本発明は溶射材に係り、特に安定性のある着色
溶射材に関する。DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention relates to thermal spray materials, and particularly to stable colored thermal spray materials.
(従来技術)
基材の表面を着色被覆する技術としてホウロウ
法は公知である。ホウロウ法は基材を加熱するた
めコンクリート、木材等には施工できない欠点が
ある。(Prior Art) The enamel method is known as a technique for coloring and coating the surface of a base material. The enameling method has the disadvantage that it cannot be applied to concrete, wood, etc. because it heats the base material.
この欠点を改善する技術として溶射法がある。
溶射法は基材の性質を変えることなく基材表面を
被覆できるのみならず、溶射材にセラミツクスを
用いることにより被覆に耐熱性、耐食性、耐摩耗
性を付与できる利点がある。 Thermal spraying is a technique to improve this drawback.
Thermal spraying has the advantage that not only can the surface of the substrate be coated without changing the properties of the substrate, but also heat resistance, corrosion resistance, and abrasion resistance can be imparted to the coating by using ceramics as the thermal spraying material.
上記の諸機能を有するほか、更に美観を与える

Al 2 O 3 , Al 2 O 3・CoO exhibiting cobalt blue color
An equal number of examples can be cited.

たがつて溶射の結果得られる色調を溶射前の溶射
材の見掛けの色調から予想することは極めて困難
であり、溶射を実際に行なつてみないと不明であ
る場合が多い。 The reason why there is so little colored thermal spray material is due to the fact that the color tone of the thermal spray material before and after thermal spraying is not necessarily the same. In particular, when spraying ceramics 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. It is believed that the overall color tone of the coating will be different from the color tone of the ceramic before spraying. Therefore, it is extremely difficult to predict the color tone obtained as a result of thermal spraying from the apparent color tone of the thermal spraying material before thermal spraying, and it is often unknown until thermal spraying is actually performed.
しかし溶射に当り、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
た溶射材を開発することは重要である。 However, when performing thermal spraying, it is important to predict the color tone of the thermal spray coating before thermal spraying and to develop a thermal spray material that matches the desired color tone.
(発明の目的)
本発明は、上記のような溶射技術の問題点にか

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 wear 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 yellow-green color, which is particularly desired for building materials.

ある。 It is well known that each metal oxide generally has a unique color. For example, beryllium oxide BeO itself is white;
When a compound is made with Al 2 O 3 , SiO 2 , etc., for example, 3BeO.Al 2 O 3.6SiO 2 , which has the composition of beryl, exhibits the pale green color of beryl. In addition, MnO itself exhibits a green color, which is similar to CaO.
It also exhibits a green color when it forms a compound with SiO 2 etc. Ruby, known as a natural and artificial gemstone,
Sapphire, spinel, quartz, etc. are all due to the unique coloring of the metal oxides that are their compositional components.

想定することは極めて困難である。 However, thermal spray materials are generally sprayed at high temperatures. Moreover, the thermal spray material is one or a mixture or compound of two or more metal oxides.
When these are subjected to high-temperature spraying, such as plasma spraying, as mentioned above, a part of the composition is affected by some kind of discoloration such as oxidation, reduction, compounding, phase transformation, etc. at the high temperature of the plasma, so the sprayed surface is The color tone of the material after it has been sprayed is not necessarily the same as the color tone before it was sprayed. Therefore, in the case of spraying a colored thermal spray material onto a base material to be thermally sprayed, it is extremely difficult to predict in advance the color development of the thermal spray coating on the finished surface.
本発明は斯様な困難を解決し、特に黄緑色系統
溶射材の組成を特定することにより溶射後の被覆

る。 The present invention solves such difficulties and makes it possible to predict the coated surface color tone after thermal spraying in advance by specifying the composition of the yellow-green thermal spray material.

ないので本発明溶射材は新規な組成物であると云
える。 This thermal spraying material is intended to provide a decorative effect that gives a beautiful appearance to objects to be thermally sprayed, especially buildings made of wood, concrete, etc. Therefore, it is often applied to areas where heat resistance is not particularly an issue. for that
It enables the addition of MgO, the amount of which is
A wide range of 5 to 40% by weight is possible.
The addition of MgO has the effect of deepening the color of CuO, and the concentration of yellow-green color is 5 to 40% by weight of MgO.
It is directly proportional to the amount of MgO added in the range of . Since no conventional thermal spraying material has such a composition ratio, it can be said that the thermal spraying material of the present invention has a novel composition.
CuOの組成が1〜20重量%に限定され、また
MgOの組成が5〜40重量%に限定される理由は
上記各限定値範囲を逸脱する領域では、目的とす

CuOとMgOを上記の範囲で調整することにより、
溶射後の被覆着色における黄緑色の濃度を調節で
きる。 The composition of CuO is limited to 1-20% by weight, and
The reason why the composition of MgO is limited to 5 to 40% by weight is that a yellow-green color with the desired aesthetic appearance cannot be obtained in a region outside of each of the above-mentioned limiting value ranges.
By adjusting CuO and MgO within the above range,
The yellow-green density in the coating coloring after thermal spraying can be adjusted.
Al2O3の組成が40〜94重量%に限定される理由
はAl2O3の組成変化に応じて溶射面の粗度および
硬度に変化を生じ、特にAl2O3組成が40重量%以
下では硬度不足を生じ、また94重量%以上では目
的とする色に発色しないからである。 The reason why the Al 2 O 3 composition is limited to 40 to 94% by weight is that the roughness and hardness of the sprayed surface change depending on the change in the Al 2 O 3 composition. If it is less than 94% by weight, the hardness will be insufficient, and if it is more than 94% by weight, the desired color will not be developed.

As a result of plasma spraying this thermal spray material onto the concrete base material surface,
The coated sprayed surface was given a beautiful appearance with a deep yellow-green color. The corrosion resistance and abrasion resistance were also superior to enamel and the like.
