In order to study the effect of microarc oxidation modification treatment on the friction properties of titanium alloy surface, the surface treatment layer of Ti-6Al-4V ELI specimen modified by Microarc oxidation surface was sampled, the surface layer hardness, roughness and treatment layer thickness were tested, the microscopic morphology was analyzed, The friction tests of TC4 substrate and micro-arc oxidation treatment surface disc with 25% glass fiber, 15% fiberglass +5% graphite and 60% tin bronze reinforced PTFE pin were carried out, and the results showed that the thickness increased slightly and the surface layer hardness increased by about 75% after the micro-arc oxidation surface modification treatment. Compared with the substrate, the surface roughness is obviously improved, and the friction coefficient of the surface treatment specimen is similar to that of the TC4 titanium alloy substrate, but the wear amount is higher than that of the TC4 titanium alloy substrate.

Welding Strength

Laser surface treatment of the titanium alloy was locally oxidized on the metal surface to improve the joint strength of laser transmission welding of high borosilicate glass with titanium alloy. The results find that the welding strength was increased 5 times. The welding mechanism was investigated by the morphology of the welded parts, the tensile-fracture failure mode, the diffusion of the interface elements, and the surface free energy. The results show that there are many adherents between the titanium alloy and high borosilicate glass after tensile fracture, the welding strength was higher when the laser voltage was 460 V, and the tensile–fracture failure mode is mainly ductile fracture. Element-line scanning analysis revealed that elemental diffusion occurred in the two materials, which is an important reason for the high welding strength. Surface free-energy analysis shows that laser surface treatment improves the surface free energy of titanium alloy, promotes the wettability and compatibility, and increases the welding strength of titanium alloy with glass.

Excellent Corrosion Resistance

Titanium alloys possess unique combination of good mechanical properties and excellent corrosion resistance which make them an attractive material for application in many engineering areas. Along with these properties there are some disadvantages which can be eliminated successfully using different surface treatment methods. One of the most commonly used among them is anodizing. This article presents investigation of the results obtained from anodizing titanium alloy Ti-6Al-7Nb using sulphuric acid. The quality assessment and morphology of the anodized layer is made using a micro structural analysis, EDS analysis, XRD analysis and microhardness measurements.

Biological Performance

We have developed a new Ti alloy, Ti-15%Zr-4%Nb-4%Ta alloy (Ti-15-4-4) that showed higher biological safety and mechanical properties than the currently used Ti-6%Al-4%V alloy. The purpose of this study is to determine the biological performance of the new alloy. Ti-15-4-4 implants (machined or blasted) were placed in surgically created defects in rabbit femurs. The rabbits were sacrificed after 4, 8, 16, 24 and 48 weeks. Bone mineral density (BMD) and area of newly formed bone around the implants were measured using micro-CT. Results showed that the Ti-15-4-4 alloy is biocompatible and forms new bone around the Ti-15-4-4 implant, regardless of the surface treatment. The BMD and area of newly formed bone around the blasted implant surfaces were significantly greater than those around the machined surfaces. These results indicate that the new Ti-15-4-4 alloy has a potential for use as implants and has the advantage of improved mechanical properties described in earlier studies.

Micro Arc Oxidation

Titanium oxide coatings （Ti/TiO2）were formed on the titanium net surface by micro-arc oxidation(MAO) in Na3PO4 solution using an AC power supply. Then the titanium oxide coatings were treated by acetic acid or La(NO3)3 aqueous solution to improve its activity. The structures and photocatalytic ability of titanium oxide coatings before and after surface treatment were characterized and evaluated by XRD, SEM, EDX. It was found that the titanium oxide film is mainly made of titanium and anatase .When acetic acid aqueous concentration is 0.1mol•L-1 and soak time is 6 hour ,the Ti/TiO2 films photocatalytic degradation rate increased from 15% to 33.6%. When La(NO3)3 aqueous concentration is 0.1mol•L-1 and soak time is 12 hour, the Ti/TiO2 films photocatalytic degradation rate increased from 15% to 34.8%.
