“…This lead to the conclusions that while fluoride concentration increases corrosion resistance of Ti and its Ti6-A1-4V alloy decreases [12]. Ti-Co alloy [10] and Ti-Cu alloy [24] gave parallel consequences. Unpredictably, the presence of Ta in the Ta30Ta alloy has a valuable achieve on its behavior in acidified fluoridated AS [11].…”

“…To recognize these effects, numerous investigations were undertaken. Corrosion resistance of metals and alloys in AS, in the presence of fluoride has been investigated [1,10,11,12,14,19,24] The presence of fluoride ions (added as NaF) drastically affects the corrosion behavior of Ti metal, Ti-6Al-7Nb, and Ti-6Al-4V alloys and constituent metals in AS as confirmed by electrochemical methods [1]. All the titanium alloys in fluoridated acidified saliva show an active behavior due to the presence of major concentrations of HF and HF2− species that dissolve the spontaneous air-formed oxide film giving rise to surface activation [13].…”

“…It is further enhanced by the fluoride ions in toothpaste and in the products used as mouthwash as it plays the role of an essential factor accelerating corrosion [5][6][7][8][9]. Corrosion resistance of biomaterials made up of various metals and alloys has been investigated in artificial saliva (AS); various metals and alloys such as Ti-Co alloy [10], Ti30Ta alloy [11], Ti metal, Ti6-Al-7Nb, and Ti-6Al-4V alloy [1,12], Ti-6Al-7Nb alloy [13], Co-Cr alloy [14][15][16][17][18], CP-Ti and Ni-Cr-Ti alloy [19], Co-Cr-Mo alloy [20,21], Ni-Cr alloy [18,22,23], Ti-Cu [24], Ti-20Zr alloy [25], Ti12Mo and Ti60Ta [26], Ni-Ti shape memory alloy and stainless steel wire [27], Ti-Mo [28], mild steel coated with zinc [29], NaOCl [30], and 60NiTi [31]. Corrosion resistance of various metals has been investigated in AS.The composition of artificial saliva is given in Table 1.…”

Dental erosion is the chemical dissolution of the tooth structure. Factors like eating disorders and gastrointestinal diseases are recognized as intrinsic factors for dental erosion. To regulate the growth of teeth, people are implanted with orthodontic wires made of different materials. These are exposed to the influence of oral environment, food intake, toothpastes, and mouthwashes. During this process, the materials may undergo corrosion. Hence, various researchers have made a study on the influence of artificial saliva (AS) on the corrosion behavior of these alloys. The excellent corrosion resistance to the oral environment of dental alloys is important for biocompatibility as well as for orthodontic employment permanence. Various types of metal alloys are being used for the orthodontic treatment, which undergo chemical or electrochemical reaction with the oral environment. The oral environment is highly belligerent under several situations and leads to corrosion. This article reviews the effects of fluoride concentration, the pH value and protein content in AS and the composition of the metal alloys on the corrosion resistance of orthodontic appliances using electrochemical methods and surface characterization techniques such as scanning electron microscopy inductively coupled plasma-optical emission spectroscopy (ICP-OES) and X-ray photoelectron microscopy.

“…Recently, alloys of Ti-Co were designed for dental applications because of the lower melting point in comparison to the Ti6Al4V and the CoCrMo, as well as the higher values of hardness and good stability of such alloys [29][30] . Based on the Ti-Co binary phase diagram, eutectic reactions may occur above 1020°C, depending of the weigh percent of Co 31 .…”

A composite of Ti6Al4V reinforced with CoCrMo particles is fabricated by conventional powder metallurgy and semi-solid sintering. Composites are fabricated by mixing 20% wt. of CoCrMo reinforcing particles into the Ti6Al4V matrix. Sintering is studied by dilatometry tests between 1050 and 1130 °C and compact characterization is performed by SEM and XRD. Microhardness is evaluated on the polished surface in order to obtain the mechanical properties. It is found that densification is achieved by the formation of a liquid phase due to a eutectic point formed by the Ti and Co at around 1130 °C. Composites with 93% of relative density are obtained. Their microstructure is composed by the Ti6Al4V matrix surrounded by a Ti 2 Co phase. Average microhardness of composites is higher than that obtained for monolithic samples of both alloys. It is assessed that the control of the liquid phase is the key to obtain highly dense composites that could be used as dental or orthopedic implants.
