The invention relates to a powder-coated spinning wire used for a main cable of a suspension bridge and a fabrication method thereof. The powder-coated spinning wire has a shot-blasted plating layer and a powdered coat formed in their order on a core wire. The plated core wire is shot-blasted to roughen the plating layer and remove an oxide layer. Then, the core wire is first heated, sprayed with powder paint, and second heated. The plating layer is formed at an amount of 50 g/m2 to 300 g/m2, and the powdered coat has a thickness ranging from 10 μm to 400 μm. The powder-coated spinning wire has corrosion resistance and endurance improved. Since heated powder coating is adopted instead of electrostatic powder coating, powder coating equipment can be simplified and the productivity of the powder coating can be improved also.

摘要:
A method of coating of steel products such as plate and sheet using an aluminum-zinc coating alloy includes modifying the coating bath with a particulate compound constituent in effective amounts to control the spangle facet size of the coated product, improve tension bend rust stain performance, and improve coated product paintability. Constituents include borides such as titanium boride and aluminum borides, carbides such as titanium carbide, and aluminides such as titanium aluminide. The method produces a coated steel product that does not require temper rolling for painting.

摘要:
A method of treating a metal layer present as a coating on a sheet metal substrate, wherein a powder is applied to said metal coating by propulsive means (e.g., spraying or the like) when said coating is at least partially in the liquid state. The powder is prepared by atomization in a manner adapted such that the powder is in the form of agglomerates having a mean diameter which is greater than the thickness of said liquid-state metal coating. With this use of this powder, it is easier to treat metal coatings in the liquid state, and the resulting treated coating is highly homogeneous, even if the atomized powder has a plurality of types of components.
摘要:
A method and device of performing plating of an item having a row of fine parts, e.g. a flatpack IC are disclosed. The method comprises immersing said item in a bath of molten solder, removing said item from said bath while maintaining said item in an attitude such that said row of fine parts is sloped with respect to the surface of said molten solder, and causing flux to exert a fluxing action on said molten solder which adheres to said fine parts, thereby decreasing the surface tension of the solder adhering to said fine parts and preventing bridges of solder from forming between said fine parts.
摘要:
An apparatus for the treatment of galvanized sheet-iron emerging from a galvanization bath in order to reduce to a minimum value the size of the "minispangle" appearing on its surface comprises a housing divided into two identical casings spaced to form a vertical passage through which the sheet is caused to travel continuously, each casing comprising a spray nozzle and a pair of recovery slots disposed on either side of the nozzle, and blower means for directing an air stream loaded with zinc particles in suspension against the moving sheet surfaces so that the zinc particles will crystallize before the liquid zinc coating has set. The blower means produces the stream and recovers on its section side the previously blown air. Passages in the casings direct the air stream towards the spray nozzle and from the recovery slots.

摘要:
The invention concerns a method of producing a coated ferrous substrate having improved spot welding characteristics comprising introducing a ferrous substrate into a bath of molten metallic coatant so as to coat the substrate therewith, withdrawing the coated substrate from the bath, and thereafter directing particles of metallic iron or iron-based alloy onto the coated substrate, before the molten coatant thereon solidifies, so that the particles are retained adjacent the surface of the coatant during solidification of the latter.
