when damping ratio and modulus ratio is constant, damping value of coating system is proportional to the ratio of thickness, and the influence of the thickness ratio on damping of coating system was more significant. Therefore, increasing the difference of thickness between coating and interface was the most effective way to improving the system damping properties.
