| INNOVATTOOLS – Inovatívne prístupy k zvyšovaniu životnosti a znižovaniu energetickej náročnosti rezných nástrojov pri spracovaní dreva v lesníctve | |
| Innovative approaches to increase the lifetime and reduce the energy consumption of cutting tools in wood processing in forestry | |
| Program: | SRDA |
| Project leader: | RNDr. Džupon Miroslav, PhD. |
| Annotation: | The project will address the issue of the use of methods and procedures for the modification of cutting tools for wood processing in forestry. The result will be an increase in their lifetime and a reduction in emissions and energy consumption of forestry machinery and equipment. The main objects of research will be tools for primary wood processing, modification and processing of forestry biomass for energy purposes, such as splitting and chipping tools, tools for cross-cutting wood, etc. The main task of the project will be the design of procedures and methods for the modification of exposed functional surfaces of the tools. Ensuring a higher quality of functional tool surfaces in the context of reducing friction and eliminating adhesion, provides a prerequisite for reducing the load on machinery equipment and thus reducing emissions and energy consumption in a given production. Analyses will be carried out on the tools – FEM analysis in order to determine the stress-strain state, on the samples analysis of the state of the material in terms of physical properties, microstructure, mechanical properties and resistance to adhesive wear in wood-metal interaction and also abrasive wear. Based on the results of the analyses carried out, innovative surface treatment procedures will be proposed for the exposed functional surfaces to guarantee an increase in their functional lifetime. These will be applied to samples and laboratory tested by relevant test procedures. From the results of the laboratory tests, a selection will be made of the most appropriate non-conventional innovative procedures, which will be applied to the tools and tested on the equipment under forestry operating conditions. In doing so, it will be observed how the modifications in question affect the energy consumption of forestry machinery and equipment. Part of the project solution will be to ensure industrial-legal protection of the original solutions. |

| Annotation: | The project is focused on the restoration of functional surfaces by laser weld overlying. Innovative approaches willbe applied in the restoration of functional parts of molds for high-pressure die casting of aluminum alloys. Laserweld overlaying technology will be used for the formation of restoration layers in order to significantly reduce thenegative impact of the introduced heat on the quality of sub-weld layers. Newly designed additional materialsbased on Co, Ni, Fe with the presence of dispersed abrasion-resistant precipitates will be used. Additionalmaterials for laser welding will be used in the form of wires made of Uddeholm Dievar and Maraging. For bettervariability of the chemical composition, powder additives based on Fe with the addition of B, Ti, Nb, Mo, V and Wwill also be used to create weld overlays. The optimal method of heat treatment of weld overlays will be proposed.Research will further focus on microtexturing the surface of molded parts by low-energy laser radiation usinginnovative engraving surface treatment methods (LBT and EBT) in order to ensure a smooth distribution of theseparating agent on the mold surface. Experimental work will be focused on modifying the microgeometry of thesurface of new and renovated shaped parts of molds so that in the phase of "run-in of the mold" a compact layer ofthe separating agent is created to increase the technological life of molds. PVD and PE-CVD technologies will beused for this purpose. |

| Annotation: | The project deals with metal matrix composites made by powder metallurgy from coated, nanostructured or amorphous materials. Metals with nanostructured or amorphous reinforcements represent a relatively new and yet poorly understood class of materials. The project is oriented on fundamentals rather than on a specific composite development. The aim is to answer the questions: How is the powder-mass\’ behavior related to properties of individual coated, nanostructured or amorphous particles? What are the fundamental processes during compaction and sintering of such powders and how do they affect the product’s microstructure? What are the basic links between microstructure and macroscopic properties of metals with coated, nanostructured or amorphous reinforcements?Both experimental and theoretical means will be used to reach the project goals. Experiments combined with a theoretical study of model systems should contribute to the understanding of properties and potential of a given class of materials. |
