Piece i.e. steel wearing plate, surfacing method for e.g. material crushing installation, involves depositing ceramic particles on part of surface of piece using distribution element whose outlet is disposed near end of deposit element

摘要

The method involves depositing agglomerate ceramic particles (4) on a part of a surface (1a) of a piece i.e. steel wearing plate (1), during a fusion operation, using a distribution element (5) having an outlet (5a). The outlet is disposed near an end (3a) of a deposit element (3) e.g. cored filler wire, in such a manner that a coating layer (2) is formed by a composite material comprising metal alloy e.g. iron and non-ferrous alloy, and the ceramic particles, where the ceramic particles are selected from alumina, zirconia, silica and a mixture of alumina and zirconia.
