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 ...

Abstract Titanium carbonitrides Ti(C,N) coatings were prepared by plasma electrolytic nitrocarburizing in an solution containing ammonium nitrate, glycerol and ethanol. The coating consists of outer compound layer inner diffusion with a total thickness about 100μm. compounds consist amorphous TiO 2 . corrosion current density the is almost order magnitude lower than that Ti6Al4V substrate 3.5% ...

Laser micro bending process of Ti6Al4V square bar are carried out using a 3D thermo-mechanical finite element analytical model (FEM). The transient temperature fields, displacement fields, stress fields and strain fields are obtained and analyzed. The results show that the bending angel during laser micro bending process is in good agreement with experimental measurements. The effects of proces...

This paper mainly reports the wetting state of liquid droplets on a Ti6Al4V micro-nanoscale hierarchical structured hydrophobic surface. In this work, the detailed action mechanism of the secondary nanostructure in the hierarchical structure on the wetting-state transition (from the Wenzel state to the Cassie state) was revealed and discussed. The variation of micro-morphology of the sample sur...

Greenhouse gases (GHG) emissions impose major threat to global warming potential (GWP). Unfortunately manufacturing sector is one of the major sources that contribute towards the rapid increase in greenhouse gases (GHG) emissions. In manufacturing sector electric power consumption is the major driver that influences CO2 emission. Titanium alloys are widely utilized in aerospace, automotive and ...

In this paper, the tool wear mechanisms for low-frequency vibration-assisted drilling (LF-VAD) of carbon fiber-reinforced polymer (CFRP)/Ti6Al4V stacks are investigated at various machining parameters. Based on kinematics analysis, effect vibration amplitude chip formation, uncut thickness, radian, and axial velocity examined. Subsequently, LF-VAD cutting temperature, wear, delamination, geomet...

The service life of artificial joints has gradually failed to meet the needs patients. Herein, synergistic lubrication and antioxidant efficacies graphene oxide (GO) fullerenol (Fol) as biological lubricant additives for were investigated. mechanisms containing GO Fol at friction interface then revealed. Tribological tests showed that average coefficients Al2O3–Ti6Al4V pairs Ti6Al4V–UHMWPE coul...

Copper nickel indium (CuNiIn) and Molybdenum disulphide (MoS2) duplex coating is used in aero engine compressor blades of Ti6Al4V to prevent fretting failure. Surface before roughened by grit blasting process for adhesion. In present study, place blasting, laser surface texturing (LST) preparation compared with blasted surface. Four different elliptical square patterns are created LST on Ti6Al4...
