Title
(EN) A NOVEL COATING CONCEPT
(FR) NOUVEAU CONCEPT DE REVÊTEMENT
Abstract
(EN)
The present invention relates to composition comprising a blend of at least one boron source and at least one silicon source, and the composition further comprises particles selected from particles having wear resistance properties, particles having surface enhancing properties, particles having catalytic properties or combinations thereof, wherein the blend comprises boron and silicon in a weight ratio boron to silicon within a range from about 3:100 wt:wt to about 100:3 wt:wt, wherein silicon and boron are present in the blend in at least 25 wt%, and wherein the at least one boron source and the at least one silicon source are oxygen free except for inevitable amounts of contaminating oxygen, and wherein the blend is a mechanical blend of particles in and the particles have an average particle size less than 250 µm. The present invention relates further to a method for providing a coated product and a coated product obtained by the method.
(FR)
La présente invention porte sur une composition comprenant un mélange d'au moins une source de bore et d'au moins une source de silicium, la composition comprenant en outre des particules choisies parmi des particules ayant des propriétés de résistance à l'usure, des particules ayant des propriétés d'amélioration de surface, des particules ayant des propriétés catalytiques ou des combinaisons de celles-ci, le mélange comprenant du bore et du silicium en un rapport pondéral du bore au silicium dans une plage d'environ 3:100 p:p à environ 100:3 p:p, le silicium et le bore étant présents dans le mélange à hauteur d'au moins 25 % en poids et ladite ou lesdites sources de bore et ladite ou lesdites sources de silicium étant exemptes d'oxygène sauf pour les quantités inévitables d'oxygène contaminant, le mélange étant un mélange mécanique de particules et les particules ayant une taille moyenne de particule inférieure à 250 µm. La présente invention porte en outre sur un procédé permettant d'obtenir un produit revêtu et sur un produit revêtu obtenu par le procédé.
