取り扱い方法を提供することを目的とする。 By the way, many structural ceramic parts have complex shapes and are heavy, and it is known that defects such as cracks can occur, especially in the corner ridges, when ceramic parts come into contact or collide with each other. There is. If the number of products produced is small, this problem can be avoided by carefully handling each product by hand, but as production scale increases and mechanization increases, defects due to contact and collision may occur. It becomes easier. For this reason, a method for handling ceramic parts suitable for mass production is desired.
In particular, from the inspection process until assembly, there is no means to eliminate defects that occur during this period, so a handling method that does not cause defects in ceramic parts is desired. [Object of the Invention] The present invention satisfies such needs. It was made based on
The purpose of the present invention is to provide a method for handling ceramic parts that enables mass transportation without causing defects in the ceramic parts in the process from manufacturing to assembly of structural ceramic parts.

According to the present invention, an object of the present invention is to provide a method for handling ceramic parts when transporting the ceramic parts to a working position for the next process in a process ranging from manufacturing to assembly, the method comprising: A protective film is formed on the crest, and then transported to a predetermined position.
This is achieved by a method of handling ceramic parts, which is characterized by subsequent heating.
本発明は成形、脱脂、焼成、加工、検査、組付

程で飛散させることができる。 When the protective film provided on ceramic parts is no longer needed, it is oxidized (burned) and disappears by heating it to 300 to 500°C. It should be noted that there is no particular need to provide a fuel process if the product is processed or used in a high temperature state during the next process, assembly, or use. For example, in the case of ceramic chamber parts, they will soften and be removed at the ring temperature during the shrink-fitting process, and if the ceramic chamber parts are assembled into the cylinder head as is, they will be removed at the temperature during actual machine operation. Scattered due to Furthermore, if the turbine wheel is manufactured from ceramic parts, the ceramic parts can be dispersed by exhaust gas after assembly. Furthermore, if the ceramic part is a molded body,
It can be dispersed in the next degreasing process,
If the ceramic part is a degreased body, it can be scattered in the next firing process.

In the present invention, since a protective film is formed on the ceramic parts, even if the ceramic parts come into contact with or collide with other objects during the process from molding to assembly, the impact at the time of the collision is protected. Since it is weakened by the film, the occurrence of cracks, etc. is greatly reduced.
