Good question. There are a few reasons. Initially cost - zinc and aluminium are a more cost-effective coating to apply compared to stainless steel. Different environments will determine whether you use zinc or aluminium (or indeed zinc/aluminium alloy). For example, most inland, relatively low corrosive environments you would use zinc. For more harsh environments close to the coast or in the sea, you would use aluminium or zinc/aluminium alloy. Zinc generally acts as a sacrificial coating to the steel substrate (remember the galvanic series). Aluminium primarily acts as a barrier coating. High-temperature applications, you would commonly use aluminium. In some very specific applications, you might use stainless or some high-temperature corrosion-resistant alloys like Inconel625 or HastelloyC276. Another consideration is that when you spray stainless steel, as you are melting the wire, some of the chrome burns off so you don't get exactly the same composition of stainless steel in the sprayed coating as you do on the raw material. But mainly, it's cost of zinc and aluminium that gives a suitable corrosion coating that gives more than 20 years life to first maintenance in the the most corrosive environments - there is no driver to use stainless steel. Just as an aside, stainless steel can still corrode in certain applications and environments and thermal spray aluminium is used as a protective coating onto duplex stainless pipes and structures.

Zinc and Aluminium is used most often in corrosion protection from that I see. Why stainless steel coating is not used?

Where can I get a machine like this in Ontario.
Hi Isaak, please contact our reseller in the US, TMS Metalizing. www.tmsmetalizing.com/. They'll be delighted to assist.
Hi. I'm looking for help with metal-spray on to aluminium (nickle preferably) Can anyone help with that?
+Karl Rusher Halo! What's your problem?
Been flame spraying for 50yrs,, last4lerry@gmail.com , think I can help you
Gas ratio
3-1 gas ratio ?
What is the powder that is used to spray aluminum ?
Just like MIG it is wire fed, on that system.
thank you for the video
I'm sorry to be that chap, I'm colour blind and couldn't see a great deal of your text.
Thanks for the feedback. I'm sorry but that is not something that we have considered. We will give it consideration for future videos.
