きるセラミック被覆層の形成方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a ceramic coating layer that covers the surface of mechanical elements that require wear resistance, corrosion resistance, etc., to maintain the performance of the mechanical elements and increase reliability. The present invention relates to a method for forming a ceramic coating layer that can reliably form a ceramic body at low cost.
［従来の技術］
近年、セラミックの利用は各種産業分野に広がり、それ

食性及び高硬度をもち且つ熱膨張係数が小さいことが挙
げられるが、金属に比して伸びが小さい欠点がある。Advantages of ceramics include wear resistance, corrosion resistance, high hardness, and a small coefficient of thermal expansion when compared to metals, but they have the disadvantage of low elongation compared to metals.
そこで、耐摩耗や耐食性を要求される金属表面にのみセ
ラミック被覆層を設ける技術開発が行なわれている。Therefore, technology is being developed to provide a ceramic coating layer only on metal surfaces that require wear resistance and corrosion resistance.
第６図に、セラミック材料を耐摩耗性材料として用いた
提案（実開昭６０−１７０００６号公報）を示す。FIG. 6 shows a proposal (Japanese Utility Model Application Publication No. 170006/1983) using a ceramic material as a wear-resistant material.
同図に示されるように、ａは吸気弁または排気弁を開閉

する側には、予めそのロッカ７−ムａの鋳造時にセラミ
ックチップＣを鋳込んである。As shown in the figure, a is a rocker arm that opens and closes an intake valve or an exhaust valve. A ceramic chip C is cast in advance on the side of the rocker arm a that contacts the cam b when the rocker 7-a is cast.
つまり、この提案では、カムｂと接する面にセラミック
チップＣを一体的に取り付けることによってロッカアー
ムａの摺動面の耐摩耗性を向上できるようにしている。That is, in this proposal, the wear resistance of the sliding surface of the rocker arm a can be improved by integrally attaching the ceramic chip C to the surface that contacts the cam b.
［発明が解決しようとする問題点コ

クスの１聞、慣性を考慮しなければならない。このため
上記提案では、セラミックチップにカムと接する面の反
対側にロッカアームに鋳ぐるみとなる脚を設・けて接合
強度を確保している。[Problems to be Solved by the Invention] In the above proposal, in order to integrate the ceramic chip into the rocker arm and form a single structure, the inertia of ceramics must be taken into consideration. For this reason, in the above proposal, a leg is provided on the opposite side of the ceramic chip from the surface in contact with the cam to serve as a cast-in part for the rocker arm to ensure joint strength.
しかし以下の問題を残している。However, the following problems remain.
■ 一体溝造であると当然ながらセラミックスの使用量
が多くなり、コストが上昇すると共にセラミックス使用
量のｊ台加に伴なって内部欠陥の確率が重加する。また
、一つの構造物として考えた場合、亀裂が発生しやすく
破損による機能不能を生じ易くなる。■ Naturally, if it is made of integral groove construction, the amount of ceramics used increases, which increases the cost and increases the probability of internal defects as the amount of ceramics used increases. Furthermore, when considered as a single structure, cracks are likely to occur, making it more likely that the structure will become inoperable due to damage.
■ 摺動される部品、摩耗される部品にとってｓｉｃを

ップの原因となる。■ For parts that slide or wear, ceramics other than SIC have low thermal conductivity and do not have good heat dissipation properties.If they are made into one structure as proposed above, the side to be joined In other words, in the above proposal, in order to cool the rocker arm, it is necessary to cool the ceramic chip with lubricating oil or to give the ceramic chip a shape that improves heat dissipation, which also increases costs. Cause.
■ セラミックスはヤング率が高いため、ヘルツ応力が
高く、接合される側の部材にとって好ましくない。■ Since ceramics have a high Young's modulus, they have a high Hertzian stress, which is undesirable for the members to be joined.
■ ロッカアーム等の接合される側の部材にセラミック

容易に対処できない。■ When ceramics are cast into the parts to be joined, such as a rocker arm, to form a single structure, the ceramics have a high degree of sophistication, making it difficult to handle finishing or reworking when needed.

るようにした技術が開発されている。The above proposal must satisfy various conditions in terms of manufacturing and cost. Therefore, in recent years, techniques have been developed in which sheet-shaped ceramic pieces are formed in advance and these pieces are pasted, techniques in which ceramics are coated by thermal spraying, and techniques in which ceramics are chemically vapor-deposited. being developed.
しかし、溶射及び蒸着による被覆技術は■被覆箇所以外

覆工程で必ず被覆の対象が必要であること、■被覆後の
後処理（研磨等）が困難であると共に都合によって被覆
層を剥離したい場合に、その剥離が困難であること等の
問題がある。However, coating techniques using thermal spraying and vapor deposition: ■ It is necessary to mask in some way other than the areas to be coated, ■ The target to be coated is always required in the coating process, and ■ Post-treatment (polishing, etc.) after coating is difficult. In addition, there is a problem in that when it is desired to peel off the coating layer for some reason, it is difficult to do so.

There are techniques to obtain ceramic pieces by firing.

Furthermore, the technique of stretching the ceramic base material thinly and firing it in advance requires a sintering aid, so there are problems in that the generation of pores cannot be easily eliminated, and there is also a fundamental problem in that it cannot be formed to a thickness of 100 μm or less.
