CO₂ Erosion of the Ni-TiN Nanocoatings Prepared by Electrodeposition

Abstract:

CO2 erosion; Ni-TiN nanocoating; electrodeposition Abstract. Ni-TiN nanocoatings were successfully fabricated by pluse electrodeposition (PED) on the surface of 20 steel. Microstructures of the coatings were investigated by XRD, SEM, and HRTEM. In the CO₂ erosion test, both 20 steel and Ni-TiN nanocoatings were evaluated using the autoclave. The XRD and HRTEM results demonstrated that the Ni-TiN nanocoatings were consisted of Ni phase and TiN phase. And the average diameter of Ni grains and TiN particles were approximately 52 nm and 30 nm, respectively. The CO₂ erosion experimental results indicated that the Ni-TiN nanocoatings showed better corrosion resistance than 20 steel. And CO₂ pressure had great effect on the erosion characteristic of Ni-TiN nanocoatings.
