Abstract (en)
[origin: WO9408071A1] The invention concerns a method of protecting chromium-steel substrates against corrosion and erosion at temperatures up to about 500 C. A protective layer containing aluminium is formed on the substrate. The invention calls for this to be done by first depositing a metallic layer containing aluminium and then hardening or annealing at least the surface of the protective layer. The invention enables highly effective protection to be provided, using simple techniques, against corrosion and erosion, particularly for turbine blades, and in particular turbocompressor blades.
