“…Such peaks are visible in the FTIR spectra for both HA and HA/ZrO 2 coatings (Fig. 4B) and can be attributed to the presence of other calcium phosphate phases, such as tetracalcium phosphate (Ca 4 (PO 4 ) 2 O, TTCP), TCP (Ca 3 (PO 4 ) 2 ) and/or oxyhydroxyapatite (OHA) [34,35]. The structural decomposition of deposited coatings was also revealed by XRD studies (Fig.…”

“…The combination of calcium phosphate ceramics and metallic reinforcements has been considered as a promising alternative to achieve both bioactivity and mechanical strength in one material. The most commonly explored combination is the composite containing hydroxyapatite matrix toughened with titanium particles [3][4][5]; however, it has been found that the presence of titanium promotes the partial decomposition of hydroxyapatite during sintering [4]. Therefore, in the present work, we investigated a metal-ceramic composite based on iron and tricalcium phosphate, which could be a good alternative to hydroxyapatite-titanium composites.…”

“…Among the different alternatives, titanium and hydroxyapatite are two of the most extensively used materials to treat bone fractures [1,2], so the interactions between them during sintering has been studied in detail [3,4]. The results show that the fabrication of titanium-hydroxyapatite composites is technically feasible.…”

“…The results show that the fabrication of titanium-hydroxyapatite composites is technically feasible. However, the disadvantage of this system is that titanium catalyzes the thermal degradation of hydroxyapatite during sintering, generating mixtures of titanium, hydroxyapatite, calcium and titanium oxides and phosphates [4], which leads to detrimental mechanical properties [5]. In the present work, a different system is considered and studied as a potential candidate to overcome this decomposition drawback.…”

Chemical Stability of Tricalcium Phosphate–Iron Composite during Spark Plasma Sintering

Tricalcium phosphate (Ca 3 (PO 4 ) 2 , TCP) is a ceramic widely used as a bone filler material due to its good osteoconductivity. Nevertheless, its poor mechanical properties do not allow its use for load-bearing applications. Therefore, the option of improving its strength and toughness by adding a biocompatible metallic component is a promising alternative to overcome this drawback, leading to the fabrication of improved bone implants. The present work is focused on defining the thermal stability of alpha-TCP (α-TCP) when it is sintered together with iron (Fe) by spark plasma sintering. The results showed the thermal stability of the composite with no degradation or oxidation in the ceramic or metal phase. A clear advantage from the TCP-Fe composites when compared with others, such as hydroxyapatite-titanium, is the complete retention of the TCP due to the less reactivity with iron respect to titanium. Furthermore, the allotropic phase transformation from alpha to beta-TCP polymorph was reduced by sintering at 900 • C. However, the densification of the material was also impaired at this temperature. It is expected that spark plasma sintering will allow the fabrication of TCP-Fe composites free of secondary phases that compromise the mechanical strength of the material.

“…The oxygen level in sample B was lower than that in sample A, indicating that the oxidation level of sample B was lower than sample A. The presence of Ti in the compound influenced the oxidation level where titanium started oxidising at a low temperature of 450°С compared to HA which started to decompose at above the temperature of 850°С [40]. It is clear that the oxidation level of sample A was higher than sample B due to the high proportion of Ti in the sample.…”

Titanium alloys (Ti6Al4V) and hydroxyapatite (HA) are widely used as implant materials. Ti6Al4V has good mechanical properties and corrosion resistance, whereas HA has excellent biocompatibility but its mechanical properties are weak. The combination of properties between Ti6Al4V and HA is expected to produce a superior material for bio-implants. The aim of this work is to analyse the fabricating porous Ti6Al4V/HA composite through powder compaction with the application of two types of space holders. Sodium chloride (NaCl) and polymethyl methacrylate (PMMA) were selected as the space holder agents. Space holders were removed by solvent debinding (NaCl) and thermal debinding (PMMA). Sintering was performed in a furnace at 1200 °C for 1.5 h. The Archimedes method was carried out to obtain the porosity of the sintered body. Samples where NaCl was used exhibited higher porosity than the samples where for PMMA was used. The high porosity achieved among the successfully sintered samples was 43.9%. Interconnected porous was clearly observed on the sintered composites with a successfully generated size range of 2 μm to 25 μm.
