次に、この発明の実施例を、被塗物として鋼板を用いて
ガラス状被膜を形成する場合について述べる。なお、こ
の例は他の金属被塗物についても応用できるものである
ことはいうまでもない。(Example) Next, an example of the present invention will be described in which a glass-like coating is formed using a steel plate as the object to be coated. It goes without saying that this example can also be applied to other metal objects.
まず、前処理として通常なされるプラスト処理工程につ
いて説明すると、金属よりなる被塗物表面に公知の硬質
微粒子によるブラスト処理が通常なされる。このブラス
ト処理は被塗物表面に微細な凹凸を付与して結合面積を
増大しもって被膜の接合強度を向上させる目的でなされ
る。また、被塗物表面の汚れや錆等を除去するクリーニ
ング作用もある。First, a blasting process which is usually performed as a pre-treatment will be explained.The surface of a metal object to be coated is usually subjected to a blasting process using known hard fine particles. This blasting treatment is carried out for the purpose of imparting fine irregularities to the surface of the object to be coated to increase the bonding area and thereby improve the bonding strength of the coating. It also has a cleaning effect that removes dirt, rust, etc. from the surface of the object being coated.
下地材の溶射工程は必要に応じ付加される。A thermal spraying process for the base material is added as necessary.
すなわち、金属特に鉄金属が高温で加熱されると該金属
表面には酸化鉄が形成され、この酸化鉄は適度に形成さ
れるときにはその後形成されるガラス被膜との結合強度
を増すので好ましいが、しかしながら、例えば４００℃
以上の高温で予熱される場合には該金属表面に酸化第一
鉄さらには酸化第二鉄が過刺に形成され、これが後に形
成されるガラス被膜を剥離させる大きな原因となる。That is, when a metal, particularly an iron metal, is heated to a high temperature, iron oxide is formed on the surface of the metal, and when this iron oxide is formed in an appropriate amount, it increases the bonding strength with the glass coating that is subsequently formed, so it is preferable. However, for example, 400℃
When the metal is preheated at a higher temperature, ferrous oxide and even ferric oxide are formed in excess on the metal surface, which is a major cause of peeling off the glass coating that is formed later.
そこで、次工程で、予熱温度が高温１例えば４ＯＯ℃以
上となるような場合には、あらかじめステンレス、ニッ
ケル合金等の下地材を溶射して５０〜３００ル程度の酸
化防１ｈ膜を形成しておくことが好ましい、下地材とし
ては酸化しにくいもので、上のステンレス、ニッケル合
金、クロム合金のほか１ｍ化ニッケル、酸化コバルト、
酸化アルミニウム、酸化ジリコニウム等を使用すること
ができる。Therefore, in the next process, if the preheating temperature is high temperature 1, for example, 400°C or higher, a base material such as stainless steel or nickel alloy is sprayed in advance to form an oxidation prevention film of about 50 to 300 l. It is preferable to use a material that is difficult to oxidize as a base material.
Aluminum oxide, zirconium oxide, etc. can be used.
なお、下地材に関連して、被塗物がアルミニウムの場合
、アルミニウムは融点が低く高熱で溶融しや、すいので
、酸化アルミニウムを溶射して下地材として耐熱被膜を
形成しておくことは好ましくすすめられる。Regarding the base material, if the object to be coated is aluminum, it is preferable to thermally spray aluminum oxide to form a heat-resistant coating as the base material, since aluminum has a low melting point and easily melts under high heat. Recommended.
次に、予熱工程について説明すると、被塗物となる鋼板
を１００１以上に予熱する。この予熱はバーナーによる
加熱でもよいが、加熱炉に入れて行なってもよい、予熱
温度はすくなくとも１００１以上、溶射材料あるいは他
の条件により溶射温度まで加熱することができる。Next, to explain the preheating step, the steel plate to be coated is preheated to a temperature of 1001 or higher. This preheating may be performed by heating with a burner, or may be performed in a heating furnace.The preheating temperature may be at least 1,001 or higher, and heating can be performed up to the spraying temperature depending on the spraying material or other conditions.
予熱温度を１００℃以上としたのは、被塗物表面に水分
が残留すると形成されるガラス状被膜に悪影響を与える
ということと、実験の結果、溶射材料あるいは他の条件
にもよるが慨ね１００℃程度から良好な溶融状態が得ら
れることによる。The reason for setting the preheating temperature to 100℃ or higher is that if moisture remains on the surface of the object to be coated, it will have an adverse effect on the glass-like film that is formed, and as a result of experiments, it generally depends on the spraying material and other conditions. This is because a good melting state can be obtained from about 100°C.

