I never heard of zinc anodes for boats, so I asked ChatGPT how they work: "Zinc anodes, also known as sacrificial anodes or zincs, are commonly used in boats and other marine structures to protect against corrosion. They work by utilizing a principle called galvanic corrosion, which involves sacrificing a more reactive metal to protect a less reactive one. Boats are typically made of materials such as steel, aluminum, or fiberglass, which are susceptible to corrosion when exposed to seawater. When a zinc anode is connected to the boat's metal hull or other metallic components, it becomes the most reactive metal in the system. When seawater comes into contact with the boat's hull and other metal parts, it acts as an electrolyte, creating an electrochemical cell. The zinc anode, being more reactive than the boat's metal, undergoes corrosion instead of the boat's metal. In this process, the zinc anode gradually corrodes and dissolves into the water. By sacrificing itself, the zinc anode prevents or minimizes corrosion on the boat's hull and other metal parts. This protects the boat's structural integrity and reduces the likelihood of costly damage caused by corrosion. It's important to regularly inspect and replace zinc anodes as needed, as they will eventually wear down and lose their effectiveness. The rate of corrosion depends on factors such as the water's salinity, the boat's location, and the amount of electrical current present in the environment. Overall, zinc anodes serve as a sacrificial barrier, safeguarding the boat's metal components by diverting corrosion away from them and onto the anode itself."
Hi PressTube, great video! As cathodic corrosion protection engineers, we wanted to share a tip: using old anodes and re-casting them into new ones might affect their metallic composition, which can impact their electrochemical efficiency. In other words, the anodes might not work as intendeed. Keep up the awesome work with your videos!
Love this. Very old school vide video from back in the day here. Glad to see u still on here man. I know youtube hasn't treated u right. But glad to see this style video again. Keep em coming.
@PressTube well man. Been watching for long time now. Hope to keep watching. I remember when they started screwing with the channel. Content and quality is to good to just seen gone.
Cool project!! Awesome job. Hope you made some money off it.. glad your back.. Is that scare from the steam explosion a while back? Looks good though. 🍻👍
Thanks Bill! The scare is from an alumimium explosion, I'll post the video sometime soon. Was very scary but being covered in safety equipment saved me
Hi, reallly i am amazed this video, can you pls tell me the furnace name? What type of furnace is used? Then What did you use when making that mold? I mean what raw material? sand or clay or something?
While the initiative to recycle and repurpose old anodes demonstrated in this video showcases an admirable effort toward sustainability, it's crucial to understand the implications from a cathodic protection specialist's perspective. As professionals in the field, we've observed that once anodes are consumed beyond 40-50%, their metal balance is significantly altered. Melting down and recasting these anodes without adjusting the metal composition according to stringent standards compromises their functionality and effectiveness in corrosion protection. This practice could inadvertently mislead those in the boating industry and boat owners into believing it's a viable method, potentially risking the integrity and safety of marine equipment. While we support innovative recycling methods, we strongly advise consulting with a corrosion professional before adopting such practices. It's essential to ensure that any recycled anodes meet the necessary specifications for effective cathodic protection. Let's strive for sustainability while upholding the highest standards of safety and performance.
Zinc anodes are not made with pure zinc but with a very exact alloy of aluminum and cadmium. If you recast the anodes, I assure you that this alloy will no longer be valid to guarantee the function as a sacrificial anode.
Sacrificial anodes, salt water eats metal which is bad for boats. But someone figured out that if you put these zinc anodes on the hull, they'll slow down any corrosion on the steel. That's why the ones he melted looked gnarly!

Yep, nailed it :)
I hope you were wearing a respirator for that. Zinc fumes are no joke, even when you're outside.
Either way, awesome work
Great point! I totally was!
I love your videos and I always will. I'm sorry that you got a burn. I hope you feel better soon!
Thank you so much!

I found one of these washed up on the beach and thought it was a alien mobile phone
hahaha, fair.

Thanks for seeing me Chad, you totally get it
@PressTube well man. Been watching for long time now. Hope to keep watching. I remember when they started screwing with the channel. Content and quality is to good to just seen gone.
Good to see you back :)
Thank you Funny Cobra! I am back for goooood :)
That is pretty cool mate, good job!
Thank you! Cheers!

@@PressTube 🙂👍
Ty for video again
Thank you for watching Walter!
I am a metal fan so ... I like this :D
Thank you Klaus! What else would you like to see next?
❤❤❤❤❤❤❤❤❤
Cool!
Thank you!
What purpose did the nuts you placed on top of the metal brackets serve?
To prevent the metal brackets from floating. The zinc is heavier then the brackets, and they could start floating on top of it :)
Hi, reallly i am amazed this video, can you pls tell me the furnace name? What type of furnace is used? Then What did you use when making that mold? I mean what raw material? sand or clay or something?
Stupid question but what is the orange stuff you use to make the mold?
Casting sand
What that is for ? it important for boat ? sorry i never know

You sound like a lot of fun!
if you're not sleeping in a grounded bed can you even anodize a boat?
lolll
100. like 👍
Thank you!

gute Kopien ob sie sich aber auch genauso abnutzen ?
If they do, we will find out soon :)
Do not breathe that.
First
indeed!
