How- ever, one of the drawback of such implants is high cost due to the technological di°culties in casting method or machining. In this work, powder injection moulding (PIM) method has been used in order to explore lower cost implants without min- imising the biocorrosion resistance of the titanium. Corrosion resistance of titanium specimens, produced by powder injection moulding method (PIM-Ti), in physiologic serum and artificial saliva was investigated. Commercially pure bulk Ti (CP-Ti) was used as control sample. Surface oxidation was also carried out to both PIM- Ti and CP-Ti samples. Microstructure and corrosion resistance were investigated using microhardness, X-ray diffraction (XRD), scanning electron microscopy (SEM) and potentiodynamic polarization experiments. Resulting microstructure of PIM-Ti samples contained porosity as compared to CP-Ti control samples. Microhardness of PIM-Ti samples varied with varying applied load whereas it was free from applied load for CP-Ti control samples. Polarisation measurements and SEM analysis re- vealed that corrosion behaviour of PIM-Ti was reasonably as good as CP-Ti both in as-produced and oxidized conditions in physiologic serum and artificial saliva in spite of its porous structure.eninfo:eu-repo/semantics/closedAccessCorrosionOxidationPowder injection mouldingTitaniumArticle2-s2.0-786500368142053Q119723
