“…As such, multiple studies have examined β-type Ti alloys to overcome the limitations of Ti-6Al-4V The Ti-6Al-4V alloy, which was developed in the United States, was used for the first time in the medical industry in 1954 [2]. As Ti-6Al-4V possesses superior mechanical properties, is biocompatible, and does not interfere with innovative imaging methods such as computer tomography and magnetic resonance imaging, it remained the primary Ti alloy used in orthopedics and dentistry for a very long time [115,[120][121][122][123][124][125][126][127][128][129][130]. However, multiple studies have raised the issue of the toxicity of the Al and V found in the Ti-6Al-4V alloy.…”

Metal injection molding (MIM) is one of the most widely used manufacturing processes worldwide as it is a cost-effective way of producing a variety of dental and orthopedic implants, surgical instruments, and other important biomedical products. Titanium (Ti) and Ti alloys are popular modern metallic materials that have revamped the biomedical sector as they have superior biocompatibility, excellent corrosion resistance, and high static and fatigue strength. This paper systematically reviews the MIM process parameters that extant studies have used to produce Ti and Ti alloy components between 2013 and 2022 for the medical industry. Moreover, the effect of sintering temperature on the mechanical properties of the MIM-processed sintered components has been reviewed and discussed. It is concluded that by appropriately selecting and implementing the processing parameters at different stages of the MIM process, defect-free Ti and Ti alloy-based biomedical components can be produced. Therefore, this present study could greatly benefit future studies that examine using MIM to develop products for biomedical applications.

Different industries, including aerospace, marine, and automotive, widely use titanium alloys such as Ti-6Al-4V. Although, this alloy has excellent properties; it is highly susceptible to corrosion and has low thermal stability and tribological characteristics, limiting its application. In this research, after preparing the Al62.5Cu25Fe12.5 quasi-crystalline (QC) powder mixture and appropriate target, the magnetron sputtering method was employed to deposit the QC coating on the Ti-6Al-4V substrate. The powder mixture and AlCuFe thin films were annealed at 700 0 C for 2 h. The scanning electron microscope (SEM) analysis and X-ray diffraction (XRD) methods were used to investigate the microstructure and morphology of mixed powders and Al-Cu-Fe QC coatings. NaCl solution (3.5 wt.%) was utilized to conduct the electrochemical measurements. Al-Cu-Fe thin layer deposited on the Ti-6Al-4V alloy surface without any cracks. The XRD patterns related to the annealed powders and the coating after heat treatment indicated the presence of Cu3Al, AlFe3, and quasi-crystalline ternary phases of Al65Cu20Fe15, Al3Fe, AlTi2, and Al65Cu20Fe15 phases, respectively. Based on the polarization test results, the annealed coating at 700°C showed better electrochemical behavior than the Ti-6Al-4V substrate.

“…Various corrosion tests have already been carried out on implant materials and titanium alloys in the literature, using methods such as open circuit potential (OCP), potentiodynamic and potentiostatic tests, and electrochemical impedance spectroscopy (EIS) [38][39][40]. Again, in these studies, corrosion behavior was investigated by using 0.9 wt wt% NaCl, Kroll or Hank solutions [41][42][43][44]. However, there are currently no studies carried out by creating a naturally corrosive environment after fiber laser welding of Ti-6Al-4V (Gr5) alloys in rod form.…”

The corrosion resistance of laser welded samples was carried out in a shaken incubator in body-simulated liquid environments and kept at pH3-5 and 25-50˚C conditions for 24 hours. It was determined that acicular α' martensite structures were formed in the fusion regions and these structures increased the hardness of the alloy by 20% compared to the base metal. The welded samples had the highest tensile strength of 144 MPa. Weight changes after the corrosion test were calculated and the highest weight loss was found to be 0.0025 g for the sample with an initial weight of 4.1394 g. TiO2 oxides and {1 0 0} and {1 1 1} chamber-shaped salt crystals were formed larger and more intensely in the fusion zones than the base metal. Dental metallic implant welding with fiber laser will have higher corrosion resistance in oral use with different temperature and pH environments compared to screw joints.
