Abstract
The invention concerns a composite material consisting of intermetallic phases and ceramic, in particular in the form of a coating on metallic substrates, as well as an arc wire spraying process for production of the composite material in which the intermetallic phases and the ceramics to be deposited are newly formed during the deposit process from the components of the supplied wires by chemical reaction. The invention further concerns wear resistant layers formed by the composites, tribologic layers and plating or hard-facing materials.
Claims22
A process for producing a composite material of metallic, intermetallic and ceramic phases by depositing it's components by means of arc wire spraying with at least one composite wire of metal or metal alloy and ceramic particles, wherein these undergo reactions during depositing forming intermetallic phases and new ceramic phases, wherein more than 70% of the ceramic particles undergo reactions during the spray processing with formation of intermetallic phases and new ceramic phases, and wherein the metal or the metal alloy, to the extent that it reacts, constitutes less than 10 vol. % of the formed composite material.
