ceramic and light metal brazing, ultrasound assisted joining processes through to brazing of metal matrix composites were examined. In addition, new topics like joining by nanoparticles or corrosion behavior of brazed heat exchangers are in the focus of research. Prof. Bernhard Wielage managed the institute for 22 years. Today, Prof. Guntram Wagner introduces new topics like friction stir welding and continues the activities in brazing.Keywords: brazing; soldering; heat exchangers; brazing of metal-ceramic joints; soldering with diamond particles StreszczenieTradycje związane z tematyką lutowania twardego w Instytucie Materiałoznawstwa i Inżynierii Uniwersytetu w Chemnitz (Niemcy) są długie. W ciągu ostatnich lat wygenerowano kompleksową i innowacyjną wiedzę dotyczącą technologii lutowania miękkiego i twardego. Zajmowano się problematyką badawczą wywodzącą się od lutowania wysokotemperaturowego, taką m.in. jak: lutowanie twarde metali lekkich z ceramiką i wspomaganie procesu spajania ultradźwiękami w lutowaniu kompozytów metalowych. Obecnie przedmiotem badań są nowe zagadnienia, takie jak: spajanie nanocząsteczkami oraz zachowanie odporności korozyjnej wymienników ciepła lutowanych na twardo. Profesor Bernhard Wielage zarządzał Instytutem przez ostatnie 22 lata. Obecnie, nowy Dyrektor Instytutu Profesor Guntram Wagner zajmuje się takimi zagadnieniami, tjak np. zgrzewaniem tarciowym z wymieszaniem materiału zgrzeiny (FSW) i kontynuuje prace badawcze związane z lutowaniem twardym.Słowa kluczowe: lutowanie twarde; lutowanie miękkie; wymienniki ciepła; lutowanie materiałów różnoimiennych metal-ceramika; lutowanie miękkie z cząstkami diamentu
