Abstract
An anti-corrosive coating is formed on ferrous metal by immersing the metal first in a bath containing phosphoric acid and then in a bath of oil containing graphite in colloidal suspension. The metal may be treated in a bath containing 1/2 -1 per cent phosphoric acid, washed to remove all traces of acid, and then immersed in a colloidal suspension of graphite in oil, preferably linseed oil, the suspension containing 1 fluid ounce of graphite per gallon of oil. The graphite fills the pores in the metal and in conjunction with the phosphate coating protects the ferrous metal from corrosion. According to the Provisional Specification, colloidal suspensions of relatively inert solid substances other than graphite may be used.
