“…Although Zr-5Ti exhibited the lowest R p values, surface modification by thermal oxidation in air was found to greatly improve the electrochemical characteristics of this material as well. The observed increase in the corrosion resistance has also shown to occur in these alloys when treated at 500 • C using similar procedures [20,21,31]. Scanning electron microscopy (SEM) images of the cross section of the three materials subjected to similar thermal treatment have evidenced the formation of oxide layers on top of the metallic material, resulting in a more compact oxide coating that exhibited higher resistance against corrosion for the Zr-45Ti material [31].…”

“…Although some binary Ti-Zr alloys -with Ti as the main component-have been adopted in the last decade for dental clinical applications [12,13], the same has not happened with binary Zr-Ti alloys, where Zr is the main component. Nonetheless, several studies correlated composition and structure with mechanical properties [14][15][16], and other works reported interesting corrosion resistance properties [17][18][19][20][21][22]. To date, the optimal ratio between Ti and Zr is still under investigation in order to combine mechanical properties similar to the host tissue where it will be implanted, a greater resistance against corrosion in the physiological environment, and good biological activity [23].…”

Binary Zr-Ti alloys spontaneously develop a tenacious and compact oxide layer when their fresh surface is exposed either to air or to aqueous environments. Electrochemical impedance spectroscopy (EIS) analysis of Zr-45Ti, Zr-25Ti, and Zr-5Ti exposed to simulated physiological solutions at 37 °C evidences the formation of a non-sealing bilayer oxide film that accounts for the corrosion resistance of the materials. Unfortunately, these oxide layers may undergo breakdown and stable pitting corrosion regimes at anodic potentials within the range of those experienced in the human body under stress and surgical conditions. Improved corrosion resistance has been achieved by prior treatment of these alloys using thermal oxidation in air. EIS was employed to measure the corrosion resistance of the Zr-Ti alloys in simulated physiological solutions of a wide pH range (namely 3 ≤ pH ≤ 8) at 37 °C, and the best results were obtained for the alloys pre-treated at 500 °C. The formation of the passivating oxide layers in simulated physiological solution was monitored in situ using scanning electrochemical microscopy (SECM), finding a transition from an electrochemically active surface, characteristic of the bare metal, to the heterogeneous formation of oxide layers behaving as insulating surfaces towards electron transfer reactions.

“…Živa je vrlo pokretan metal u okolini, i poseduje veliki afinitet prema sumporu pri čemu se vezuje za sulfhidrilne grupe ćelijskih enzima inaktivirajući na taj način ćelijski metabolizam [27][28][29][30][31]. Zbog svih navedenih osobina, sve veća je upotreba drugih metalnih legura poput Ni-Ti [32], Ni-Cr, Co-Cr [33][34], legure na bazi titana [35][36][37].…”

THE ELECTROCHEMICAL BEHAVIOR OF COPPER AND COPPER ALLOYS AS BIOMATERIALS Different types of metals are used in the stomatology for dental applications. The oral environment is aggressive medium for metals and leads to corrosion. The metals undergo to chemical or electrochemical reactions in the oral environment which resulting in dissolution and formation of different chemical compounds. The present article reviews and discussed the electrochemical behavior of copper and copper alloys in synthetic saliva.

“…In the last decade, several studies have reported on the potential application of ZrTi alloys as implant biomaterials due to their improved mechanical characteristics related to the amalgam's composition and structure [1][2][3][4], whereas other studies described their high corrosion resistance conferred by the combined effect of TiO 2 and ZrO 2 that jointly form the protective passive layers [5][6][7][8][9][10][11][12][13][14][15][16][17]. In contrast, only very few studies have attempted to characterize their biological activity either in vitro [18,19] or in vivo [20].…”

In this work we studied the main surface characteristics together with the in vivo osseointegration of three Zr-Ti alloys with hydroxyapatite-zirconia-silver (HAP-ZrO 2 -Ag) coating layer. The main purpose was to provide a quantitative evaluation and interpretation from micro to nano scale of the processes involved in the osseointegration of the HAP-ZrO 2 -Ag coated Zr-Ti specimens in a pig model. The surface characteristics were studied by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). After the insertion of the implants into pig tibia, the osseointegration was investigated by means of biochemical analysis as well as bone histomorphometric and computed tomography measurements. The results of this in vivo study sustains that the capacity of the Zr-Ti specimens coated with HAP-ZrO 2 -Ag to promote osteogenesis is significant during the first month after implantation as compared with the control, being influenced by the interactions between bone tissue and HAP-ZrO 2 -Ag surfaces, but also by the chemical composition of the alloys.
