n or the above with Cu, Nl, and Cr added. In the case of hot-dip plating, when the material to be plated is immersed in the plating bath, if there are too many TI, Mn, etc., there is a problem that wetting becomes worse and non-plating occurs, and there is a limit to the addition of additive components 1, but in the case of thermal spraying, Since wetting problems do not occur, the amount of additive elements added can be increased.

より容易に粉末状と為しつる。Therefore, the range of color development can be expanded and the hue can be maintained for a longer period of time. An example of a preferable thermal spray material is α1~2, 0wt
%Ti and optionally α01-4. 0 wt% Mn,
It is a zinc alloy containing at least one of Ca+Cr and Ni. Zinc alloy has good workability, so it can be easily processed into wires or rods, and it can also be easily made into powder by pulverization or droplet methods.
溶射装置としては、従来からガス火炎式溶射ガンとして

メッキのやりづらい隅々の部分もそこへガンの照準を向
けることにより容易にコーティングすることが出来る。In a thermal spray device, the thermal spray material is melted and sprayed onto the surface of the substrate to be coated. Since a thermal spray gun is used, even the corners that are difficult to coat with hot dip coating can be easily coated by aiming the gun there.

ロールされる。酸化の程度に応じて、黄色、暗赤色、緑
色、黄金色、紫色、青色等バラエティに富む色相を自在
に発色させることがで〜る。After thermal spraying, the degree of surface oxidation is controlled to obtain the desired coloration. Depending on the degree of oxidation, a wide variety of hues such as yellow, dark red, green, golden yellow, purple, and blue can be freely developed.

発色させることができる。To control this oxidation, the cooling rate of the thermal spray coating can be controlled using air cooling, water cooling, air cooling, etc., and the thermal spray coating can be controlled by using flame, infrared lamp, furnace (
If available, heating for various times and subsequent cooling can also be controlled. A desired hue can be developed by combining the composition of the thermal spray material and the surface oxidation state.
こうして、耐食性と彩色性とを併せ持つ亜鉛溶射コーテ
ィングが生成される。In this way, a zinc spray coating is produced that is both corrosion resistant and pigmented.
