Layered electroless composite coating with metallic and composite nip layers
A recently granted patent (Publication Number: US11970779B2) discloses an electroless composite coating designed to enhance the resistance of pipelines to chemical and mechanical degradation. The coating consists of a layered structure alternating between a metallic NiP layer and a composite NiP layer, with the composite layer containing dispersed particles made up of a blend of different-sized particles. The metallic NiP layer and composite NiP layer contain phosphorus in varying amounts, with the dispersed particles being boron carbide particles and/or silicon nanoparticles.
The patent also covers a method for producing the system described above, involving the deposition of metallic NiP and composite NiP layers on a substrate in an alternating fashion. The method includes repeating the deposition process multiple times to achieve the desired layered structure. Additionally, a thermal treatment step is included, where the system is heated to a specific temperature range after depositing at least the first layer. The coating system can be applied to pipelines to improve their resistance to chemical and mechanical degradation, making it a valuable innovation in the field of pipeline protection technology.
