Abstract

Accurate measurement of the surface temperature of the hot-end components of aero-engines is of great importance for health monitoring and design of the engine. As a non-contact temperature measurement technology, the phosphorescence temperature sensing technology based on thermal quenching effect developed rapidly in recent years. It obtains real-time temperature information by measuring the decay time or intensity ratio of the phosphor on the surface of the high-temperature component. Aiming at the problem of the high temperature failure and shedding of the phosphorescent film, polymer derived ceramics (PDC) is used as the adhesion layer, whose thermal and mechanical properties can be easily controlled by doping, to improve the high-temperature oxidation resistance and adhesion of the phosphorescent film. The phosphor temperature sensing film with Y₂O₃:Eu³⁺ phosphor and perhydropolysilazane (PHPS) precursor ceramics as temperature sensing substances and high-temperature bonding layer respectively is made on alumina and nickel-based alloy substrates. The phosphorescence emission spectrum and 611nm/620nm phosphor intensity ratio were measured with the 407nm excitation laser. The results show that the phosphor film on the aluminum oxide insulating substrate has higher phosphorescence intensity and temperature sensitivity than phosphor film on the nickel-based alloy metal substrate, the phosphorescence intensity decreases with the increase of sintering temperature, and the phosphor film using PDC as the bonding layer has the characteristics of high temperature oxidation resistance and strong adhesion.
