Films deposited on bare alloy significantly improve the corrosion resistance. Unexpectedly, films deposited on nitrided alloy present delamination and cracking after 16 days. We associate film failure with the presence of pores combined with a weak film/substrate interaction that allows diffusion of ions at the interface. We found that films tend to diminish the osteoblastic cell viability and the observed variations on film roughness do not improve cell viability.en-USGraphiteCorrosion resistanceArtigo publicado em periodicoO periódico Corrosion Science concede permissão para depósito do artigo no Repositório Institucional da UFOP.
