High corrosion resistant coating produced by PECVD and optimised for magnesium alloys

The results are a homogeneous and compact coating characterized by low porosity, which is able to protect Mg alloys from corrosion. The film, about 1000nm thick, is free from SiOH groups and with an organic fraction, which is below the detection limit of FTIR. The coating can be deposited both in conventional parallel plate low-density reactor as well as in high-density inductively coupled system. The protective capability has been tested by means of Electrochemical Impedance Spectroscopy. Coating resistance as high as 1,6 M? cm2 have been detected.
