Abstract
The use of Ti6Al4V as a biomaterial has been limited due to the dissociation of V and Al ions into the surrounding environment which can cause inflammations, cell damage and toxicity. To prohibit these undesirable challenges, the addition of ZrO2 into Ti6Al4V was proposed because ZrO2 is biocompatible, it has good wear and corrosion resistant properties, it has low affinity to bacterial colonization and it has high fracture toughness. The aim of this work is to determine the optimum powder synthesising parameters by Tubular mixer and ball mill for fabrication of sintered composites. Powder mixtures were prepared by 49 rpm, 72 rpm and 74rpm for 2, 4 and 8 hours followed by spark plasma sintering at 1100°C at heating rate of 100°C/min for 10 min and pressure of 50 MPa. from the results obtained it was discovered that Tubular mixing of 90 Vol% Ti6Al4V and 10 Vol% ZrO2 at 72 rpm and ball milling of 90 Vol% Ti6Al4V and 10 Vol% ZrO2 at 74rpm speed have proved to produce homogeneous admixed powders, which can further produce fully dense SPS compacts with higher microhardness values.
Highlights
Ti6Al4V is a grade of titanium alloy which is considered suitable for the fabrication of implants
This alloy was developed to improve the properties of commercially pure titanium such as low strength and wear resistance for hard tissue replacements [1].Ti6Al4V properties range from good biocompatibility, good mechanical properties to good corrosion and wear resistance as such, it was considered a superior metallic biomaterial compared to cobalt-alloys and stainless [2]
An interesting trend discovered in these scanning electron microscope (SEM) results was the powders became more homogenous with an increase in speed and time from 49-72rpm and 2-8 hours
Summary
Ti6Al4V is a grade of titanium alloy which is considered suitable for the fabrication of implants. This alloy was developed to improve the properties of commercially pure titanium such as low strength and wear resistance for hard tissue replacements [1].Ti6Al4V properties range from good biocompatibility, good mechanical properties to good corrosion and wear resistance as such, it was considered a superior metallic biomaterial compared to cobalt-alloys and stainless [2] It was discovered by Manivasagam [3] that under a biological environment such as the human body it releases toxic metal ions of vanadium and aluminium leading to diseases such as Alzheimer.
