Usually they are called hard material when the hardness is around 20 GPa, superhard with a hardness of 40 GPa and ultra-hard materials when is 80 GPa [2].
Materials and Methods The coatings were deposited through CAE – PVD technology with a Platit 1001 coating system equipped with 4 cathodes (2 Cr, AlTi 50/50, AlTi 63/37) in high vacuum (10-4 mbar) with a positive pressure of 102 mbar of N2 thus the operative total pressure in the chamber during coating was 10-2 mbar.

Introduction
Cu-Al2O3 particulate reinforced composites have gained, in recent years, a great interest for the high potential of use in numerous applications as substitutes for traditional materials [1].
Experimental conditions Electrolytic copper powders of 99.7 % purity and Al2O3 powders having particle sizes less than 63µm and α Al2O3 of 99.6 %, purity were selected as starting materials and four reinforcing levels (5.0, 10.0, 15.0 and 20.0 vol.% Al2O3) for the investigated composites.
Conclusions The above presented research results prove the possibility to obtain, by the classical routes of powder metallurgy, Cu-Al2O3 composite materials of a compactness of over 94 %.

Advanced materials and techniques all have their very specific temperature-place-time function
T = (r,z,t) [4] but conventional furnaces - even the most sophisticated ones - have serious
limitations on that function.
The superhigh temperature (ST) version has somewhat different parameters (only fourteen zones) since primarily it is designed for materials testing.
Temperature gradient and translation speed values are highly depend on the process temperature, sample size and materials used inside the cartridge.
Various materials like semiconductors, superalloys and shape memory alloys with very different technological parameters were grown successfully without any modification on the hardware [4].
