Description
Technical field
The present invention relates to aseptic technic, more particularly to a kind of method of electric arc spraying corrosion-inhibiting coating.
Background technology
For corrosion mechanism, coastal engineering ship is primarily present two kinds of works of electrochemical corrosion and seawater corrosion using process
With.
Electrochemical corrosion refer to the medium of metal surface and ionic conduction because electrochemical action occurs and caused by destruction.Its
Two processes that are relatively independent and can carrying out simultaneously can be divided into by being mainly characterized by its reaction mechanism mechanism of reaction --- cathode reaction and
Anode reaction.It is mainly characterized by between metal and electrolyte that there is a powered boundary layer.
Seawater corrosion refers to the corrosion of the equipment used in marine environment and facility.Saliferous highest in seawater, into split pole
It is complicated, is corrosive electrolyte.It can prevent and destroy containing the chlorion of higher concentration and other halide ions in seawater
The passivation of metal, anodic process is set to be easier to carry out.Under the conditions of the pH value of seawater, seawater corrosion is oxygen depolarization process, negative electrode
The speed of corrosion reaction in process control.In addition, seawater velocity, marine organisms etc. also often influence seawater corrosion it is important because
Element.
Corrosion in various environment is extremely complex, different degrees of influence to various equipment all be present, mainly has following several
Individual aspect.
1. metal material whole surface or local thickness is caused to be thinned, so as to influence its intensity, rigidity and mechanical-physical
Energy；
2. movement pair surface erosion corrosion aggravates, make the increase of movement pair surface roughness, so as to resistance, influence even
Damage the expectation function of Working mechanism；To there is the movement pair surface of seal request (such as oil cylinder) that sealing property reduction occurs；
Phenomena such as aperture increases or gap broadens occurs for the position of connection；
3. under the effect such as air, seawater leaching, salt fog, electrochemistry, electric conductivity declines electrical equipment, equipment is caused to exist
It is disabled during use, it is impossible to normal operation；
4. the regional area of metal occur from table and in corrosion cracking, lead crack is mutually perpendicular to tensile stress.In master
During dry crack growth, also some branch development, so as to form stress-corrosion cracking；
5. metal material declines fatigue life under corrosive medium and alternate stress collective effect.
The content of the invention
It is an object of the present invention in view of the above-mentioned problems, propose a kind of method of electric arc spraying corrosion-inhibiting coating, general paint
Bond strength be 10-15MPa, and be affected by human factors larger, and arc spraying technology makes moderate progress in this respect.
To achieve the above object, the technical solution adopted by the present invention is：A kind of method of electric arc spraying corrosion-inhibiting coating, including
Following steps：
1. sprayed on material is heated, fusing；
2. the sprayed on material melted is atomized；
3. the injection flight of the subparticle of melting or softening；
4. particle is collided in substrate surface, deforms, solidified.
Further, electric arc spraying can only spray conductive material.
Further, the sprayed on material is zinc-chromium coating.
Further, the sprayed on material is Ni-P amorphous alloy coatings.Electroless Plating Ni-P coating and carbon steel part
When being combined and forming corrosion cell, coating is negative electrode without being corroded.Therefore, for carbon steel, Electroless Plating Ni-P amorphous
Steel components are had superior isolation antisepsis by state alloy layer category cathodic coating.
Another object of the present invention also discloses a kind of electric arc spraying corrosion-inhibiting coating, is prepared using the above method.
A kind of method of electric arc spraying corrosion-inhibiting coating of the present invention, compared with prior art with advantages below：
The construction technology of electric arc spraying is simpler, i.e.,：It is surface-treated --- electric arc spraying --- encapsulation process.Electric arc spraying
Key is to be surface-treated, and surface should be dried after general surface treatment, free from dust, greasy dirt, oxide skin, rusty stain etc., surface cleaning
Spend Sa3.0, roughness Rz：40—80μm.Surface after processing should carry out electric arc spraying within 4h, in order to avoid sand blasted surface oxygen
Change, cause coating binding force to decline；Seal treatment can be divided into twice, wherein first of seal coat all infiltrates into coating space
In, play sealing process；Second finish paint plays further sealing process and smooth, while has anti-external environment corrosive
Property.
