The choice of treatment (single or combined) is made depending on the application, the hardness, the type of steel used, the geometry and finish of the piece.
Born for this technology in aerospace applications, has proved ideal for products that need a functional coating as well as decorative, as subject to wear through friction or that used in corrosive environments. This technology is completely environmentally friendly and consistent with a source nell'evaporazione metal in a vacuum chamber.
PVD coatings are divided into the following categories:
TIN: titanium nitride
TiCN: carbonitruro Titanium
TiAlN: titanium nitride and aluminum
DLC : deposito di diamante DLC: diamond deposit
ZrN : n zirconium nitride
PVD coatings are not only of great aesthetic effect, but have exceptional functional characte They achieve hardness of 2000-2500 HV. The colors do not change over time, because oxidize at temperatures above 400 ° C, so the test gives UNI 9397 result: unlimited.
the PVD coating had a high cost and was applied to pieces with a high level. Today, thanks to new technologies can reduce production costs and have a large number of items at low cost. In Italy, many manufacturers handles, sunglasses, watches and some manufacturers of valves and pipelines have chosen to take their products using this technology.
TREATMENT PECVD This technology protects the details from wear and corrosion caused by atmospheric or chemical agents. il PECVD (plasma enhanced Chemical Vapour Deposition). The need to improve or change the surface characteristics of the particular characteristics and to obtain anti-slip and, to date fell on galvanic treatment, coating and heat treatment or chemical, now there is this new technology, PECVD (plasma enhanced Chemical Vapor Deposition ).
I Coatings produced with this technology such as DLC (Diamond Like Carbon) or SIOX (silicon oxide) can be applied on a large amount of substrates including: metals, alloys and plastics in general. Deposition that is deposited on the substrate improves the properties of the product, does not alter its morphological characteristics (roughness, brightness, etc..) Coatings and makes functional and decorative at the same time. The deposited films have a thickness of few microns and the processes occurring at room temperature for which there is no distortion or dimensional variations. DIAMANTIN DIAMANTINA
E 'coating, highly resistant.
These are amorphous carbon with diamond structure, not be challenged by the elements, organic chemicals, acidic or alkaline solutions.
