Resumen:
A hybrid organic-inorganic sol-gel coating with the addition ofwollastonite particles is used as a potential solution to improve performance oflow cost AISI 316L stainless steel. This work is focused on characterising thecoatings by studying their synthesis and deposition, electrochemical, and invitro and in vivo response. The coated implants presented in vitro Ca/P-richapatitic precursors phases on their surface and acceptable electrochemicalbehaviour. The in vivo response regarding bone formation seems to be excellenteither with the implant in contact with bone marrow, in contact with theendostium or in contact with the trabecular bone. The bioactive andregenerative responses of bone tissue to the TEOS-MTES-wollastonite systemover-compensate the coating deterioration reaction, making these coatings as agood way to improve osseo-integration of stainless steel for long term useimplants.
