Abstract
Abstract A filler wire of a new type for use in arc spraying, by means of which coatings highly resistant to mechanical and/or chemical wear can be produced is provided. The wire comprises a soft sheath made from unalloyed or alloyed metal, inside which there is a very fine-grained filler material which contains, in addition to iron, other metals and/or special carbides and/or oxides, the powder being prepared by atomizing a melt of the said constituents.
