ことができる。b. Prior Art As an accelerated corrosion test method, the salt spray test specified in JISZ2371 is typical and widely used, but this is an independent test. However, in recent years, with advances in rust prevention technology, it now takes over 1,000 hours for a single test to produce test results. Therefore, recently, cycle tests such as "salt spray" → "dry in air" → "wet" (tentative name salt spray cycle test) have been conducted. According to the cycle test, the objective can be achieved in approximately 1/2 or less of the test time compared to the conventional single test.

The water tank 18 has a heater 19 for adjusting the water temperature and a bubbling nozzle for humidification, and although not shown, it is also accompanied by a water supply device, a water level adjustment device, etc., and the humidification mechanism alone is quite complicated. . Furthermore, there is a hot air blower 29 for hot air drying, which is also one of the reasons for increasing the manufacturing cost.

It is a double tank consisting of an outer tank 34 and an outer tank 34, the tops of which are joined and closed. Water 35 at the bottom of the outer tank 34
A space is provided between the water surface and the bottom of the inner tank 33. A salt water spray tower 7 is installed in the center of the test chamber, and inside the tower there is a salt water reservoir 6 at the bottom, a shielding plate 6' having small holes at the top to prevent salt water from evaporating, and an air nozzle 7 in the middle of the tower. ' and a salt water nozzle 7''. The salt water nozzle 7'' is piped to the salt water reservoir 6 via a solenoid valve 38. Separately, there are distilled water 22 in the air saturator 21, and a foaming nozzle 24 and a heater 23 in the water. The saturated air discharged from the air saturator passes through a pressure regulating valve 26 and a solenoid valve 40, and is then piped to the air nozzle 7'. After passing through the pressure regulating valve 25', the compressed air coming out of the compressor 25 is split into two parts at a branch 25'', one side is connected to the foaming nozzle 24 of the air saturator 21, and the other side is connected to the air heater 37 and the solenoid valve 39. through the air nozzle 7'.

Perform the "wet (condensation)" cycle test in any combination order. Next, the operation will be explained with reference to FIG. The test tank consists of a main body 1 and a lid 3. The top and side walls of the lid 3 are made heat insulating. The structure in which the main body 1 consists of an inner and outer tank and water is poured into the bottom space has already been explained, but the temperature inside the test tank is as follows.
The water vapor generated from the water tank heated by the heater 36 heats and adjusts the inner tank from the outside.

方に落ち、遮閉板６′の小孔から塩水溜に戻る。 During the salt spray test period, the compressed air from the air compressor 25 is pressure-adjusted and reaches the foaming nozzle 24 in the air saturator 21, where it foams and rises in hot water heated by the temperature-controlled heater 23. The air becomes saturated. This saturated air exits the air saturator, passes through a pressure-regulated solenoid valve 40, and is injected from an air nozzle 7'. At this time, the electromagnetic valve 38 is open, and the salt water in the salt water reservoir 6 is sucked up by the action of the air nozzle injection, is injected from the salt water nozzle 7'', and further ascends the spray tower 7, forming a salt water mist from the top to the entire circumference. At this time, the larger mist particles within the tower hit the inner wall of the tower and fall downward, returning to the salt water reservoir through the small holes in the shielding plate 6'.

At the same time, the solenoid valve 39 is opened, and the compressed air from the air compressor 25 is pressure-adjusted, heated by the air heater 37, and ejected from the air nozzle 7', creating a dry atmosphere inside the test chamber.
Dry the specimen. Since compressed air has been dehumidified from atmospheric moisture, it can improve the effectiveness of drying conditions. In addition, the shielding plate 6' above the salt water reservoir is
It serves to suppress salt water evaporation during the drying period.

8 and 39 are closed and only the solenoid valve 40 is open.
The compressed air from the air compressor 25 is turned into saturated air by the air saturator 21, passes through the solenoid valve 40, and is ejected from the air nozzle 7' to bring the inside of the test chamber into a high humidity state. Here, if the temperature during the previous drying period is lower than the wet temperature, dew condensation will occur on the surface of the test piece 9, providing an effective accelerated corrosion condition.
以上、「塩水噴霧」、「乾燥」、「湿潤（結露）」の
サイクルを任意の順序で行なうことが出来る。 As described above, the cycles of "salt spray", "drying", and "wetting (condensation)" can be performed in any order.

Results equivalent to those obtained using a cycle tester were obtained.
