Plates of molybdenum or molybdenum-based alloys can be manufactured by conventional powder metallurgy methods. Further, the shape of the tray may be any shape as long as the material to be heated can be placed on it; for example, the shape of the tray is medium! It may be a F-plate or a box-shaped one.

It is not necessary to form it on the entire surface of the base material, and it is sufficient to form it only on at least the portion that comes into contact with other trays or other articles during use.
コーティング層は大別してモリブデンに富んだ下地層と
実質的に耐熱性セラミックスからなる表面層からなる。The coating layer can be broadly divided into a molybdenum-rich base layer and a surface layer consisting essentially of heat-resistant ceramics.

性セラミックスを使用することができる。There is no need to clearly demarcate the straw top layer and the surface layer; ideally, the lowest layer, that is, the part that connects to the base material, is pure molybdenum (or molybdenum base metal), and the surface layer is made of heat-resistant ceramics. It is desirable that there is a concentration gradient such that the concentration of the oxide becomes higher, and that the uppermost layer is substantially a layer of heat-resistant ceramics. 1 for heat-resistant ceramics
For example, oxides such as alumina, magnesia, and zirconia are most suitable for N, but other known heat-resistant ceramics such as nitrides and borides can also be used.

＋ａＯＯ℃に加熱して焼成を行なう。Such a coating layer can be formed by, for example, plasma spraying, using molybdenum powder with an average particle size of about 3 to 5 microns, for example.
In order to improve fluidity, for example, a polyvinyl-based granulating agent is used to reduce the particle diameter to about 10 to 100 microns, more preferably 30 microns.
It is used by granulating it into spherical granules of about 80 microns. Furthermore, heat-resistant ceramics (for example) in the form of particles of about 0 to 40 microns are used. All you have to do is put the ζ straw into a commercially available plasma spray machine and spray it onto the surface of the substrate while adjusting the blending ratio of both. In order to improve adhesion, the surface of the plate is preferably roughened to a surface roughness of 30 to 60 microns. Once the desired coding layer has been formed by plasma spraying, it can be coated with 1,500 to 1,500 ml of coating material, for example in a hydrogen stream or in a small active atmosphere, to achieve a 1,500 ml density coating.
Firing is performed by heating to +aOO°C.

The same applies below) and a covering layer consisting of a mixture of 50% alumina.
Only layers are formed. Example 2 has a roughly two-layer structure in which a base layer of 100% molybdenum is first formed on the surface of the base material, and then a composite layer of 50% molybdenum and 50% alumina is formed. In addition, in Example 3, first a base layer of 100% molybdenum was formed, and then a base layer of 5% molybdenum was formed.
After forming a composite layer of 0% alumina and 50% alumina, a surface layer of 100% alumina was further formed on top of that. This structure can be schematically represented as shown in FIG. In the figure, A is the molybdenum base material, B is the coating layer, and B is the molybdenum base material.
1 is a pure molybdenum base layer, B2 is a composite layer of molybdenum and alumina, and B3 is a pure alumina surface layer. The thickness of the coating layer formed by plasma spraying was 10 to 1.50 microns. Among them, molybdenum 1. of Example 2.3.
The thickness of the 00% underlayer was 10-50 microns, preferably 30-50 microns. Firing temperature is 1500~
The temperature was 1800℃, the atmosphere was a hydrogen stream, and the holding time was 3
It was ~5 hours. Table 1 also shows a comparative example in which only an alumina layer was formed on the surface of the base material to a thickness of 200 microns.

象は生じなかった。The results of examining the peel strength of the coating layer for each of the above Examples and Comparative Examples are shown in Table 1. This peel strength was determined by bonding a steel material to the surface of the coating layer with an adhesive, applying a tensile load, and examining the load at which the coding layer peeled off. As can be seen from the table, the strength of the examples was 4 to 5 times greater than that of the comparative examples, and they were sufficiently durable for long-term use. Furthermore, when molybdenum trays having the structures of these Examples were actually used for sintering raw-F reactor fuel, no problematic adhesion phenomenon occurred in any of them.
