“…Radiologically, there was no evidence of any osteolysis around implants in either group, which contrasts with the findings of Venable et 01 [3] who found evidence of osteolysis and necrosis around stainless steel implants which was attributed to electrolysis of implant material.…”

“…The objectives of these studies have been (1) to compare the kinetics of hydroxyapatite crystallization on the substrates with the solution kinetics reported by Eanes, Gillensen, and Posner [ 19,201 , (2) to evaluate the morphology of the surface crystallized hydroxyapatite, and (3) to evaluate the strength of the hydroxyapatite to glass-ceramic bond.…”

“…Today, the most widely used implants in orthopedics are made from metals because of their relative tissue inertness and strength characteristics. In 1937, Venable, Stuck, and Beach published a paper on "The Effects on Bone of the Presence of Metals; Based Upon Electrolysis [2] ." In this paper they concluded that dissimilar metals will produce an electrolytic reaction within the tissues and that the alloy of least reaction was one called Vitallium.…”

“…Uma das aplicações mais frequentes refere-se ao uso de implantes na restauração de estruturas ósseas e articulações nas próteses totais de quadril [1]. Entre os materiais metálicos convencionais para tal emprego podem ser citados o aço inoxidável ASTM F138, a liga à base de Co-Cr-Mo, e a liga Ti-6Al-4V [2][3][4][5][6][7][8][9][10], sendo este última a mais apropriada para implantes femorais devido à sua alta resistência mecânica, menor módulo de elasticidade e excelente resistência à corrosão [6,7,9,10]. No entanto, nos últimos anos a literatura vem registrando diversos estudos sobre a toxidade dos elementos de liga e a reabsorção óssea como fatores que causam a falha de implantes [7,[9][10][11][12][13][14][15].…”

ResumoNeste trabalho, o comportamento eletroquímico das ligas Ti-35Nb-xTa (x = 0; 2,5; 5,0; 7,5)Ta (% em peso), solubilizadas e resfriadas em água, foi investigado em meio de NaCl a 0,9% mol/L através de testes de polarização anódica e medidas de impedância, micrografias e DRX. Os ensaios eletroquímicos mostraram que as ligas contendo tântalo apresentam uma maior resistência à corrosão que a liga sem tântalo. Além disso, os ensaios eletroquímicos em conjunto com as micrografias e DRX indicam que a composição Ti-35Nb-5Ta é a que apresenta maior resistência à corrosão no meio estudado, pois além de ocorrer uma estabilização da fase , o refino do grão foi menos pronunciado e por esse motivo minimizou o surgimento de microcélulas eletroquímicas.

CORROSION RESISTANCE OF Ti-35Nb-xTa ALLOYS IN 0.9% NaCl SOLUTION AbstractThis work is a study of the electrochemical behavior of the Ti-35Nb-xTa alloys (x = 0, 2.5, 5, 7.5) (wt. %), solution treated and quenched in water. Anodic polarization tests and impedance measurements were carried out in these compositions by using a solution of 0.9% NaCl; their microstructures and XRD patterns were also obtained. The results showed that the alloys containing tantalum have a higher corrosion resistance than that one without Ta. In addition, electrochemical tests, together with the micrographs and XRD, indicate that the Ti-35Nb-5Ta composition is the most resistant to corrosion in the medium analyzed. This fact is a consequence of the stabilization of the  phase, and of its grain size, where the refinement effect of Ta is not enough strong and minimizes the formation of electrochemical microcells.
