It is a very strong, stiff and hard wearing fabric (Razzaque 2004).
Tough coated hard particles (TCHP) are a new microstructure opportunity for designing hard, wear resistant materials at the particle level.
This means that, although the primary material is paper, the result is very hard wearing and practical to wear as a piece of jewellery.
Titanium nitride (TiN) has long been used as a hard, wear resistant coating material, but it has never been regarded as a low friction material.
This makes it a lot harder wearing in wet conditions.
These alloys can be used as thermo-resistant and hard-wearing materials [1, 2] and as alternatives to chromium coatings [3].
Considering that the trend is to increase the combustion pressure, new materials of lower weight, harder, wear and corrosion resistant, and compatible with the fuel environment, are needed.
Electroless nickel phosphorus coatings (NiPx) are today the hardest, most wear resistant material enabling optical surface qualities with diamond tools.
For machining abrasive materials the hard, wear resistant diamond films must be of good quality (roughness, homogeneity, crystallinity, structure) and show strong adhesion to the substrate.
However, the material itself is not hard wear-resistant, so most of the research has focused on adding V into hard nitride coatings that could lead to the formation of a self-lubricating V2O5 layer when heated.
Hardness, oxidation resistance and adhesion have traditionally been the most important parameters for material selection and optimization of hard, wear resistant coatings.
