In this study, Mg-Ca-Zn-Co alloy specimens for biomedical applications were produced by the powder metallurgy method. The Mg-Ca-Zn-Co alloy could be used as a scaffold material in tissue engineering applications. Electrochemical corrosion behavior of the specimens was investigated in simulated body fluid environment. Electrochemical corrosion resistance of the specimens was increased with increasing Zn and Ca contents of the alloy up to an optimum composition and then decreased. Optimum values for Ca and Zn additions were about 0.7 wt.% and 3.0 wt.% respectively. Young's modulus values of the specimens were determined by nondestructive ultrasonic measurement. Alloying element addition increased the Young's modulus of the specimens. Precipitation hardening of the Mg-Ca-Zn-Co alloy increased the Young's modulus and the corrosion rate of the specimens.

“…The porosity of the oxide film is increased by F 2 and low pH, due to the dissolution. [37][38][39][40][41] Effect of Cu content of the alloy Figure 12 shows the effect of Cu content of the Ti-Nb-Cu alloy on the Nyquist plots of the specimens in the artificial saliva. Figure 13 illustrates the effect of Cu content of the alloy on the Bode magnitude Z mod and the Bode phase angle plots of the specimens.…”

In the present study, highly porous Ti-Nb-Cu alloy foams were produced by a powder metallurgy method for biomedical implant (hard tissue) applications. Nb was added in order to stabilize the beta-Ti phase. Cu addition enhanced sinterability and reduced the sintering temperature of the alloy. Electrochemical corrosion behaviour of the Ti-Nb-Cu alloy specimens was examined by the electrochemical impedance spectroscopy method in an artificial saliva environment. Effects of porosity of the foam, Cu content of the alloy, pH and fluoride content of the artificial saliva solution on the electrochemical corrosion properties of the specimens were investigated. Mechanical properties of the specimens were also studied by compression tests.

“…The most widely used ones are bioactive glasses [11][12][13][14][15], calcium phosphate-based cement and ceramics, biodegradable polymer-based composites, and special alloys (Ti, Zr) etc. [16][17][18][19][20][21]. All the materials have numerous advantages but none of them fulfil the requirements completely.…”

Replacement of damaged or missing bone tissue is a serious problem in orthopedic surgery. Although various artificial materials are available, none of them fulfil the requirements completely. In this study, new bone substitute materials, silica aerogel-based β-tricalcium phosphate, and hydroxyapatite composite ceramics, along with a control sample were synthesized and tested. Porosities and pore size distribution curves were determined by nitrogen gas adsorption/desorption porosimetry, and surface morphology changes were studied by scanning electron microscopy. Bioactivities were tested in vitro by soaking the samples in simulated body fluids (SBF). Three new advanced SBFs containing eight essential amino acids and bovine serum albumin were developed, extending the complexity of the original simulated body fluid in order to approximate the human blood plasma's composition more accurately. Each sample was treated with SBF1-SBF4 for two weeks. According to our results, it seems to be necessary to re-evaluate hydroxyapatite deposition as proof of bioactivity of artificial bone substitutes when synthetic body fluids analogous in their composition to human blood plasma are used in studies.
