Abstract

1. Method for the manufacture of wear-resistant composite articles (1) from a metallic base material with a highly wear-resistant area (2) in which particles of hard material are incorporated within the base material, characterized in that the base material, in the form of at least one electrode (3, 33, 43), is continuously remelted by the electrode-slag remelting process in an arrangement of moulds (4 ; 23, 24) under a layer of liquid slag (9) forming a solidified ingot growing from the bottom of the mould arrangement, during which process a pool of molten metal (10 ; 28) forms under the slag layer, and that hard meterial particles (11) with a grain size of 0.1...20 mm are added to the pool (10) for at least one period of time for embedding in the base material, with the period of time or the sum of all time periods being shorter than the total electrode (3) remelting time.
