Cr-based metal foil has high heat resistance and is unlikely to break due to oxidation in the air, but when used in cookers, heaters, electric furnaces, etc., salt from food and heated objects may adhere to it. When exposed to high temperatures, corrosion due to molten salts progresses, resulting in increased resistance and wire breakage.

照）。In Fig. 1, 1 is Fe-Cr-Alj metal foil (1
0x0.05x3000ff) and Tic on its surface.
The first coating layer 2 was formed by thermal spraying to a thickness of 50 μm, and the surface of the first coating layer 2 was coated with 90 parts by weight of polyborosiloxane, iron (Fe), manganese (Mn), and copper (Cu). 20 parts by weight of composite oxide, 218 parts by weight of ZrO, 4 parts by weight of aluminum oxide (Al2O2), 14 parts by weight
0 parts by weight, 60 parts by weight of toluene, and 60 parts by weight of xylene were mixed, spray-coated with paint, dried at 100°C for 30 minutes, baked at 400°C for 30 minutes, and at eoo'c for 30 minutes.
A heater wire was produced by forming the second coating layer 3, and the same as in the conventional example (the heater element was attached to an insulating substrate). When 20 wr of a saline solution with a concentration of 6% was dropped onto the surface of the heating element at 6 minute intervals while applying current (100 (V) 12 GA) to the heater element, the second coating layer peeled off even after repeating the process 15 times. There was no change in resistance value, and the change in resistance value was 7.
7.8Q for 5Ω, resistance increase rate is 4.0%
The voltage remained constant, and there was no disconnection (as shown in the fourth row of Table 1).

どは起こらなかった。Furthermore, in place of Tic of the first coating layer 2, 5 of Table 1 is added.
The various coating layers shown in the following rows are formed, and the same second coating layer 3 as described above is formed on the surface of the coating layer to produce a heater wire, and even if the same saline solution dropping test as described above is performed, no resistance is observed. The rate of increase in value remained at 4.0%, and no wire breakage or peeling of the coating layer occurred.

The layer peeled off and the wire broke.
捷た第１の被膜層のみで同様の試験をしたところ、被膜
