Abstract

La présente invention porte sur un procédé pour la fabrication d'une composition de céramique-plastique-céramique (CPC) devant être utilisée dans l'application d'un revêtement sur une surface métallique. Plus particulièrement, la présente invention comprend les étapes consistant à : préparer une poudre de coquillage; ajouter de la fine poudre céramique et de la poudre de polyéthylène modifié à la poudre de coquillage; pulvériser la poudre de coquillage, la fine poudre céramique et la poudre de polyéthylène modifié pour préparer de cette manière une composition ayant des propriétés améliorées; et appliquer sur la surface d'un tuyau en acier et de béton un revêtement de la composition à l'aide d'un procédé d'application de revêtement par projection à chaud. Selon la présente invention, des coquillages enterrés sous terre ou immergés dans la mer sont pulvérisés et de la poudre céramique et de la poudre de polyéthylène sont ensuite mélangées avec ceux-ci pour les utiliser avec un appareil d'application de revêtement par projection à chaud, ce qui de cette manière augmente l'efficacité de l'application du revêtement, recycle les coquillages pour empêcher une contamination environnementale et réduire les coûts d'évacuation des déchets et empêche un court-circuit de se produire sur une surface en fer dans la mesure où une application de revêtement à l'état fondu est possible sans se soucier d'une couche de corrosion qui est formée sur la surface en fer.
