Abstract
The utility model discloses an anticorrosion nano-coating structure of a valve. The anticorrosion nano-coating structure comprises a valve block (1). A nano-coating (2) and a TiCN coating (3) are sequentially disposed on the surface of the valve block (1). The nano-coating and the TiCN coating are coated on the surface of the valve block to form a multilayer coating structure, so that adhesion with the valve block is enhanced, the coating falls less easily, stability is improved, and the valve block has fine wear resistance and corrosion resistance. The nano structural layer on the surface of the valve block enlarges area of contact of the coating with the valve block, stress generated by difference in thermal expansion coefficient of the valve block and coating material can be decreased, and bonding strength of the coating is further improved.
Description
Technical field
The utility model relates to a kind of anti-corrosion nano coating structure of valve surface coating structure, particularly a kind of valve.
Background technique
At present, general one deck TiN ceramic layer that applies on the surface of conventional valve, the adhesion between this TiN ceramic layer and the valve is relatively poor, so that less stable, coating easily comes off, and coating structure is single, finally cause wear resistance and corrosion resistance all relatively poor, quality of product is not high.
The model utility content
The purpose of this utility model is, a kind of anti-corrosion nano coating structure of valve is provided.The utility model can improve coating adhesion, and difficult drop-off also improves wear resistance and corrosion resistance, guarantees quality of product.
The technical solution of the utility model: a kind of anti-corrosion nano coating structure of valve, comprise valve body, it is characterized in that: be provided with successively nano coating, TiCN coating on the described valve body surface.
In the anti-corrosion nano coating structure of aforesaid valve, described valve body is made of high silicon cast iron.
In the anti-corrosion nano coating structure of aforesaid valve, described TiCN coating is the TiCN composite ceramic layer.
In the anti-corrosion nano coating structure of aforesaid valve, the thickness of described nano coating and TiCN coating is the 3-5 micron.
Compared with prior art, the utility model is by coated with nano coating and TiCN coating on valve body surface, form a kind of laminated coating structure, the adhesion of enhancing and valve body is so that the coating difficult drop-off improves stability, also make it have good wear resistance and corrosion resistance, the nanostructured layers of valve body surface has increased effective area of contact of coating and valve body, and can reduce the stress that produces owing to valve body is different with the cladding material thermal expansion coefficient, further improves the adhesive strength of coating.Enforcement of the present utility model is simple in structure, and can apply the complex profile of valve body, and each coating thickness guarantees the valve accuracy of form and position at the 3-5 micron.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-valve body, 2-nano coating, 3-TiCN coating.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of anti-corrosion nano coating structure of valve consists of as shown in Figure 1, comprises valve body 1, and characteristics are: described valve body is provided with nano coating 2, TiCN coating 3 on 1 surface successively.
Described valve body 1 is made of high silicon cast iron.
Described TiCN coating 3 is TiCN composite ceramic layers.
The thickness of described nano coating 2 and TiCN coating 3 is the 3-5 micron.
The utility model is by coated with nano coating and TiCN coating on valve body surface, form a kind of laminated coating structure, strengthen the adhesion with valve body, so that coating difficult drop-off, improve stability, also make it have good wear resistance and corrosion resistance, the nanostructured layers of valve body surface has increased effective area of contact of coating and valve body, and can reduce the stress that produces owing to valve body is different with the cladding material thermal expansion coefficient, further improve the adhesive strength of coating.Enforcement of the present utility model is simple in structure, and can apply the complex profile of valve body, and each coating thickness guarantees the valve accuracy of form and position at the 3-5 micron.
