Processing and Properties of BioCeramic Coatings onto 3D Ti-Mesh by DipCasting Method

This study presents a dipcasting method that can deposit both porous and dense bioceramic coatings onto 3D Ti-mesh made from commercially pure Ti-mesh for surgical applications. First, a dense bioglass coating was deposited onto the 3D Ti-mesh, which is to seal off the Ti-mesh. Second, a microporous HA/bioglass coating was deposited on top of the dense bioglass coating, which is to promote bone regeneration into the 3D Ti-mesh. X-ray diffraction, field emission scanning electron microscopy, and energy dispersive X-ray spectroscopy were used to analyze the bioceramic coatings and cross-sectional microstructures. Vickers microhardness across the interface between bioceramic coating and Ti-substrate was measured.
