I've noticed a lot of misinfo and hobby tier advice being bandied about here. Industry vet here. Need to plate plastics, glass or ceramics? Not sure if electroless Teflon Ni is right for you? Need to know how to set up tanks, heating, cooling, plumbing, rectifiers... Can't throw into that blind hole? Burning that high current density area? Need to know how to use thieves? Should I put hexavalent chromium on my cookware? What kind of waterway should I dump my spent chems in?
GO!

Anodic or cathodic cleaning, adhesion issues?
"Conversion" coatings like zincates and anodizing? Organic solderability preservatives?

Electro-polishing SS? Multi metal layers for decorative purposes like black Ni on Cu?

Immersion or hard electroplated Au?

Well, I'll be checking the thread.
Don't let those paint and powder-coat cunts slide this. Blasting their "ranchero" music all day.

I want to make an aviary. the most common material is galvanized hardware cloth. this contains zinc which, when a bird bites it can cause adverse health effects.

can your knowledge help me in any way?

Stainless steel mesh. Anything else would just be... not worth it.

Aside from the fucking music, any comments or criticisms of this setup:

I want to get some brush electroplating/polishing setup and atm I'm basing the equipment on this thing. Aside from the nuclear hazard it looks like a decent set up but what do I even know?

Really limited applications. A dip setup would be better, but you would need more chems.

The setup looks fine. An anode in a sponge, rectifier and solution.

I want to do some stuff very similar and in some cases the same as what they're doing in the vid, as well as plate some awkwardly shaped objects where getting a bath to fit them is more trouble than it's worth.

>>1633488
Good to know. Thanks to both of you.

Another question: electroplating plastics. What's a good conductive first layer? A lot of info I'm seeing out there is recommending fine graphite powder embedded into acrylic and sanding that down until shiny. What's the most robust method? I've got the idea into my head to make some of my automotive and machinery stuff look gaudy as hell and all shiny and chrome, weighing up options.

Electrolysis Ni is best on plastics. It's a pretty complicated process though, where you use silane to "etch" the plastic, then a palladium catalyst for the Ni. After that, you can do anything from chrome to Au

It sounds like it's decent for a lab scale process, I'll look into processes/papers and if the thread's still up get a follow up opinion or tips or whatever.

Can you use insulation fibre glass as a diaphragm for electrolysis?

Ever done electroless Ni for composites like carbon fiber?

no. It can probably be done, and probably involves silane
