Abstract
The invention provides an anti-rust layer for a hexagonal shaft. The anti-rust layer for the hexagonal shaft comprises a hexagonal shaft body and a metal coating arranged on the surface of the hexagonal shaft in a coating manner. The thickness of the metal coating is 0.2-0.4 mm. The metal coating comprises, by weight, 75%-80% of aluminum powder, 5%-10% of zinc powder, 1%-3% of nickel powder, 3%-4% of bonding agent and 4%-8% of dispersing agent. The average grain size of the aluminum powder, the zinc powder and the nickel powder is 300-500 nm, sizing is prepared after the aluminum powder, the zinc powder and the nickel powder are mixed, ground and dispersed at a high speed, and the sizing is sprayed on the hexagonal shaft under a high temperature to form the metal coating. The temperature of high-temperature spraying is 2000-3000 DEG C. The anti-rust layer for the hexagonal shaft is easy to manufacture and low in cost, coating is convenient, the anti-rust effect is good, and the service life is long.
Description
Technical field
The present invention relates to a kind of metallic coating, particularly a kind of hexagonal axis rustproof layer.
Background technology
Hexagonal axis is a vitals on trolley part, and it is welded by right cylinder and hexagonal axis body.Before hexagonal axis dispatches from the factory, antirust treatment need be carried out to the surface of hexagonal axis, to increase the service life.Traditional rustproof layer rust-proof effect is poor, the life-span is short.
Summary of the invention
The technical problem that [1] will solve
The technical problem to be solved in the present invention is to provide the hexagonal axis rustproof layer of a kind of favorable rust preventing effect, life-span length.
The technical scheme of [2] dealing with problems
The invention provides a kind of hexagonal axis rustproof layer, it comprises hexagonal axis body and is coated in the metallic coating on described hexagonal axis surface, and described metallic coating thickness is 0.2-0.4mm, and the weight percent of its composition is:
Aluminium powder 75%-80%;
Zinc powder 5%-10%;
Nickel powder 1%-3%;
Binding agent 3%-4%;
Dispersion agent 4%-8%;
The median size of described aluminium powder, zinc powder, nickel powder is 300-500nm, and described aluminium powder, zinc powder, nickel powder, binding agent, dispersion agent obtained slurry after mixing, grinding, high speed dispersion, described slurry forms described metallic coating through pyrolytic coating on described hexagonal axis body; The temperature of described pyrolytic coating is 2000-3000 DEG C.
[3] beneficial effect
Hexagonal axis rustproof layer of the present invention, make simple, cost is low, coating is convenient, favorable rust preventing effect and the life-span long.
Embodiment
Introduce the embodiment of the present invention in detail below.
The invention provides a kind of hexagonal axis rustproof layer, it comprises hexagonal axis body and is coated in the metallic coating on described hexagonal axis surface, and described metallic coating thickness is 0.2-0.4mm, and the weight percent of its composition is:
Aluminium powder 75%-80%;
Zinc powder 5%-10%;
Nickel powder 1%-3%;
Binding agent 3%-4%;
Dispersion agent 4%-8%;
The median size of above-mentioned aluminium powder, zinc powder, nickel powder is 300-500nm, and aluminium powder, zinc powder, nickel powder, binding agent, dispersion agent obtained slurry after mixing, grinding, high speed dispersion, slurry forms metallic coating through pyrolytic coating on hexagonal axis body; The temperature of pyrolytic coating is 2000-3000 DEG C.
Hexagonal axis rustproof layer of the present invention, make simple, cost is low, coating is convenient, favorable rust preventing effect and the life-span long.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
