Galvanized Steel vs High Carbon Steel: Mechanical Performance

Click For Summary
Galvanized steel is often considered inferior in mechanical performance compared to high carbon steel, particularly in demanding applications. It is electrochemically reactive, leading to quicker degradation in certain environments, which limits its use as a replacement for high carbon steel. While zinc coatings provide some protection, alternatives like epoxy paint or powder coatings offer longer-lasting durability and less reactivity. Recent advancements in these coatings may enhance their protective qualities further. Understanding the specific project requirements is crucial for selecting the appropriate material.

TL;DR
In what condition and how galvanized steel is lower mechanical performant
In what condition and how definitively galvanized steel is lower in mechanical performance and counts to be ruled out replacing high carbon steel ?

That's pretty generic. Can you elaborate a little on your project, its needs and application?

You can galvanize high carbon steel.

Zinc coatings are employed where electrical conductivity is required, but galvanized steel is electrochemically reactive in the environment and will be consumed. Epoxy paint, or a powder coat, is not as reactive as zinc, and will now protect an item for longer than a sacrificial zinc coating.

Is this new (i.e are. there new improvements to powder coat and epoxe?) Do you have a handy reference?
 
https://newatlas.com/technology/abenics-versatile-active-ball-joint-gear/ They say this could be used as a shoulder joint for robots. Mind boggling! I'm amazed this has been done in real life. The model they show seems impractical to me. The ball spins in place but doesn't connect to anything. I guess what they would do would be attach a shaft to that ball, then restrict the motion so the drive gears don't contact the shaft. The ball would have two limited degrees of freedom then a...
