The Influence of Strontium Oxide on the Physio-Mechanical Properties of Biomedical-Grade Titanium in Ti-SrO Composites

Abstract

Dental implants can be made of various materials, and amongst them, titanium and titanium alloy were the materials of choice for dental implants for many years because of their biocompatibility. The two alloys have a high level of biocompatibility, a lower modulus of elasticity, and better corrosion resistance than other alloys. Thus, they are frequently utilized in biomedical applications and mostly replace stiff fabrics. The latest advances in a new strontium oxide–cp titanium composite alloy are the main topic of this research. With regard to biomedical applications, additions of strontium oxide were synthesized at three distinct weight percentages (2%, 4%, and 6% by wt%). Powder metallurgy was used to create the alloys, which were then sintered by heating the samples. The effects of adding strontium oxide were analyzed by utilizing measurements of the Brinell hardness, X-ray diffraction, porosity, diametral tensile strength, roughness, and wettability of the finished surfaces. The results show that adding more strontium oxide (gradually increasing the ratio from 2% SrO to a 6% addition) raised the roughness and porosity. However, the microhardness and diametral tensile strength were enhanced with an increase in the volume fraction of strontium oxide particles. In conclusion, the alloy that contained 6 wt% strontium oxide microparticles had reasonably high mechanical properties and might be regarded as suitable for use in dental and medical applications due to its high wettability or, in other words, its low contact angle. The Brinell testing results for the diametral tensile strength, microhardness, and porosity of the generated strontium oxide–cp titanium composite alloy demonstrate its high potential for usage as a biomaterial, particularly in dental applications.

Metaheuristic Optimization of Functionally Graded 2D and 3D Discrete Structures Using the Red Fox Algorithm

“…Considering the structures that will be studied, one has to consider the first-order shear deformation to model their kinematical modelling [17][18][19][20][21]. The displacement field corresponding to this theory can be written as follows:…”

“…However, depending on the applications' characteristics, other material mixtures have been utilized as illustrated in the studies developed by [13][14][15][16][17], where mixtures of different metallic, polymeric, and ceramic materials were used. The FGM concept extended to materials with specific biocompatible characterisics can also be found with an increasing frequency, namely in [18][19][20], among others.…”
