A method for coating a substrate, in which a wire-like the spraying material melted in an arc and as a layer is deposited on the substrate as well as wire the spraying material for electric arc spraying and wire arc-sprayed layer

摘要

A method for coating a substrate (1),in the case of a wire-like the spraying material (4) in an arc (5) is melted and as a layer (2) on the substrate (1) is deposited,in such a way that in the layer (2), after the deposition of martensite during solidification, bainite and pearlite are,a the spraying material is used,the substantially iron comprises,wherein the the spraying material (4) at least with carbon as the microalloy contains is formed in such a manner that, during the solidification of the spraying material are formed martensite, bainite and perlite,wherein, in the microalloy contains comprise solid lubricant portions or alloy components are provided for the formation of solid lubricant portions,characterized in thatthat in the used the spraying material contain the following alloy constituents are:– Carbon: 0.1% by weight to 0.28%.-%,– Manganese: 1.4% by weight to 2.1%.-%,– Silicon: 0.05 wt.% to 0.3 wt..-%,– Copper: 0.05% by weight to 0.25% by.-%in each case based on a total weight.
