摘要: 在涂渗与扩散两工序之间进行950℃/30min的预氧化处理可以大幅度提高ASL系列3型铝硅渗层的抗热腐蚀能力,而对渗层/基材系统的力学性能则无任何损害。分析证明,预氧化处理使这类铝-硅渗层的表面形成一层致密的,且铝、硅含量较高的氧化膜,其中二氧化硅的存在使氧化膜具有优越的抗热腐蚀性能。

Abstract：A simple preoxidizing treatment added between two processes of coat treatment and diffusion treatment increased considerably hot corrosion resistance of a series of ASL-3 type Al-Si coatings, but did not damage any mechanical properties of coating/substrate system. The analyses results indicated that the preoxidizing treatment led to the formation of a dense and thin Al-and Si-rieh oxide film on the surface of the coating. The presence of SiO_2 within the film accounted for the superior hot corrosion resistance of the coating.
