GR5 Titanium Alloy Disc

The GR5 and TA7 titanium alloys used in aviation were selected, and the test pieces were made into discs with a size of 40*5mm, and the surfaces of all test pieces were polished to a mirror surface.

1.2 Ion implantation conditions

Both titanium alloys use two implantation schemes:

① Ti is sputtered on the GR5 and TA7 titanium alloy specimens, and the total thickness of the Ti film is 540nm (5400A). is 50keV, the beam density is 45μA/cm2, the dose is 7*1017/cm2, and the vacuum degree of the target chamber is 1.33*10-2Pa;

② On the basis of ①, inject C+ again, the beam energy is 40keV, and the dose is 3*1017/cm2.

Hardness measurement

The microhardness of the injected and uninjected specimens was measured with HXD-1000 digital microhardness tester, and the measured load was 4.9×10-2N. The measurement results are listed in Table 1.

Table 1 Microhardness measurement results

Material Surface condition Microhardness/MPa Hardness increase factor

Not injected 2690 0

GR5 injection (N+ +N+2) 6399 1.38

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

Not injected 3133 0

GR5 injection (N+ +N+2) 4276 0.36

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

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