| الوصف: | The dissertation investigates the created new flux-cored wires for thermal arc spraying and the properties of coatings sprayed by them. The main ob-ject of research is the new materials created for thermal arc spraying and the Fe-Mn-Cr-Mo-Ni, Fe-Mn-Cr-Mo, Fe-Mn-Cr system alloy coatings sprayed on the basis of these materials. The application area of new flux-cored wi-res created for thermal arc spraying is restaurated or produced new parts which are used in various fields of industry and agriculture. This disserta-tion aims at choosing the optimal technological spraying process and thus getting the coatings with the best mechanical, physical, tribological and an-ticorrosive properties, suitable for real exploitation conditions. The paper approaches these main tasks: influence of molten flare particles on coa-tings‘ morphology, influence of chemical composition and technological parameters on mechanical properties of coatings, corrosive and friction re-sistance under various conditions. Changing of thermal arc spraying current allowed to identify influence of particles granulometry and coatings mor-phology on mechanical and tribological properties. The experimental methods of analysis applied in work allowed to evaluate the qualitative cha-racteristics of coatings. The dissertation consists of introduction, 3 chapters, general conclu-sions, references, list of scientific publications by the author on the topic of the dissertation, and 3 annexes. The introduction reveals the investigated problem, importance of the thesis, and the object of research, and describes the purpose and tasks of the paper, research methodology, scientific novel-ty, the practical significance of results examined in the paper and defended statements. The introduction ends in presenting the author’s publications on the subject of the defended dissertation, offering the material of made pre-sentations in conferences and defining the structure of the dissertation. Chapter 1 revises used literature. It reviews the papers dealing with different ... |
