Interference-Based Chromatic Coatings by Ion Plating Plasma Assisted Deposition Technology
2010
The goal of replacing widespread and inexpensive galvanic treatments with suitable vacuum deposition techniques, in order to eliminate the environmental hazards and their polluting effects, is becoming, in some cases, more tangible. Shorter cleaning cycles, shorter pump-down times, reduced heating times of substrates and higher deposition rates allow the costs of new plasma-assisted processes to become competitive with respect to galvanic ones. Moreover, vacuum treatments offer superior mechanical and optical properties and non-conductive substrates (like glass, ceramics, plastics) can be more easily coated. This work describes the results obtained with Ion Plating Plasma Assisted depositio…
New Cost Effective Titanium Based Protective and Decorative Coatings by Ion Plating Plasma Assisted IPPA
2009
The activity aiming to replace galvanic treatments by vacuum processes is based on the effort to reduce the production costs and to set-up new decorative effects impossible to be galvanically realised because the use of dielectric materials. This work describes cost effective metal-oxide and oxide-metal-oxide decorative coatings based on the use of titanium as basic material deposited by Ion Plating Plasma Assisted from Reactive Magnetron Sputtering source. A new multilayer protective and decorative structure, based on the use of titanium and titanium oxides is also presented. The protective effect against aggressive environment is obtained by alternating layers of metal and metal-oxide mix…
Cost Effective Treatments to Replace Galvanic Processes
2009
Some of the most severe problems in the replacement of galvanic treatment with PVD coatings reside, first of all, in the higher costs of vacuum processes and in the difficulty to coat many 3D small samples. This work describes the results obtained by using energetic deposition vacuum processes, of the family of Ion Plating Plasma Assisted (IPPA), using both thermal and sputtering sources, able to reduce dramatically the duration of deposition process and to eliminate the substrate heating and their pre-cleaning. Regarding the small 3D samples, an innovative structure, named "Ionic Rotarybarrel" is presented. The realised treatments are in the fields of decorative, protective and tribologica…
