Description
Technical Field
The invention relates to the technical field of materials, in particular to an antiwear antifriction water dispersion emulsion for a titanium alloy surface and a use method thereof.
Background
The titanium alloy is widely applied to various fields of aerospace, navigation, automobiles, energy, chemical industry, biomedical use and the like. However, titanium alloys are not excellent in poor wear resistance and friction lubricity, limiting the field of application. Improving the frictional wear properties of titanium alloys has been a continuing effort by the skilled artisan.
The optimization of the sliding condition of the friction layer is a simple and practical wear-resistant antifriction technology. In recent years, some researchers at home and abroad have new knowledge when further exploring the dry sliding friction and wear performance of the titanium alloy, and under special conditions such as high temperature and high speed, an oxide-containing friction layer is formed on the surface of the titanium alloy, so that the titanium alloy has a protective effect, and the wear resistance of the titanium alloy is improved.
However, such protection is incomplete, e.g., such oxides must be formed under certain conditions, but hardly formed under conventional conditions; moreover, the formation of the friction layer is based on the consumption of the friction pair matrix material, which will cause abrasion of the material; more importantly, the antiwear properties of antiwear materials do not always reduce friction at the same time, resulting in insufficient lubrication.
Chinese patent CN 201611018013.7 is an antiwear antifriction material, which contains antiwear agent 33-83% and antifriction agent 17-67%. Wherein the antiwear agent is ferric oxide nano particles, and the antifriction agent is multilayer graphene. The two nano materials are mixed and stirred uniformly and then are directly added to the sliding interface of the titanium alloy component, so that the self-lubricating nano material containing the oxide can be formed. The method has the following defects: the antiwear material cannot be well distributed on the interface, and the multilayer graphene is used, so that the lubricating capability is insufficient, and the antifriction and antiwear functions cannot be continuously exerted.

Comparative example 3
The wear-resistant antifriction aqueous dispersion emulsion for the surface of the titanium alloy comprises cubic silicon carbide aqueous dispersion, polyvinyl alcohol aqueous solution and polytetrafluoroethylene aqueous emulsion, wherein the volume content of each component of the aqueous dispersion emulsion is 15 percent of the cubic silicon carbide dispersion, 2.5 percent of the polytetrafluoroethylene emulsion and the balance of water.
The prepared anti-wear antifriction water-dispersible emulsion on the surface of the titanium alloy in the above examples and comparative examples is prepared for use, and when in use, the preparation method comprises the following steps:
(1) Cleaning and degreasing the surface of the titanium alloy;
(2) Treating the titanium alloy by a silane coupling agent KH550, and drying for later use;
(3) Soaking the surface of the treated titanium alloy into the prepared emulsion;
(4) The immersed emulsion is dried and then used.
The soaking time is not less than 5min, and the drying temperature is 100-150 ℃ after the soaking is finished.
The testing process comprises the following steps: the actual application effect of the invention in TC11 alloy in dry sliding friction and wear is tested by adopting an MPX-2000 type disc pin type friction and wear testing machine. The test specifications were determined as follows: the pin sample is TC11 alloy with phi 5 multiplied by 23 mm 2; the disk sample is GCr15 bearing steel with phi 34 multiplied by 10mm < 2 >, and the hardness is 50 HRC; the sliding speed is 0.5 m/s; the sliding distance is 800-4000 m, and the interval is 800 m; the load was 100N. The coefficient of friction value is automatically read out by the software matched with the testing machine at intervals of 0.001 s.
Conclusion of experimental results analysis:
in comparative example 2, when only polyvinyl alcohol and polytetrafluoroethylene were added, the abrasion rate of the TC11 alloy was higher than that in the case of no addition, and the friction coefficient was kept low for a very short period of time and then increased to the level in the case of no addition.
In comparative example 1, the abrasion rate was slightly lower than that of comparative example 2 when only cubic silicon carbide and polyvinyl alcohol were added, and the friction coefficient was raised to be high within a sliding distance of about 150 m and then lowered to a level when not added, rather than adding any material.
When the nano-hybrid material is added, the wear rate and friction coefficient remain extremely low over a range of sliding distances, and then rise. In particular, the wear rate and coefficient of friction remained extremely low up to 4000 m according to the formulation of example 4, which was additionally tested and found not to gradually start to rise until 8800 m. For this reason, when the nanomaterial is added, the titanium alloy surface will form a friction layer whose composition depends on the composition of the nanomaterial. The friction layer has no bearing capacity only by adding polytetrafluoroethylene, and the friction layer is destroyed in a short time. The friction layer has a certain bearing capacity but poor lubricity, which is shown by a high friction coefficient in a period of time when sliding starts, by adding cubic silicon carbide, so that the friction layer is broken in a short time under a high load of 100N due to shearing stress.
Comparative example 3 shows that both antifriction and antiwear components are added, but no polyvinyl alcohol is added, the gap between the two materials is free of fillers and fixtures, and the sustainability is insufficient, resulting in poor frictional wear properties of the alloy, and the wear rate gradually increases from 2000m over example 4.
When polyvinyl alcohol is added, the friction layer can be stably maintained for a long time under high load by filling and coating the friction layer between the two materials, the persistence is obviously enhanced, and the titanium alloy has more excellent friction and wear performance.
However, the friction reducing component is not as much as it is, and example 2 adds more polyvinyl alcohol, and the friction layer cannot improve the frictional wear properties of the titanium alloy because of its non-load bearing capacity. The proportion of antiwear component and antifriction material is therefore appropriate, and the lubricity is optimized only if the friction layer has sufficient load-bearing capacity. Therefore, the proportion of antifriction and antiwear components in the nano mixed material has a better range, and the comprehensive performance of wear resistance and friction resistance is better than that of example 3 and example 1 and is better than that of example 2. Embodiment 4 is the most preferred embodiment.
The above examples are of several preferred embodiments of the invention, the scope of which is defined by the claims.
