基于火焰喷涂技术的高温涂层热电偶的超快制备及性能研究
A study on the ultra-rapid fabrication and performance of high-temperature coating thermocouples based on flame-spraying technology
摘要
Abstract
The accurate measurement of surface temperature of hot-end components of aero-engines is a crucial basis for their performance evaluation.In light of the structural characteristics of aero-engine blades,an ultra-rapid fabrication method based on flame-spraying technology was proposed for coating thermocouples.NiCr/NiSi-based coating thermocouples were deposited onto flat nickel-based alloy substrates,and their thermoelectric output properties were evaluated and calibrated under atmospheric flame conditions.The results indicate a linear relationship between the output voltage of the fabricated coating thermocouples and the temperature difference,with a Seebeck coefficient of 38.9 μV/K.The measurements show good repeatability over four cycles,with a minimum error as low as 0.13%.The coating thermocouples can operate stably up to 1 100℃and withstand temperatures as high as 1 150℃.The coatings also exhibit good adhesion at high temperatures.关键词
