Journal of Nanomaterials

The created scaffold is characterised by good mechanical properties, which is confirmed by the results of the performed tensile and compressive strength tests. Titanium porous skeletons are achieved by selective laser sintering SLS. The following articles are merged in Scholar. The metal injection moulding MIM is an advanced technology and not as developed as classical pressing and sintering but constantly and dynamically developing.

Journal of achievements in materials and manufacturing engineering 27 199 Email address for updates. Keynote Speech Abstract Title: Part of the book: The chapter presents the overview leszeo powder injection moulding as specialist powder metallurgy method and its application for fabrication of tool materials.

And, he has also won ca. In last part of the chapter, the results of own investigations of the structure with nanostructural elements of high-speed steels and carbide-steels on their matrix fabricated by powder injection moulding are presented. Journal of materials processing technology, The original and author technology of production of the aluminium AlMg1SiCu matrix composite materials reinforced with halloysite or carbon nanotubes using powder metallurgy techniques, including mechanical alloying and hot extrusion and the range of own research in the case to determine microstructure, as well as mechanical properties of those materials was present.

The results of the microbiological research are included in the lecture.

On the inner surface of the pores in these skeletons, the thin coatings are generated using the atomic layer deposition or sol-gel dip coating methods. Articles Cited by Co-authors. In this chapter, the characterisation of the halloysite nanotubes HNTs and multiwalled carbon nanotubes MWCNTs as the reinforcement in the composite materials was described. He is one of the 55 most frequently cited contemporary Polish scientists of all disciplines.

The infiltration technology with reinforcement in the form of porous skeletons fabricated with powder metallurgy methods has been presented in relation to the general characteristics of metal alloy matrix composite materials.

Wojciech Borek Assistant Professor Verified email at polsl. As modern manufacturing methods have been developing, the application methods of powders have changed, and they do not always have to be moulded prior to sintering.

The book presents the fundamentals and the role of powder metallurgy in contemporary technologies and the state of the art of classical powder metallurgy technologies and a general description of new variants and special and hybrid technologies used in powder metallurgy. The results of our own investigations are presented pertaining to four alternative technologies of fabrication of porous, sintered skeletons, and their structure and their key technological properties are presented.

Advances in Diverse Industrial Applications of Nanocomposites. This chapter of the book presents the basis of classical powder metallurgy technologies and discusses powder fabrication, preparation, preliminary moulding, sintering and finish treatment operations. This chapter characterises scaffolds manufactured in line with the make-to-order concept according to individual needs of each patient.

Get my own profile Cited by View all All Since Citations h-index 47 28 iindex It was investigated that the addition of carbon and halloysite nanotubes causes a significant improvement in mechanical properties of the obtained nanocomposites. The material is additionally subjected to surface treatment consisting of the deposition of atomic layers of titanium dioxide with nanometric thickness.

Grzegorz Matula Verified email at polsl. Gradient materials, whose properties change gradually according to their volume, are characterised.

Acknowledgments We would like to give warm thanks to all authors who submitted their manuscripts to this Special Issue, the editors who have spent their time selecting reviewers and leszeo editorial decisions, and of course the reviewers for providing their expert opinions. A general description of the materials and products manufactured with the classical powder metallurgy methods is presented. Investigations are described for four-layer materials, where the successive transition layers with a smaller and smaller volume fraction of tungsten carbide were constituted from the surface layer side, until a substrate layer containing high-speed HS steel only.
