Slurry for micro-engine thrust chamber and preparation method and application of slurry
A thrust chamber and engine technology, which is applied to the slurry for the thrust chamber of a micro-small engine and its preparation and application fields, can solve the problem that the performance and life of the micro-small nozzle cannot meet the use requirements, the coating thickness is difficult, and the coating thickness is difficult. The coating on the throat of the nozzle is easy to accumulate and other problems, so as to achieve the effect of low cost, guaranteed coating thickness and high work efficiency.
