本文主要阐述了用于航天发动机领域的铌基合金高温抗氧化涂层厚度不均匀性造成发动机喷管表面质量缺陷和性能下降,并就造成涂层厚度不均匀性以及由厚度不均匀性引起的表面质量缺陷和性能下降的原因进行简要的分析,最终提出几点预防措施和解决方法。
This article mainly expounds the non-uniform thickness of high-temperature anti-oxidation coating of niobium-based alloy used in the field of aerospace engine, which causes the defects of engine nozzle surface quality and the degradation of performance, and causes the nonuniformity of coating thickness and the nonuniformity of thickness Surface quality defects and performance degradation of the reasons for a brief analysis of the final proposed a few preventive measures and solutions.
