つきやすいという欠点は有している。(Prior Art) In recent years, metallic aluminum has been used in large quantities in a wide range of applications as a material for aircraft, ships, vehicles, building materials, and kitchen appliances. Although metal aluminum has the advantage of being lightweight, it has the disadvantages of a low melting point of 660°C, poor corrosion resistance, and low surface hardness. Therefore, in order to protect the surface of metal aluminum, the surface of metal aluminum is painted or an oxide film is formed on the surface like alumite. However, even if the surface of metal aluminum is painted or an oxide film is formed, it has the disadvantage that the surface is easily scratched.

点はある。 For this reason, enameling is applied to the surface of metal aluminum, but in this case, the frit, which is the molten component of the enamel, must have a lower melting point than the base metal, so it is usually heated to 550°C.
It is baked in a heating furnace such as an electric furnace or tunnel furnace at the following temperatures. There are two groups of low-melting point frits: lead-based and phosphoric acid-based, and lead-based frits, which have excellent corrosion resistance, are usually used.
However, lead-based frits are made of borax, quartz,
It is made from fluorite, feldspar, etc. as raw materials, mixed with nitrates and carbonates of metals such as alkali metals and alkaline earth metals, and oxides of lead, tin, zinc, nickel, and cobalt. Therefore, although metallic aluminum enamel made from these raw materials can have slightly improved corrosion resistance, it cannot be completely corrosion-resistant because it contains significant amounts of alkali, fluorine, boron, and lead. The disadvantage is that the strength and hardness of the enamel is not sufficient.

を目的とする。(Purpose of the Invention) The present invention provides a coating layer that has strength, hardness, fixing properties, corrosion resistance, heat resistance, and impact resistance that are significantly superior to aluminum enamel, and that coats the metal aluminum surface with oxygen-acetylene flame or plasma jet flame. An object of the present invention is to provide a thermal spray material for coating metal aluminum that can efficiently form a uniform coating layer when thermally sprayed.
(発明の構成)
本発明に係る金属アルミニウム被覆用溶射材は

ミニウムほうろうよりも著しく優れた被覆層が効
率よく均一に形成されるのである。(Structure of the Invention) The thermal spray material for coating metal aluminum according to the present invention has a composition of 50 to 54% by weight of SiO 2 , 30 to 40% by weight of MgO,
The frit is characterized by comprising 0.5-6% by weight of CaO, 1.5-5% by weight of Al 2 O 3 and 5-8% by weight of Fe 2 O 3 . This thermal spraying material for coating aluminum metal is applied to the surface of metal aluminum with oxygen.
When sprayed with an acetylene flame or a plasma jet flame, a coating layer with heat resistance, hardness, corrosion resistance, and adhesion significantly superior to that of aluminum enamel can be efficiently and uniformly formed.
ここで、SiO2が50重量%未満では良好なガラ
ス状態とならず、また54重量%を超えると粘性が
急速に上昇するので溶射されたものに繊維状物が
混在し均一な被覆面を形成しないので不適当であ
る。 Here, if SiO 2 is less than 50% by weight, a good glass state will not be obtained, and if it exceeds 54% by weight, the viscosity will increase rapidly, so fibrous substances will be mixed in the sprayed material and a uniform coated surface will be formed. It is inappropriate because it does not.
MgOは溶射被覆されるフリツトの膨張係数を
金属アルミニウムの膨張係数に近似させるために
30重量%以上必要であるが、40重量%を超えると
溶融温度を上昇せしめるので好ましくない。 MgO is used to make the expansion coefficient of the frit to be thermally sprayed close to that of metallic aluminum.
It is necessary to use 30% by weight or more, but if it exceeds 40% by weight, it is not preferable because it increases the melting temperature.
CaOはフリツトの溶融温度を下げるのに用いら
れるが、0.5重量%未満では効果が少なく、6重
量%を超えると粘性が急激に降下するので好まし
くない。 CaO is used to lower the melting temperature of the frit, but if it is less than 0.5% by weight it has little effect, and if it exceeds 6% by weight the viscosity drops rapidly, which is not preferred.
Al2O3は溶射初期に金属アルミニウムの表面に

着層を完成させる成分として作用するが、1.5重

ない。 Al 2 O 3 acts as a component that fuses with the thin aluminum oxide film that forms on the surface of metal aluminum during thermal spraying to complete an adhesion layer, but if it is less than 1.5% by weight, the fusion and adhesion effects are poor;
Exceeding this is not preferable because it increases the melting temperature.
Fe2O3は溶射した際、広範囲に、かつ急速に均
一な被覆層を生成させる。すなわち、加熱温度に
おける流動性を向上させる成分であるが、5重量

覆層の耐熱性、耐食性を低下させる。 When sprayed, Fe 2 O 3 quickly forms a uniform coating over a wide area. That is, it is a component that improves fluidity at heating temperatures, but if it is less than 5% by weight, the effect is poor, and if it exceeds 8% by weight, it reduces the heat resistance and corrosion resistance of the coating layer.
なお、SiO2、MgO、CaO、Al2O3、Fe2O3の外

ても本発明の溶射材の効果は殆ど変らない。 Furthermore, even if NiO, MnO 2 and Cr 2 O 3 in addition to SiO 2 , MgO, CaO, Al 2 O 3 and Fe 2 O 3 are contained in amounts of 1% by weight or less, the effect of the thermal spray material of the present invention hardly changes. do not have.

フリツトよりなる。(Function) The thermal spray material of the present invention contains various raw materials such as 50 to 54% by weight of SiO 2 , 30 to 40% by weight of MgO, 0.5 to 6% by weight of CaO,
A mixture containing 1.5 to 5% by weight of Al 2 O 3 and 5 to 8% by weight of Fe 2 O 3 is melted in a gas furnace or electric furnace, and then the molten metal is cooled with water to obtain a mixture. It consists of a frit made by crushing glass with a ball mill, etc.

Use products that have been crushed and classified to a certain degree.
This thermal spray material made of frit is sprayed by a plasma jet from a distance of 50 mm to 150 mm from the surface of the metal aluminum plate in an atmosphere at room temperature and atmospheric pressure.

のの落差は23cmであつた。2. In order to check the adhesion of the coating layer as well as the impact resistance, a steel ball with a diameter of 36.5 mm and a weight of 200 g was dropped onto the sample, and the drop when the coating layer peeled off was determined. The head of the one that did was 38
cm, and the height of the one coated with aluminum enamel was 23 cm.