である０次に溶射条件の一例を示す。After the preheating step, a glass spray material is sprayed onto the preheated surface of the object. This thermal spraying was carried out by plasma spraying in the example, but an example of zero-order thermal spraying conditions will be shown which is also possible by gas spraying or the like.

る。Example (Weight %) Next, the effects of each composition of the above glass thermal spraying material will be briefly explained. SiO2 is the main glass-forming oxide,
Significant influence on coefficient of thermal expansion, softening point and wear resistance. In addition, the higher the amount of S i 02 ik, the higher the abrasion resistance, weather resistance, and acid resistance, and the better the performance of the glass film. However, if the amount is too high, the fire resistance of the glass material increases and the spraying temperature must be increased. It will stop happening. Therefore, in order to lower the preheating temperature of the object to be coated, the SiO2 should be 30 to 70.
%. The more B2O3 there is, the worse the abrasion resistance, weather resistance, and acid resistance will be, but on the other hand, the glass fire resistance will be lowered. In view of the relationship with other components in the present invention, about 5 to 30% is preferable. When B2O3 is increased, melting occurs quickly in the flame of the thermal spraying device.

る。The reason why 5 to 20% of L I 20 is added is to increase the electrical resistance of the product, increase the hardness, and improve chemical durability, especially acid resistance. Furthermore, since the coefficient of expansion is large, it can be adjusted to match the coefficient of expansion of the base material by a small amount of adjustment. Replacing the powder with L 120 lowers the specific gravity, increases the coefficient of thermal expansion, increases fluidity, lowers the melting temperature, and lowers the softening and solidification temperatures. Therefore, it is desirable to add as much as the expansion coefficient allows; the more it is, the faster it will melt in the frame, and the more gloss it will have.

AfL203 is added in a range of 1-10%.

The reason for adding 0 to 20% of one or more of ao and F2 (1 weight) is that the fire resistance of the glass material can be lowered by the synergistic effect of the main component and additives. These additives also allow the glass material to melt more quickly during thermal spraying.

た任意にいれることもある。CaO acts as a fluxing agent and improves chemical durability. i.e. it increases its resistance to the dissolving action of water, it also increases its hardness and therefore its resistance to abrasion and weathering action, and it also increases its tensile strength and significantly reduces its coefficient of expansion when compared to alkaline action. Cracks can be prevented. In addition, SrO, which lowers the viscosity when melted, also acts as a flux, increasing fluidity, lowering the softening temperature, and increasing the degree of melting.
When substituted with rO, the reaction with the base material is promoted, the adhesion of the glass material is improved, and the peel strength is also increased. N

膜中にカーボンが付着することを防止する。ZnO acts as a solvent, imparting gloss to the glass material, limiting the action of one chromophore, and sometimes imparting emulsivity. However, since the viscosity increases significantly, it is not possible to add much. Also, when both ZnO and SrO are used, the fluidity of the glass increases, making it easier to produce a smooth glass surface and reducing pinholes. Further, since ZnO prevents the glass material from shrinking, it prevents the glass material from peeling off as a result of shrinkage, and also prevents carbon from adhering to the glass coating during thermal spraying.
