Abstract
The utility model discloses a metal part with a self-repairing material coating, which comprises a machine-shaped metal substrate and the self-repairing material coating. Self-repairing material powder is coated on the surface of the metal substrate through spraying process to form the self-repairing material coating, and ingredients of the self-repairing material coating are identical to those of metal part illuminating oil. As the self-repairing material powder is coated on the surface of the machine-shaped metal substrate to form the self-repairing material coating by means of adopting the spraying process directly, sedimentation and separation can be avoided. The ingredients of the self-repairing material coating are identical to those of the metal lubricating oil, the metal part adopted as the fast coagulation technology is used for preparing thicker coatings with thickness over tens of microns and even reaching several millimeters, does not change physicochemical performance indexes of the lubricating oil and resolves the difficult problem of distribution of self-repairing additive and lubricating oil.
Description
Technical field
The utility model belongs to the machinery part surface treatment technology, particularly a kind of metalwork with self-repairing material coating.
Background technology
The selfreparing Technology of mechanical component frictional wear has at present become the research focus of process for treating surface; this Technology is to be that the superfine powder of main additive adds in the lubricating oil with self-repair material such as hydroxy silicate; in equipment running process with iron-based body generation chemical reaction; form the sintering metal protective layer of anti-attrition excellent performance, realize original position selfreparing wear metal.Adjust the composition of self-repair material simultaneously, not only have wear-resisting, compensate for wear and hard effect of repairing, and can obtain super lubricating property, good antifriction function and the effect of soft reparation; Frictional coefficient is very low, can obtain the frictional coefficient than the low order of magnitude of fluid oil film lubrication.
But in the existing method,, there is following problem owing to use silicate powder as additive of self-rehabilitation:
1, additive of self-rehabilitation is mainly the silicate inorganic powder, because of preparation method's difference, obtains the coacervate about 1～10 μ m, add lubricating oil after, be easy to generate precipitation and separate, influence the self-reparing capability of self-repair material;
2, because the selfreparing powder additives adds in the lubricating oil, change the physical and chemical index of lubricating oil simultaneously, had the compatibility problems of additive of self-rehabilitation and lubricating oil;
3, the repairing effect of additive of self-rehabilitation is relevant with the friction pair system, and different loads, temperature, speed all have bigger influence to self-repair procedure.
Summary of the invention
For solving the problems referred to above that prior art exists, the purpose of this utility model is a kind of physical and chemical index that does not produce precipitate and separate, do not change lubricating oil of design, forms the metalwork with self-repairing material coating that ceramic film is protected in selfreparing at the fricting couple piece surface in situ.
To achieve these goals, the technical solution of the utility model is as follows: a kind of metalwork with self-repairing material coating, the metallic matrix and the self-repairing material coating that comprise machine-shaping, described self-repairing material coating is the self-repairing material coating that the self-repair material powder coating is formed on metal base surface by spraying coating process, and the composition of described self-repairing material coating is identical with the composition of metalwork lubricating oil.
The thickness of self-repairing material coating described in the utility model is generally at 0.1～9.9mm.
Self-repair material main ingredient described in the utility model is hydroxyl magnesium silicate or hydroxyl pure aluminium silicate.
Compared with prior art, the utlity model has following beneficial effect:
1, because the utility model directly adopts spraying coating process, the self-repair material powder coating on the surface of the metallic matrix of machine-shaping, is formed self-repairing material coating, therefore can not produce precipitation and separate.
2, because the composition of the utility model self-repairing material coating is identical with the composition of metalwork lubricating oil, (104～108K/s) are used to prepare thicker coating as a kind of flash set technology, thickness is above even reach several millimeters at tens of micron usually, do not change the physical and chemical index of lubricating oil, solved a difficult problem at the compatibility of additive of self-rehabilitation and lubricating oil;
3, the fricting couple piece that adopts the utility model to make, even does not handle on the surface, in process of friction and wear, coatingsurface contacts with the direct of fricting couple piece, self-repairing material coating can continually shift to even part surface, can carry out the coating reparation to the frictionally damage position, realize the manufacturing again of component of machine.
4, because the formation of transfer film of the present utility model can stop the material surface micro-bulge to contact with the direct of mating plate, increase loaded area, make perpendicular to the stress of line of travel and the quadrature shearing stress at point of contact place and all reduce, thereby suppress contact area germinating crackle, reduce the wear rate of material.
5, because the frictional coefficient between the utility model selfreparing rete is lower, have the self-lubricating effect, reduced the frictional wear between the friction pair.
6, owing to have certain hole in the spray-on coating of the present utility model, in process of friction and wear, can store certain lubricating oil, improve the lubricity under the condition of boundary lubrication.At present, also do not carry out the correlative study that thermospray prepares the selfreparing coating both at home and abroad.
7, metal current frictional wear self-repair technology becomes the research focus, and the research that spraying coating process prepares the application of self-repairing material coating becomes material, physics, chemistry, environmental protection field one and uses focus.Application of the present utility model can provide technical support in industrial large-scale application for the metal frictional abrasion self-repair technology.
8, metal current frictional wear self-repair technology becomes the research focus, and spraying coating process prepares self-repairing material coating becomes material, physics, chemistry, environmental protection field as the research of material surface engineering technology application an application focus.Application of the present utility model can provide technical support in industrial large-scale application for metallic rubbing pairs wear resistant friction reducing technology.
