Fremgangsmåte til fremstilling av et beskyttende belegg og en motor med minst en komponent utstyrt med et beskyttende belegg

摘要

The invention relates to a method for producing a protective covering on the surface of components that are made of cast iron which serves as a base material. The protective covering consists of a comparatively soft outer layer (9) and of a wear-resistant support layer (8) which is significantly harder than said outer layer and which is located thereunder. The aim of the invention is to be able to easily produce a protective covering with a support layer (8) which has a comparatively high degree of hardness. To this end, at least one layer (7) which consists of an aluminum bronze and which forms the two-layer protective covering is melted onto the base material (6) consisting of cast iron.
