Description

United States Patent COATING FOR METALS Arthur H. Happe, Detroit, Mich., assignor of one-half to Herman A. Sperlich, Detroit, Mich.
No Drawing. Application December 8, 1951, Serial No. 260,765
3 Claims. (Cl. 117127) The present invention relates to the g tinggi metals to pmtectmthem against corrosion under the in uen'ceTf moist or dry heat, aiidtoma-ke them resistant to chemical action and to errosion.
'Tr'ifiithEBbiteem of the invention is to provide a coating applicable to steels, aluminum, and other metals now used and proposed to be used for the construction of engine parts, plane parts, and other articles.
Another object is to provide a coating which shall have good adherence under severe conditions such as violent temperature changes, distortion, high temperatures, etc.
Another object is to provide a coating which may be applied as a thin coating and therefore less subject to chipping.
With these and other objects readily occurring to those skilled in the art, the invention consists broadly in the application by dipping, spraying or otherwise to the metal object a mixture of silicates'and metallic oxides in a water v ehicle, allowing to d ry andthen baking at a relatively low temperature.
a high sodium content 50 Metal oxides- Exfoiated vermiculite 10 Kaoln 10 The metal oxides are preferably about equal parts of nickel and cobalt OXides but good results have been obtained using titaniu'nf'or chromium for part or all of the nickel and cobalt oxide.
CROSS REFERENCE These materials are thoroughly mixed and ground together in a suitable mill and the result applied to the thoroughly cleaned metal. After drying, the coated metal is placed in a suitable oven and brought to a minimum temperature of 750 to 800 F.
The above proportions admit of some variation without material detriment. For example, the percentage of each of the metallic oxides may be varied to from 12-17% with a corresponding change of the other from 17l2% while the amounts of exfoliated vermiculite and kaolin may be increased or decreased one or two per cent. The exfoliated vermiculite is preferably the product found on the market under the trade name of Zonolite.
In the use of the coating, it has been successfully applied to steels, surface treated steels, enameling iron, aluminum, magnesium, magnesium alloys, titanium, molybdenum, and alloys of the latter two.
I claim:
1. A coating composition for metals consisting of L290 sp. gr. water sol li pnpflsodium silicate having a high sodium contentlf Cobaltoxide. 15% by weight Nickel oxide 15% by weight Exfoliated vermiculite 10% by Weight Kaolin 10% by weight 2. A coating composition for metals consisting of 1.290 sp. gr. water solution of sodium silicate having a high sodium content by weight obalt oxide 12-17% by weight Nic el 0X1 17-12% by weight Exfoliated vermiculitea 10% by weight Kaolin J Lie-Q21? 10% by weight 3. The process of coating metals which consists in applying thereto a thin layer of an intimate mixture of 1.290 sp. gr. water solution of sodium silicate having a high sodium content 50% by weight Cobalt oxide 15% by weight Nickel oxide 15% by weight Exfoliated vermiculite 10% by weight Kaolin 10% by weight and heating to a temperature of at least 750-800 F.
