Description
Technical field
The present invention relates to indium iron netted ball compound crystallite composite bed.
Background technology
Fretting wear is the one of the main reasons of the product failure such as machinery and automobile, and the component of machine of about 80% lost efficacy because various forms of wearing and tearing cause, and brought economic loss to reach tens yuan because component of machine loses efficacy.
Literature search and patent search result, domestic also not containing the Patents reported in literature of the indium iron netted ball compound crystallite composite bed of indium amount more than 50% at present.
Summary of the invention
Task of the present invention is to provide a kind of indium iron netted ball compound crystallite composite bed, task of the present invention is achieved by the following technical solution: indium iron netted ball compound crystallite composite bed of the present invention establishes a surface material layer at part, surface material layer Main Ingredients and Appearance be containing indium more than 50% (Wt%) and the total content of indium and iron more than 55% (Wt%), be closely connected by the spheric grain or approximate sphericity crystal grain that are no less than 4 and form the larger indium iron composite balls microcrystal unit of volume and distribute and form grid, the single crystal grain that in grid, solid matter is many or be closely connected form small volume indium iron microcrystal unit by being no less than 2 spheric grains or approximate sphericity crystal grain, piece surface material layer becomes to be integrated with matrix material, forms indium iron netted ball compound crystallite composite bed.
Mesh shape and the size of described indium iron netted ball compound crystallite composite bed can change.
Present inventor is through further investigation for many years, find in machinery part surface generation relative movement, especially there is the machine components contact surface of fretting wear, the minimizing fretting fatigue of indium iron netted ball compound crystallite composite bed, fretting corrosion performance with surface of friction pair can be made in time to form lubricating oil film, form the mechanism of action of hydrodynamic lubrication, to mantle friction factor and the frictional force mechanism of action of improving its contact surface, have a great difference with mostly several Chinese scholars associated materials performance led of having appeared in the newspapers.Indium iron netted ball compound crystallite composite bed can effectively reduce fretting fatigue, fretting corrosion, especially can significantly improve the performance of the anti-Compound Fretting Wear such as " radial fretting+torsion fine motion " and " tangential fretting+rotary micromotion " on feature contacts surface simultaneously, have and keep the contact condition of piece surface and the Compound Fretting Wear that obviously improves its approximate original position contact, the microdefects such as the relaxation that existing correlation technique or technique etc. causes contact surface to cause can be overcome, and improve the performance such as fretting fatigue, fretting corrosion of contact surface simultaneously.Therefore, study indium iron netted ball compound crystallite composite bed and there is important using value and Practical significance.
Compared with the prior art, indium iron netted ball compound crystallite composite bed of the present invention correlation technique have significant improvement: structure and material two aspect significant improvement that 1. can significantly improve the performance of the anti-Compound Fretting Wear such as " radial fretting+torsions fine motion " and " tangential fretting+rotary micromotion " on feature contacts surface simultaneously: piece surface material layer be mainly by contain indium more than 50% (Wt%) and the total content of indium and iron more than 55% (Wt%), be closely connected by the spheric grain or approximate sphericity crystal grain that are no less than 4 and form the larger indium iron composite balls microcrystal unit of volume, the indium iron composite balls microcrystal unit that many volumes are larger distributes composition grid according to certain rules, in grid solid matter many containing indium more than 50% (Wt%) and the total content of indium and iron more than 55% (Wt%) single crystal grain or be closely connected form small volume indium iron microcrystal unit by being no less than 2 spheric grains or approximate sphericity crystal grain, having the rare performance that simultaneously can significantly improve the anti-Compound Fretting Wear such as " radial fretting+torsion fine motion " and " tangential fretting+rotary micromotion " on feature contacts surface of other structure, there is significant improvement in the structure of indium iron netted ball compound crystallite composite bed and material two aspect all, 2. indium iron netted ball compound crystallite composite bed can effectively reduce fretting fatigue, fretting corrosion, 3. have and keep the contact condition of piece surface and the Compound Fretting Wear that obviously improves its approximate original position contact, stressed and the deformation mode of indium iron netted ball compound crystallite composite bed and the bearing load of the crystal grain on common parts surface and deformation mode of net distribution have substantive different, the heat engine coupling of the crystal grain of indium iron netted ball compound crystallite composite bed, hot-fluid coupling lubrication, promotion form lubricating oil film, and reducing wear principle has substantive different from the operation principle that general surface is lubricated, 4. the lubrication form of compound: in the relative movement of machine components, containing indium more than 50% (Wt%) and the total content of indium and iron is more than 55% that (Wt%) material has good self-lubricating property, the intercrystalline of indium iron netted ball compound crystallite composite bed has store oil self-lubricating property, the lubrication form of compound is formed together with oil lubrication, improve greasy property, tool has clear improvement the tribological property of friction pair of machine components contact surface, thus effectively reduces the fretting wear of friction pair, 5. absorbing antifriction: the crystal grain energy absorption portion vibration of indium iron netted ball compound crystallite composite bed, the absorption portion had the machine components that there is fretting wear is vibrated, reduce because the insufficient fretting wear of existence lubrication has significant application value, it is lasting that indium iron netted ball compound crystallite composite bed has unique minimizing fretting wear effect effect to the machine components contact surface that there is fretting wear, therefore, the crystal grain of indium iron netted ball compound crystallite composite bed of the present invention has important using value and Practical significance.
The invention has the beneficial effects as follows, can effectively reduce fretting fatigue, fretting corrosion, especially can significantly improve the performance of the anti-Compound Fretting Wear such as " radial fretting+torsion fine motion " and " tangential fretting+rotary micromotion " on feature contacts surface simultaneously, the fretting wear on the energy mechanical feature contacts surface of permanently effective minimizing, easy to use, structure is simple, and applicability is strong, and application cost is suitable for, be applicable to the feature of batch production.
