PVD Coating (nACRo & ZrN-A)

nACRo Nanocomposite coating process

By deposition very different kinds of materials,the components (like Ti, Cr, Al in the first group,and Si in the other) are not mixed completely, and 2 phases are created. The nanocrystalline TiAlN- or AlCrN-grains become embedded in theamorphous SiN-matrix and the nano-composite structure develops.
Silicon increases the thoughness and decreases the internal residual stress of the coating. The increasing of the hardness is generated by the structure only, the SiN matrix enwraps the hard grains and avoids growing of their size.

Contain Si membrane, oxidation start temperature : 1,100℃.
Nano grade coating, better surface finish
Extremely high nano hardness, extremely high adhesion.
Better protection for tools, reduction of production cost.
