Abstract

The manganes(III) complex functionalised with 2,3-dihydropyridazine has been encapsulated in the supercages of the NaY zeolite using two different procedures, flexible ligand and in situ complex. The parent zeolite and the encapsulated manganese(III) complexes were screened as catalysts for styrene oxidation by using t-BOOH as the oxygen source in acetonitrile. Under the optimized conditions, the catalysts exhibited moderate activity with high selectivity to benzaldehyde

Abstract

The welding of alloy steels in practice is a difficult process in order to achieve mechanically or chemically resistant high-quality welds. In some cases, the weldability of many materials can be difficult or is not recommended because of poor and unsuitable properties of welded joints. In our research work, we investigate the selection of an appropriate welding method for welding the manganese steel HS 20 used at dynamically strained components in the car industry. The welding methods have been selected from accessible methods of the KARRER, s.r.o. Tovarníky industrial plant. Based on the comparable welding technologies MMA, MIG/ MAG and TIG, we tested and verified the quality of welds by means of selected weld tests. The quality of these welds, obtained by the abovementioned methods, was evaluated by weld tests in laboratory conditions of the Department of Quality and Engineering Technologies (Slovak University of Agriculture in Nitra) in cooperation with NDB, s.r.o. Bratislava and SES Tlmače, a.s. The aim of the research work is to set the most suitable and effective method of welding for given components from all the technologies available in the mentioned industrial plant. Based on relevant information, we also want to enrich the scope of knowledge about welding of manganese materials in order to make the welding process more effective.
