Abstract
In this work porous commercially pure Ti substrates fabricated by spacer-holder technique (50 vol% NH4HCO3 and three range pores sizes, 100–200 μm, 250–355 μm and 355–500 μm) were coated with two types of gelatinous materials, one as a linear polymer (non-crosslinked) and another one crosslinked. The role of the crosslink, as well as the morphology, size and degree of interconnectivity of gelatins coatings on their tribo-mechanical behavior (P-h curves and scratch tests) were analyzed. Results revealed a new promising route to manufacture composite porous implants which are potential candidates to develop new treatments, not only for osteochondral defects, but also for other types of damages involving tissues of different nature (hard and soft) perfectly joined.
