Protective coatings and methods of forming same

摘要

Coatings on a substrate and application methods result in coatings that can withstand different types or groups of bulk cargo and operations. This novel approach includes use of a combination of layers of coating materials at certain thicknesses and applied with certain techniques. In certain embodiments, the coating system includes coatings applied to a pretreated substrate, e.g., blasted steel cargo hold plates of an oceangoing vessel. The coatings include a bond layer and a resistance layer, e.g., an anti-corrosive layer tailored to resist at least one of corrosion, erosion, impact and wear of the substrate.

主权项

1. A multi-layer transportation vessel hold surface protective coating arranged in or on a transportation vessel, comprising:
a thermal sprayed bonding layer formed on and in contact with a first face of the transportation vessel hold surface prepared in a manner to allow the bonding layer to adhere, the bonding layer having a hold surface face and a non-hold surface face; a resistance layer made of a material resistant to impact forces and corrosion caused by a corrosive environment in a vicinity of the transportation vessel hold surface arranged in or on the transportation vessel, the resistance layer formed on and in contact with the non-substrate face of the bonding layer, the resistance layer having a bond face and a non-bond face; and a sealant layer formed on and in contact with the non-bond face of the resistance layer.
