The application of Ion Plating Plasma Assisted technology in the field of preservation of Cultural Heritage is presented. In order to guaranty the preservation of the artistic and cultural identity of ancient ceramic tiles with strong chromatic valence, not-invasive, and achromatic and antireflective coating deposition processes have been investigated. Different ceramic supports have been utilized for the tests: an ancient tile of the XIX century and contemporaneous production tiles, all characterized by strong chromatic valence and by a mixed porous and glazed surfaces. Ion Plating Plasma Assisted (IPPA) by reactive magnetron sputtering source with Argon and Oxygen atmosphere for TiO2 and IPPA by thermal source with Argon and Oxygen from SiO material have been adopted. Preliminary tests with two plasma treatments were carried out on contemporaneous tile samples in order to find the optimal processing conditions. TiO2 treatment has generated discoloration on the surface of the coating while the SiO2 coating showed achromatic and transparency properties. The ancient historical tile was used to finally test the optimized process with SiO2. Traditional organic resin spray coating treatments have been carried out for aesthetical comparative purposes with the new plasma treatment.

Abstract
The application of Ion Plating Plasma Assisted technology in the field of preservation of Cultural Heritage is presented. In order to guaranty the preservation of the artistic and cultural identity of ancient ceramic tiles with strong chromatic valence, not-invasive, and achromatic and antireflective coating deposition processes have been investigated. Different ceramic supports have been utilized for the tests: an ancient tile of the XIX century and contemporaneous production tiles, all characterized by strong chromatic valence and by a mixed porous and glazed surfaces. Ion Plating Plasma Assisted (IPPA) by reactive magnetron sputtering source with Argon and Oxygen atmosphere for TiO2 and IPPA by thermal source with Argon and Oxygen from SiO material have been adopted. Preliminary tests with two plasma treatments were carried out on contemporaneous tile samples in order to find the optimal processing conditions. TiO2 treatment has generated discoloration on the surface of the coating while the SiO2 coating showed achromatic and transparency properties. The ancient historical tile was used to finally test the optimized process with SiO2. Traditional organic resin spray coating treatments have been carried out for aesthetical comparative purposes with the new plasma treatment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
