Embodiment 1
The structured testing is mainly that EAST lower hybrid wave slicer designs provide foundation, and the first wall components of limiter front end will use tungsten
Cooling structure, tungsten substrate nickel packet boron carbide coating cooling structure basic unit are as shown in Figure 1.This spraying tungsten substrate 101 be
Tungsten string, tungsten substrate 101 overall length 270mm, Fig. 2 are that tungsten string sprays forward and backward photo.201 coating thickness of nickel packet boron carbide coating, 100 μ
M, wherein nickel content 60%, be carbonized boron content 40%.Using plasma sprays, about 11000 degrees Celsius of flame temperature.
Test block is as shown in Figure 3.It has chosen as shown in Figure 21,2 positions and carries out heat fatigue test.
It obtains lower hybrid wave to protect limiter tungsten hot face temperature under 4m/s flow conditions being 248 by numerical computations
DEG C, and heat fatigue test maximum temperature need it is 100 DEG C higher than numerical computations, therefore heat fatigue test maximum temperature determine exist
400℃.1 temperature of test surfaces changes in room temperature ~ 434 DEG C, 5.25 MW/m of heat flow density2, single thermal cycle times are 31s；It surveys
2 temperature of face of taking temperature changes at 100 ~ 416 DEG C, 6.94 MW/m of heat flow density2, single thermal cycle times are 53s.Two test tables
Face is different in temperature, surface thermal power and thermal cycle times etc., and reason is the tungsten string that manufacturer provides
Welding quality is different everywhere, affects heat transfer property everywhere.Fig. 4 is the thermal cycling temperature of test surfaces 1 and 2, is recycled altogether
1000 times.After 1000 cycles, two test surfaces do not observe that boron carbide coating falls off or other abnormal conditions, sees
Heat fatigue shown in Fig. 5 tests the photo on latter two surface, and it is not small to show that the tungsten string structure of the design can bear stable state thermic load
