Abstract:

The purpose of this project is to use an alternative eco-friendly milling media for the development of eco-technologies used in the production of advanced cutting tools. For this purpose, water will be used as a milling medium instead of isohexane or acetone. The use of an aqueous milling environment would eliminate the disadvantages generated using organic media (the harmful impact on the environment and risks related to the health and safety of the work, taking into account the volatility of the flammable and toxic solvents currently used). In the previous research, we have shown the possibility of replacing the organic media used industrially with an aqueous milling media, with minimum additional operations, for compacts obtained by uniaxial pressing. The present project will focus on the development of a technology for obtaining extruded compacts, with minimum additional operations. The use of extrusion as a compaction process will allow the production of round or profiled bars, respectively tubes with large length / diameter ratio, necessary to produce drills, mills, reamers or any kind of cutting tools. The implementation of such a milling media involves certain challenges, such as oxidation of constituents during milling, but also the formation of hard agglomerates. The results of this research aim to provide the information necessary to facilitate the substitution of organic milling media with water to reduce the costs and environmental impact of WC-Co powder processing techniques.

Abstract:

The proposed research, aim to find a new approach to the preparation of amorphous Fe-based and Co-based soft magnetic powders and compacts eliminating, as much as possible, the main drawbacks of the classically prepared soft magnetic amorphous materials. The amorphous powders will be prepared by mechanical alloying. Their structural magnetic, electric, thermic characteristics will be investigated and correlated with preparation conditions. Optimisation of the mechanosynthesis process by studies concerning the influence of milling conditions (wet or dry milling, speed ratio between vials and support disk, ball to powder ratio) on the powder amorphisation and their characteristics will be performed. The substitution of B and Si by different amount of Zr and/or Ti in the (Fe, Co, Ni)75 – (B, Si)25 systems will lead to a new system to be investigate: (Fe, Co, Ni)75 – (Zr, Ti)x - (B, Si)25-x. The influence of B and Si substitution by different amount of Zr and/or Ti on structure, microstructure, magnetic characteristics, and thermal stability of the alloys will be investigated. The Fe-based and Co-based powders characterised by highest saturation magnetisation, highest permeability, lowest coercivity, highest electrical resistivity and widen supercooled liquid region will be compacted by spark plasma sintering. This technique will allow us to prepare high density amorphous soft magnetic compacts conserving the magnetic characteristics of sintered amorphous powders.

Abstract:

The main goals of this project are the synthesis of new soft magnetic compacts next to the building of a new young research team. The synthesis of new soft magnetic materials with good magnetic permeability, large magnetic induction and high electrical resistivity, which could work in middle/high frequencies, is envisaged. These will be obtained by combining the iron alloys with soft magnetic iron mixed ferrites. Composite and nanocomposite materials, powders and compacts will be synthesized by combining various techniques such as mechanosynthesis, classical sintering and spark plasma sintering. The new iron alloy/iron mixed ferrite composite materials could combine the electrical and magnetic properties of the components phases, resulting, thus, higher electrical resistivity as compared to the iron alloy and increased saturation induction and magnetic permeability as compared to the iron mixed spinel ferrites. These will lead to lower eddy current losses when the composite compacts are used in frequencies application. A very important aspect proposed in this project is the synthesis of the nanocomposite iron alloy/iron mixed ferrite type compacts from nanocomposite powders. The synthesis of this type of compacts is expected to lead to an important increase of the electrical resistivity and better magnetic permeability, assured by nanocrystalline state.
