SiC coatings demonstrating no erosion in accelerated aging test for 112 d at 87 °C, equivalent to about 10 years in vivo, can offer effective protection of the implants. Photovoltaic retinal prostheses with plasma-enhanced, chemically vapor deposited (PECVD) amorphous silicon carbide (SiC:H) SiC coatings exhibited effective protection from erosion during the 4 month follow-up in vivo.
