If it’s not an electrochemical process, we can do parkerizing at home. Are most of the nuts and bolts that are “zinc phosphate” parkerized too? Maybe I need to start a new company to do this.
For small parts like nuts and bolts, you can just use a small glass with the solution and a microwave to heat it up to temperature.
This looks like an easier and better setup. Can get a couple of these so you can neutralize with simple green solution afterwards.
Sorry...didn't mean to send you down a rabbit hole! I agree that it looks like applying a phosphate coating at home could be done somewhat easily. With a little more effort and trial & error, it looks like you could plate components at home as well...Eastwood even sells a kit for it. https://garage.eastwood.com/eastwood-chatter/zinc-plate-at-home/
That is an awesome setup from Eastman. But that is actual zinc plating using electrochemistry with an electrolyte and electrodes. The hood hinges and other things that are zinc phosphate *coated* are not actually plated electrochemically from my new understanding. The zinc phosphate is a coating put on with a chemical process (chemical reactions but not electrochemistry with electrodes) commonly called parkerizing. The parkerizing chemical process is simpler in my opinion and we could do ourselves like that YouTube video. Maybe don’t use your wife’s cookware and glassware though . If you find a local gunsmith, you might be able to get them to do it. By the time you buy the chemicals, cookware, etc. unless you already have it or can find something at Goodwill or somewhere, probably costs about $100 in supplies for setup and will only take 20-30 minutes max for each part you want to put zinc phosphate on.
Zinc phosphate *coated* using a chemical *coating* process called parkerizing. They are not *plated* using electrochemistry.
