Influence of oxygen ion irradiation on the corrosion aspects of Ti-5%Ta-2%Nb alloy and oxide coated titanium

Effect of ion beam irradiation on the corrosion behavior of the melt-spun ribbon Ti60Ni40

“…The results of the present investigation also fall in line with the other reported investigations [15,16]. Hua et al reported that the surface modification using nitrogen ion implantation significantly improved the corrosion resistance of the NiTi shape memory alloy [15].…”

“…Hua et al reported that the surface modification using nitrogen ion implantation significantly improved the corrosion resistance of the NiTi shape memory alloy [15]. In another investigation Ningshen et al [16] studied the influence of oxygen ion irradiation on the corrosion aspects of Ti-5% Ta-2%Nb alloy and oxide coated titanium. It was reported that the passive current density decreases with increase in ion doses which indicates decrease in anodic dissolution.…”

“…In our group several investigations were carried out on the corrosion behavior of several amorphous alloys Ti 60 Ni 40 , Ti 50 Cu 50, Ti 48 Cu 52 , Zr 67 Ni 33 , Zr 46.75 Ti 8.25 Cu 7.5 Ni 10 Be 27.5 and Zr 65 Cu 17.5 Ni 10 Al 7.5 and it was reported that Ti 60 Ni 40 exhibits superior corrosion resistance as compared to other amorphous alloys [8,9]. In contrast to a large number of investigations carried out on corrosion behavior of amorphous alloys, [4][5][6][7][8][9][10][11][12][13] only few investigations are available on corrosion behavior of the amorphous alloys after surface modification by ion beam irradiation [14][15][16]. This motivated us to carry out the present investigation on the effect of ion beam irradiation on the corrosion behavior of amorphous Ti 60 Ni 40 in 1 M HNO 3 aqueous medium.…”

Correlation of the nanostructure of the anodic layers fabricated on Ti13Nb13Zr with the electrochemical impedance response

“…In this sense, the b-titanium alloys, such as Ti-xZr, Ti-xNb-yZr-zTa, Ti-xNb-yTa and Ti-xNb-yZr, have been evaluated from corrosion viewpoint in different solutions. The results pointed out that these titanium alloys may show higher corrosion resistance than CP titanium and Ti6Al4V alloy due to the growth of a more compact and stable native passive film composed of a mixture of protective oxides (TiO 2 , Nb 2 O 5 , ZrO 2 and Ta 2 O 5 ) [15][16][17][18][19][20][21] The aim of this study is to analyze the corrosion behavior of anodic films grown on Ti13Nb13Zr in a fluoride containing solution. The samples were fully characterized by scanning electron microscope (SEM), Rutherford backscattering spectroscopy (RBS), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) to elucidate their electrochemical behavior in a phosphate buffered saline solution (PBS).…”

Structure of the oxide film on Ti–6Ta alloy after immersion test in 8mol/L boiling nitric acid medium

“…Comparing with the titanium, the improved corrosion resistance of the Ti-5Ta and Ti-5Ta-1.8Nb alloy for nuclear application could be attributed to the structure variation of the oxide film [7,8]. It is reported that the oxide film on Ti-5Ta-1.8Nb alloy contains not only the titanium oxide (TiO 2 ) but also the oxide of these refractory metals (Ta 2 O 5 and Nb 2 O 5 ) [9,10].…”
