実際に行なつてみないと不明である場合が多い。(Prior Art) It is well known that there is an enamel method as a technique for coloring and coating the surface of a base material, but this method has the disadvantage that it cannot be applied to concrete, wood, etc. because it heats the base material. Thermal spraying is a technique to improve this drawback. Thermal spraying has the advantage of not only being able to coat the surface of a base material without changing the properties of the base material, but also providing heat resistance, corrosion resistance, and abrasion resistance by coating ceramics. Currently, there are very few types of color thermal spray coating materials that not only have these functions but also have decorative elements that give them an aesthetic appearance. For example, Al 2 O 3・
TiO 2 , white Al 2 O 3 , exhibits cobalt blue color
Examples include Al 2 O 3 and CoO. The reason for this is the fact that the color development of the thermal spray material before and after the thermal spraying process is not necessarily the same. In particular, when ceramic spraying is carried out using the plasma method, the plasma is generated in a reducing atmosphere, so there are more oxygen vacancies than in a normal crystal lattice state, which causes color absorption, which causes problems in the sprayed ceramics. This is thought to be because the overall color tone is different from the color tone of the ceramics before thermal spraying. Furthermore, since thermal spraying is rapidly cooled from a high temperature state, the unstable state at a high temperature is brought to a room temperature state while being fixed, so it is thought that the crystalline state is different from the crystalline state that is slowly cooled from a high temperature state. Therefore, it is extremely difficult to predict the color tone obtained as a result of thermal spraying before thermal spraying, and it is often unclear until thermal spraying is actually performed.
しかし溶射に当つては溶射後における溶射被覆
の色調を溶射前に予知しておき、希望の色調に合
せた溶射を提供することは重要である。 However, in thermal spraying, it is important to predict the color tone of the thermally sprayed coating before thermal spraying, and to provide thermal spraying that matches the desired color tone.

被覆材を提供することにある。(Object of the Invention) In view of the problems of thermal spraying technology as described above, the present invention provides a thermal spraying material that does not damage the substrate to be thermally sprayed, has corrosion resistance and abrasion resistance, and can adjust the color of the thermal spray coating.
The object of the present invention is to provide a thermal spray coating material that develops a greenish-brown color, which is particularly desired for building materials.

Even when it becomes Al 2 O 3 6SiO 2 , it exhibits the emerald color of beryl. Furthermore, MnO itself exhibits a green color, and when it is combined with CaO and SiO 2 , it also exhibits a green color. Sapphire, ruby, spinel, quartz, etc., both known as natural and artificial gems, are all due to the unique colors of the metal oxides they contain.

ることが極めて困難である。 However, thermal spraying materials are thermally sprayed at high temperatures, and the thermal spraying materials are mixtures or compounds of one or more metal oxides, and when these are thermally sprayed at high temperatures, such as plasma spraying, as mentioned above, plasma The color tone of the thermal spray material before thermal spraying is not necessarily the same as the color tone before thermal spraying because a part of the composition is affected by some discoloration at high temperatures. Therefore, in the case of color thermal spraying on a base material to be thermally sprayed, it is extremely difficult to predict in advance the color of the thermal spray coating on the finished surface.
本発明は斯様な困難を緑色系統の溶射材の組成
を特定することによつて溶射後の被覆表面色調を
予め設定できるようにしたものである。 The present invention overcomes these difficulties by specifying the composition of the green thermal spray material, thereby making it possible to preset the color tone of the coated surface after thermal spraying.

見当らない点から見ても本発明の溶射材は独特な
組成であると云える。 This thermal spraying material is mainly used for the decorative effect of adding beauty to buildings made of wood, concrete, etc., and is therefore often applied to areas where heat resistance is not a major concern. Therefore, ZnO can be added, and the addition of ZnO has the effect of deepening the color of CoO. The thermal spraying material of the present invention can be said to have a unique composition since no conventional thermal spraying material contains ZnO.
CoOの組成が１〜20重量％に限定される理由お
よびZnOの組成が20〜79重量％に限定される理由
はこれらの範囲外の領域では、目的とする緑色発
色の色度調節の限界を越えるためであり、しか
も、却つて濃緑色が美観を損うためである。 The reason why the CoO composition is limited to 1 to 20% by weight and the reason why the ZnO composition is limited to 20 to 79% by weight is that outside these ranges, the limit of chromaticity control for the desired green coloring is reached. This is to overcome the problem, and moreover, the dark green color spoils the beauty.
上記の範囲においてCoOを１％から20％まで、
ZnOを20％から79％まで変えることにより緑色を
淡緑色から濃いモスグリーンに至る各色濃度に調
節することができる。 CoO from 1% to 20% within the above range,
By changing the ZnO content from 20% to 79%, the green color can be adjusted to various color densities from light green to deep moss green.
TiO2の組成が20〜60重量％に限定される理由
はTiO2の組成変化によつて溶射面の粗度、硬度
に変化を生じ、とくに溶射面の硬度において
TiO220重量％以下では硬度不足を生じ、また60
重量％以上となるとTiO2の黒色により緑色にな
らないためである。 The reason why the composition of TiO 2 is limited to 20 to 60% by weight is that changes in the composition of TiO 2 cause changes in the roughness and hardness of the sprayed surface, especially in the hardness of the sprayed surface.
If TiO 2 is less than 20% by weight, hardness will be insufficient, and 60% by weight or less will result.
This is because if it exceeds % by weight, the black color of TiO 2 prevents it from becoming green.

and TiO 2 are each blended in single fine particles, or granulated with a primary binder, or CoO, ZnO, and TiO 2 with the above composition.
It is possible to solidify the melt, crush it, and classify it.
