Product details
Product details

The composition of the titanium alloy TC4 material is Ti-6Al-4V, which belongs to (a + b) type titanium alloy and has good comprehensive mechanical and mechanical properties. Greater specific strength. The strength sb of TC4 = 1.012GPa, the density g = 4.4103, the specific strength sb / g = 23.5, and the specific strength sb / g of alloy steel is less than 18. Titanium alloy has low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum. The thermal conductivity of TC4 is l = 7.955W / m · K. Coefficient of linear expansion = 7.8910-6, Specific heat = 0.612cal / g ·. Titanium alloys have low elastic modulus. The elastic modulus E of TC4 is 110GPa, which is about 1/2 of that of steel, so it is easy to deform when processing titanium alloy. TC4 (Ti-6Al-4V) and TA7 (Ti-l-2.5Sn) titanium alloys are surface modified by two implantation schemes. Tests show that titanium alloys have improved microhardness and significantly reduced their ion implantation. The sliding friction coefficient was improved, and the abrasion resistance was effectively improved. In order to find out the modification mechanism, X-ray photoelectron spectroscopy (XPS) analysis was performed on the injected and uninjected samples, and satisfactory results were obtained.

Test specimen preparation and injection conditions

1.1 Test specimen preparation

TC4 and TA7 titanium alloys for aviation are selected, and the test pieces are made into a disc shape with a size of 405mm. All the surfaces of the test pieces are polished to a mirror surface.

1.2 Ion implantation conditions

Both titanium alloys use two injection schemes:

Ti was sputter-plated on TC4 and TA7 titanium alloy specimens, and the total thickness of the Ti film was 540 nm (5400 A). During the Ti coating process, (N + + N + 2) was used for dynamic recoil injection at the same time, and the beam energy was 50keV, beam density is 45μA / cm2, dose is 71017 / cm2, and target chamber vacuum is 1.3310-2Pa;

On the basis of C +, the beam energy is 40keV and the dose is 31017 / cm2.

Hardness measurement

The HXD-1000 digital micro hardness tester was used to measure the microhardness of the injected and uninjected specimens. The measured load was 4.9 × 10-2N. The measurement results are shown in Table 1.

Table 1 Microhardness measurement results

Surface hardness of material / MPa

Unfilled 2690 0

TC4 injection (N + + N + 2) 6399 1.38

Injection (N + + N + 2) + C + 3436 0.28

Unfilled 3133 0

TA7 injection (N + + N + 2) 4276 0.36

Injection (N + + N + 2) + C + 4073 0.30

It can be seen from Table 1 that the microhardness of the specimens has been improved to varying degrees after ion implantation. Among them, the hardness of the TC4 titanium alloy implanted with (N ++ N + 2) mixed beam is increased by about 1.4 times.

TC4 thermal expansion coefficient:

TC4 titanium alloy has a series of advantages such as excellent corrosion resistance, small density, high specific strength and good toughness and weldability. It has been successfully applied in aerospace, petrochemical, shipbuilding, automotive, pharmaceutical and other sectors. .

TC4 titanium alloy mechanical properties:

Tensile strength σb / MPa895, prescribed residual elongation stress σr0.2 / MPa825, elongation δ5 () 10, section shrinkage ψ () 25

TC4 titanium alloy density:

4.5 (g / cm3) working temperature-100550

Chemical composition of TC4 titanium alloy:

TC4 contains the balance of titanium (Ti), iron (Fe) 0.30, carbon (C) 0.10, nitrogen (N) 0.05, hydrogen (H) 0.015, oxygen (O) 0.20, aluminum (Al) 5.56.8, vanadium (V 3.54.5
