A coating, a coating system, and a coating method are provided. The coating includes between about 0.25-35% filler particles embedded in a chrome phosphate binder matrix comprising a balance of the coating by volume. The filler particles have a size in the range from nanosize to six microns with an aspect ratio of from 1:1 to 3:1, and include up to 100% by weight lubricious particles with a balance hard particles. The lubricious particles are selected from the group consisting of boron nitride (BN), titanium nitride (TiN), titanium oxide (TiO2), zinc (Zn), tin (Sn), oxides of zinc and tin, and combinations thereof. The hard particles are selected from the group consisting of chromium carbide (CrC), tungsten carbide (WC), silicon (Si), aluminum (Al), oxides or nitrides of silicon and aluminum, and combinations thereof. A green slurry coating includes an evaporable solvent mixed with the filler particles and chrome phosphate binder matrix.
