Title
(EN) CAST STRUCTURAL ELEMENT OF A POMP, FILTER OR COMPRESSOR WITH WEAR RESISTANT LAYER COMPRISING COMPOSITE MATERIAL BASED ON ALLOYS REINFORCED WITH TUNGSTEN CARBIDE AND THE METHOD OF PRODUCING THEREOF
(FR) ÉLÉMENT STRUCTURAL COULÉ DE POMPE, DE FILTRE OU DE COMPRESSEUR POURVU D'UNE COUCHE RÉSISTANTE À L'USURE COMPRENANT UN MATÉRIAU COMPOSITE À BASE D'ALLIAGES RENFORCÉS PAR DU CARBURE DE TUNGSTÈNE ET SON PROCÉDÉ DE PRODUCTION
Abstract
(EN)
The invention is related to the cast structural element of a pump, filter or compressor with wear resistant layer comprising in situ produced composite material based on alloys, especially cast iron base alloys, reinforced with tungsten carbide in the form of crystals and / or particles, that can be characterized by the fact that the microstructure of the composite material within the layer comprising faceted crystals (6) and / or faceted particles tungsten carbide that provide uniform macroscopic and microscopic distribution, wherein the crystals (6) and / or particles of tungsten carbide include irregular and / or round and / or oval nano and or / micro-areas (7) filled with alloy based on metal. According to another aspect, the invention is related to the method of producing the cast structural element in the form of a pump, filter or compressor.
(FR)
L'invention concerne un élément structural coulé d'une pompe, d'un filtre ou d'un compresseur pourvu d'une couche résistante à l'usure comprenant un matériau composite produit in situ à base d'alliages, en particulier des alliages à base de fonte, renforcés par du carbure de tungstène sous forme de cristaux et/ou de particules, pouvant se caractériser en ce que la microstructure du matériau composite à l'intérieur de la couche comprend des cristaux (6) à facettes et/ou des particules à facettes de carbure de tungstène qui procurent une distribution macroscopique et microscopique uniforme, les cristaux (6) et/ou les particules de carbure de tungstène comprenant des nanorégions et/ou des microrégions irrégulières et/ou rondes et/ou ovales (7) remplies d'un alliage à base de métal. Dans un autre aspect, l'invention concerne le procédé de production de l'élément structural coulé sous la forme d'une pompe, d'un filtre ou d'un compresseur.
