LTC20068, 15. 5. 2020–26. 2. 2023

Annotation: The project aim is an extensive research on the employment of mechanochemical synthetic approach for the production of metal matrix nanocomposite powders based on Mo and reinforced with rare-earths oxide phases for reduction of ductile-to-brittle transition temperature and improvement of high temperature oxidation behaviour. This aim will be achieved by applying solid-solid (ex-situ) and liquid-solid (in-situ) composite powder synthetic strategies, utilizing the high energy kinetic milling, reactive kinetic milling, mechanochemistry and chemistry. In the ex-situ study the ultrafine powders of rare-earths oxide phases (mainly based on La, Gd, and Ce oxides and zirconates) will be synthetized via sol-gel techniques or mechanochemical syntheses, and in a secondary phase they will be milled with the commercially available Mo metal powders using high-energy ball milling. The role of milled powder chemistry as well as the effects of technological parameters, i.e. milling speed, milling time, milling temperature, milling atmosphere, milling media, ball-to-powder ratio and process control agents on reduction of powder particle size, rare-earth oxide or zirconates particle distribution at the metal grain boundaries, and its influence on alloying or phase transformation will be investigated. The in-situ study will focus on processing, reaction mechanisms and technological parameters with the aim to obtain composite reinforcement with rare-earth oxide/zirconate phases directly from the reagents mixed with Mo metal powders in high-energy ball mill. Both powders, produced by ex-situ and in-situ methods will be studied by the means of available techniques widely used in materials science.

FV40099, 1. 4. 2019–31. 12. 2020

Annotation: The project focuses on the development of specific single-purpose machining centre dedicated to processing and monitoring of highly accurate and complex-shape grinding tools made from modern abrasive materials and utilized especially in automotive and aviation industries, where high demands on quality and dimension control of grinding tools are of critical importance. New machining centre will have modern control elements linked to automatic evaluation of dimensions after the machining. The current machining process in the applicant’s company is carried out by a number of individual machines, which are used for the final machining of grinding tools. Up-to-date machining of complex grinding tools is accomplished utilizing at least four separate machines, where individual surfaces of the grinding tool are processed. However, this method of manufacturing of geometrically complex grinding tools is ineffective in terms of expended and personal costs, time and energy. For these reasons, the project aims on automation of whole machining process. Furthermore, project will cover not only the development of the machining centre itself, but also the automation of the input and output control mechanisms, which will evaluate the technical parameters and materials of the grinding tools. The project will be solved in the production area of Best – Business company, which is a traditional producer of abrasive tools, materials and heat-resistant products, in partnership with the Central European Institute of Technology – Brno University of Technology, and the Center of Progressive Technologies. New single-purpose machining centre will have a major impact on the quality, precision, reproducibility and final price of the highly accurate and complex-shape grinding tools, and thus will significantly strengthen the competitiveness of the Czech medium-sized company of project coordinator at the national and international markets.

Structural biodebradable implants processing by means of direct metal laser sintering

FV20232, 1. 7. 2017–30. 6. 2021

Annotation: The main objective of the project is development and production of innovative biodegradable porous bone void fillers. Material used for production of such implants will be magnesium alloy WE43, which exhibits good biocompatibility. Mechanical properties of the alloy are close to those of bone tissue and implants from such alloy can therefore provide sufficient support to the healing tissue without undesirable stress shielding effect. Implants from such alloy also exhibit osteoinductive properties and its degradation promotes bone tissue healing process. The implant is gradually resorbed by organism during healing process providing support. After the healing process ends, no metal residues are left in the body and there is no need for costly operation for implant removal. Application of biodegradable implants is therefore less invasive, comparing to commonly used bioinert materials. For cell adhesion to the implant, not only implant material type or its surface treatment is important, but also state of the implant surface. Therefore, bulk and porous implants as well as implants with bulk core and porous surface layer will be tested. For the production of implants, selective laser melting method will be used. Such progressive method allows not only production of complicated shapes but also control of porosity of final component. Alternatively, CaP based surface treatments and their influence on corrosion properties and biocompatibility of the whole implant will be tested.
