Abstract

A method for making a radiation absorbing material (RAM) coating may include providing an iron-silicon alloy powder, forming the iron-silicon alloy powder into flakes, and passivating the flakes. The method may further include selecting passivated flakes having a desired size, and combining the selected passivated flakes with a carrier to provide the RAM coating. The coating may be applied to a substrate to impart the radiation absorbing property thereto.
