Estimating the term…
The invention provides metal members having liquid-repellent and corrosion-resistant surfaces, without the need for SAM surface treatment. A metal member of the disclosure has a porous surface, having the porous surface directly covered by a hydrocarbon-based oil comprising zinc dialkyldithiophosphate (ZnDTP). The porous surface may be an oxidized surface, and especially an anodized surface. The metal member may be a member of Al, Ti, Fe or Mg, or an alloy of any of these metals, or stainless steel. The concentration of the zinc dialkyldithiophosphate (ZnDTP) may be 0.1 mass % to 30.0 mass % with respect to the hydrocarbon-based oil.
A metal member having a porous surface, wherein the porous surface is directly covered by a hydrocarbon-based oil comprising zinc dialkyldithiophosphate (ZnDTP).
