Practical application effect is tested, and work the case where will be not added with and only add multi-layer graphene or di-iron trioxide nano particle
For comparison.
Test specification determination is as follows:
Pin sample is 5 × 23 mm of Φ2TC11 alloy；Disk sample is 34 × 10 mm of Φ2GCr15 bearing steel, hardness 50
HRC；Sliding speed is 0.5 m/s；Revolution is 10000 turns (about 1600 m)；Load is 20-120 N, is divided into 20 N.Test

The nanocomposite of 1-4 is added to TC11 alloy/GCr15 steel sliding interface.
Experimental result and analysis conclusion:
Test result is as shown in Figs. 1-3.
Only when addition multi-layer graphene, TC11 alloy wear rate ratio is also high when being not added with, and coefficient of friction variation is little.
Only when addition di-iron trioxide nano particle, wear rate is very low under low load, and height increases under carrying, and average friction coefficient
It is apparently higher than when being not added with.
When adding the nanocomposite of 1-4 of the embodiment of the present invention, the wear rate of alloy still keeps extremely low in the case where height carries
Value, average friction coefficient are also declined.
Particularly, when adding embodiment 3, until 120 N, wear rate and coefficient of friction remain extremely low.
To find out its cause, titanium alloy surface will form frictional layer when adding nano material, composition depends on nano material
Component.
Only addition multi-layer graphene, frictional layer do not have bearing capacity, destroy under low load.
Only addition di-iron trioxide nano particle, though frictional layer has certain bearing capacity, its lubricity is poor, performance
Higher for coefficient of friction, height easily destroys under carrying because of shear stress.
The gradient frictional layer high stability that is formed when only adding nanocomposite of the present invention, simultaneously containing it is wear-resistant with
Antifriction component, two layers of frictional layer mutually cooperate with, and the friction and wear behavior of TC11 alloy is caused to be significantly improved.
Particularly, double-deck when the nanocomposite or oxide particle size that add oxide-rich are small, surface area is big
Contain more multiple-bearer component in frictional layer, it is promoted still to be stabilized under more top load, titanium alloy has more excellent rub
Wipe polishing machine.However, abrasion resistant component is also not The more the better, such as embodiment 4, antifriction constituent content is lower at this time, is rubbing
In wear process, frictional layer, which lacks enough lubricating abilities, more steadily to be existed, thus it is wear-resistant in nanocomposite, subtract
Component of rubbing has a preferably ratio range, and embodiment 3 is optimum embodiment.
Compared with Chinese patent CN201611018013.7, effect of the invention has following progress:
Titanium alloy can carry the even higher load of 120 N(in height) under, there is extremely low wear rate and coefficient of friction, main cause
It is under equal conditions, the composite material of addition promotes the abrasion resistant component di-iron trioxide in frictional layer containing higher amount, promotes
Frictional layer has extremely strong stability, and then the antiwear and antifriction function of playing stably.
