Influence of Aluminum and Copper on Mechanical Properties of Biocompatible Ti-Mo Alloys: A Simulation-Based Investigation

Abstract

The use of titanium and titanium-based alloys in the human body due to their resistance to corrosion, implant ology and dentistry has led to significant progress in promoting new technologies. Regarding their excellent mechanical, physical and biological performance, new titanium alloys with non-toxic elements and long-term performance in the human body are described today. The main compositions of Ti-based alloys and properties comparable to existing classical alloys (C.P. TI, Ti-6Al-4V, Co-Cr-Mo, etc.) are used for medical applications. The addition of non-toxic elements such as Mo, Cu, Si, Zr and Mn also provides benefits, such as reducing the modulus of elasticity, increasing corrosion resistance and improving biocompatibility. In the present study, when choosing Ti-9Mo alloy, aluminum and copper (Cu) elements were added to it. These two alloys were chosen because one element is considered a favorable element for the body (copper) and the other element is harmful to the body (aluminum). By adding the copper alloy element to the Ti-9Mo alloy, the elastic modulus decreases to a minimum value of 97 GPa, and the aluminum alloy element increases the elastic modulus up to 118 GPa. Due to their similar properties, Ti-Mo-Cu alloys are found to be a good optional alloy to use.

Overview of Surface Modification Strategies for Improving the Properties of Metastable Austenitic Stainless Steels

“…In some cases, acid washing may, in addition to cleaning, improve corrosion resistance by removing parts of the surface. Electro-polishing, pickling, and passivation are the most important methods included in this classification [112][113][114][115]. In this regard, the electro-polishing process typically produces a surface that has an optimal corrosion resistance.…”

Mechanical Characterization and Microstructural Analysis of Stir-Cast Aluminum Matrix Composites (LM5/ZrO2)

“…To compare various materials and methods, tensile properties are measured when producing new materials and processes. Eventually, the tensile characteristics are used to assess a material's behavior under conditions apart from uniaxial stress charging [35,36]. The stress required for significant plastic deformation or the maximum stress a material can withstand can be used to gauge a material's strength, which is always the main issue.…”

Characterization and Optimization of Cu-Al2O3 Nanocomposites Synthesized via High Energy Planetary Milling: A Morphological and Structural Study

“…Copper-based nanocomposites have been studied extensively due to the high thermal and electrical conductivity of copper [1][2][3][4], as well as its low cost and availability [5,6]. The incorporation of ceramic nanoparticles, such as alumina, into the copper matrix can improve the mechanical properties [7,8], such as hardness and wear resistance, without compromising the electrical and thermal conductivity [9][10][11].…”
