Abstract:
Temperature sensor of thermocouple prepared by the original process method often encounter fracture, which can't meet the demand of LOX/kerosene engine hot test and flight at higher working condition and longer working time.Considering the reliability of the sensor, a new pouring process based on frosting was ascertained from the aspects of selection of 8-2 frosting and alkali-free glass fiber sleeve, sintering process.And then reasonable process parameters were obtained.The sensor produced by the new pouring process does't have big air bubble, and examined by hot test of 1 950 seconds, resolves the fracture problem of the thermocouple.With new pouring material, pouring technology and sintering technology, this type of sensor has the advantages of reliable working in the strong vibration condition.
