During metal additive manufacturing, porosity is one of the main quality defects products. Laser post-processing an effective method reducing surface and sub-surface. Herein, evolution mechanism multi pores during this process studied. Two samples for each alloy, Ti6Al4V AlSi10Mg, were fabricated by laser powder bed fusion (LPBF), upper sample alloy was scanned using a beam comparison. Then, in...

In this study, we fabricated poly(3-hydroxybutyrate-3-hydroxyvalerate) (PHBV) coatings doped with Gd3+ (1, 5, and 10 × 10−4 mol/L) on Ti6Al4V alloy for the first time to promote soft tissue sealing around dental implants. The corrosion resistance of Gd3+-modified PHBV-coated was studied by electrochemical immersion tests, respectively, whereas CCK-8 RT-PCR evaluated biocompatibility human gingi...

Although laser-assisted turning (LAT) has been studied for decades, little is known on the effect of bulk temperature rise and residual in workpiece. Here we report an investigation a comparison characteristics LAT Ti6Al4V alloy laser heating Al/SiC metal matrix composite (MMC) as two materials have significant differences thermal conductivities. The research shows that at low cutting speed wit...

The addition of tungsten can improve the high-temperature oxidation resistance titanium alloys. However, as its applications continue to expand, new demands are being placed on room temperature strength. Here, we provide a dense alloy with high strength by introducing proper W powders into Ti6Al4V under direct energy deposition. effect microstructure and tensile properties was investigated. Com...

The paper presents the possibilities of using wavelet transform to filter cutting force signal. Tests were carried out by dry turning on Ti6Al4V alloy with variable parameters. Four blades different nose geometry and coatings used. From recorded waveforms, mean values component Fc load stability coefficient calculated. measured waveforms filtered Daubechies 4 (db4) 6 (db6) wavelets. ratio stabi...

Wear of elements subjected to friction and sliding is among the main causes of low tribological performance and short lifetime of strategic materials such as titanium alloys. These types of alloys are widely used in different areas such as aerospace and the biomechanics industry. In this sense, surface modification treatments allow for the overcoming of limitations and improvement of features a...

Introduction Titanium and its alloys have excellent mechanical properties and biocompatibility. In the field of dentistry, smooth surfaced titanium implants inserted into the facial bones perform very well. After implantation, well-fixed dental implants, which are not subjected to weight loading during some period after implantation, exhibit direct contact with bone without intervening fibrous ...

The influences of Li content on the corrosion behavior TC4 (Ti6Al4V) titanium alloy were explored when was immersed in Al–Li melt containing 0%, 1%, and 2% lithium at 680 °C, 700 720 °C for 0.5 h, 1 2 h. structure growth law diffusion reaction layer solid–liquid interface studied, kinetic equation established. In addition, Ti determined its dissolution rate calculated. results showed that with ...
