The erosion of body, how to reduce marine organisms attach caused by biodeterioration the problems such as, realize the standby energy-saving and emission-reduction of extra large frock, drop energy
Synergy, the demand such as increase the service life, and is that industry is urgently thought deeply and solved the problems, such as.
Seawater is a kind of strong dielectric solution, along with more heavy corrosions such as freeze thawing, sea fog, typhoon, heavy rain, industrial emissions
The comprehensive function of environment, cause marine corrosion phenomenon.According to measuring and calculating, in the steel that China is soaked by ocean, just have within every 1 second
1.5 tons of steels are corroded；In addition, the particles such as silt are mingled with seawater, in tide, navigate etc. during, accelerate steel
Attrition.In addition, substantial amounts of marine organisms are grown in marine environment, including animal, plant and the major class of microorganism 3, wherein,
A part of marine organisms are liked being attached on the works such as ship, are referred to as fouling organism, have about 4000 kinds to be stained in ocean
Biology；Under suitable growth conditions, marine fouling organism and microorganism adsorption alow with marine facility platform growth and breeding,
And accelerate the corrosion of metal material.According to investigations, China's economic loss caused by corroding and being stained accounts for gross national product
4%.Therefore, for ocean steel construction, shipping industry, a kind of anti-corrosion good wear-resisting/anti-attrition and anti-pollution function of having concurrently of development

Have：HVAF, flame-spraying, explosive flame spraying, Ultrasonic Arc Sprayed etc..
Above-mentioned thermal spraying surface treatment method has features, and different modes can be used to adapt to different metal material tables
Face performance requirement, but there is also some limitations during use, for example, using HVAF WC bases (WC-
12Co, WC-Co-Cr etc.), the material such as HastelloyC is Ni-based, for the design of ship steel structure surface abrasion resistance anti-corrosion coating, if
Standby expense is too high, and cost of material is expensive.At present, Arc sprayed Al, Zn or Al/Zn seal up the Organic-inorganic Hybrid Protection Coating in hole in marine steel knot
It is most widely used in structure, shipping industry.But the abrasive particles such as the silt often carried secretly in actual applications in by current and water are to applying
Layer produces abrasion, greatly destroys anti-corrosion coating, ultimately results in coating failure.The attaching of marine organisms simultaneously, causes serious
Marine biofouling problem, the corrosion of accelerated material or the failure of coating, ultimately result in extra large work equipment performance decline to a great extent, the longevity
Order serious curtailment.Therefore, it is necessary to which a kind of low cost, efficient, corrosion-proof wear/anti-attrition have the protective coating and its table of anti-pollution function concurrently
Face treatment technology.
