It has been found that there is no straightforward relationship between the wear rate and the microstructure. The hardness has no appreciable effect on the wear behaviour of these alloys. The presence of boron in the TNZT alloy deteriorates its wear properties. The wear rate of TNZT and TNZTB alloys in various media increases in the following sequence: dry condition < Hank's solution < bovine serum. © 2010 Elsevier Ltd.enAlloysAnimalsBiomimetic MaterialsBoronCattleHardnessHot TemperatureMaterials TestingNiobiumSerumTantalumTitaniumZirconiumAlloysBody fluidsBoronBoron compoundsHardnessHeat treatmentMetal analysisNiobiumScanning electron microscopyTantalumTitaniumWear of materialsZirconiumalloyborontitaniumBovine serumDry conditionHank's solutionSimulated body fluidsSliding wear behaviourWearWear propertiesWear ratesarticlebody fluiddeteriorationhardnessheat treatmentpriority journalsimulationTitanium alloysArticle
