A multi-layer protective coating for a substrate arranged in or on a vessel and method of forming multi-layer protective coating on a substrate arranged in or on a vessel. Multi-layer protective coating includes a thermal sprayed bonding layer formed on and in contact with a first face of the substrate prepared in a manner to allow the bonding layer to adhere, the bonding layer having a substrate face and a non-substrate face, a resistance layer made of a material resistant to impact forces and corrosion caused by a corrosive environment in a vicinity of the substrate arranged in or on the 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.
