Zinc coating is the best solution for protecting steel parts and tools from corrosion, especially if they are subject to friction. You can apply it yourself very cheaply and without difficulty.
Materials:
- zinc scrap;
- electrolyte for batteries;
- baking soda;
- alcohol;
- alkali.
Metal galvanizing process
Electrolyte is collected in a glass container and zinc scrap is added.
You can use old carburetor bodies.
When the zinc dissolves, which will take 20-30 minutes depending on the size of the pieces, the solution is filtered through cotton wool.
Alcohol is added to the filtered solution; for 400-500 ml, just take a cap from a PET bottle. After this, the metal is dipped into it for galvanizing.
After 10 minutes, the part is removed, rinsed in an aqueous solution of baking soda, then washed in water with alkali (Comet cleaning powder or an equivalent). You need to wash off the oxide with a metal dish scraper.
Next, the part is again dipped in the zinc solution for 15 minutes, then dipped in soda and washed with alkali and a scraper.
This procedure is repeated several times until the zinc forms a continuous layer.As a result, you can get a very high-quality, neat coating, just like a factory one. Using this method, it is possible to restore an old tool, protect bolts, nuts and other metal parts.
