The powder injection moulding PIM method is suitable for large-lot and mass production; still, powder consumption is not too high. Porous skeletons made of Al2O3 aluminium are sintered reactively using blowing agents or are manufactured by ceramic injection moulding CIM from powder.

In this chapter, the characterisation of the halloysite nanotubes HNTs and multiwalled dobraznski nanotubes MWCNTs as the reinforcement in the composite materials was described. The technology is developing towards micro-MIM, that is, production of very small parts for miniaturised devices.
The material is additionally subjected to surface treatment consisting of the deposition of atomic layers of titanium dioxide with nanometric thickness. The metal injection moulding MIM is an advanced technology and not as developed as classical pressing and sintering but constantly and dynamically developing. Role of nanoscale surface treatment of the skeleton implant-scaffolds fabricated by selective laser sintering in dentistry The aim of the lecture is the presentation of the results of the investigations of the new obtained biological-engineering composite materials with microporous rigid titanium and titanium Ti6Al4V alloy skeletons manufactured by Selective Laser Sintering.

A general description of the materials and products manufactured with the classical powder metallurgy methods is presented. On the inner surface of the pores in these skeletons, the thin coatings dibrzanski generated using the atomic layer deposition or sol-gel dip coating methods.
Laser deposition, thermal spraying and detonation spraying of powders are also discussed as special methods in which powders of metals and other materials are used as raw materials. 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.
Special attention was drawn to a one-dimensional structure of the studied PVD and CVD coatings and its impact on the properties of coatings. 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.
