Flake corrosion
WebZinc flake coating is used, above all, to reliably protect high-tensile steels, aluminum alloys and die-cast zinc against corrosion. When opting for this non-electrolytic coating solution, the risk of hydrogen embrittlement in the base material is minimized. Originally designed as a chromium VI-free alternative to electroplating, zinc flake ... WebSpherical zinc is well known as an effective pigment for the corrosion protection of carbon steel. However, a high proportion of spherical Zn in a coating leads to difficulties in fabricating the coating solution and increased cost. In this work, the influence of flake ZnAl alloy in silicate coatings on the corrosion protection properties of steel substrates was …
