Metal Deposition

Could be Hard chrome, or some propriatery coating like NICASIL. Also could just be surface hardening. Color difference can be misleading. What kind of equipment was it on?

Not much to go on.

It might have been joined by:

Explosive Welding - Explosive Bonded Metals - Explosive Metal Welding

Agreed, not much to go on. Scale? Is the piece shown 3/8" thick or 1-1/2"?

Sizes of samples? What comes to my mind is hardfacing, but that is just a shot in the dark. Agree as well, explosive welding or friction welding are also possibilities.

[edit] Looking at the pix again, I doubt that hardfacing would be that thick. The irregular surface would support that technique, but that is a lot of spray deposition.

its a half inch thick piece.

I did some googling and quite sure that it is a metal deposition using laser. Still want to confirm it. I was wondering what kind of metal is deposited which is so hard and even difficult to cut with torch.

It is a barrier of safe. Our marketing person gave it to us to study.

Good bye.

"marketing person" or people don't have a heart, or a conscience.

It is probably from a class TRTL-30 or -60 safe.

Construction of such equipment is, by their very nature, sort of a secret.

What are you studying it for? Are you trying to RE a competitor?

Yep. Its a sort of benchmarking. Trying to know what the competitor has done and do something better than them.

I dont think its TRTL 30 or 60. A 1/2" thick plate cannot give so much resistance.

it could be metal cladding with weld overlay, but I'm not sure.

If it's part of a commercial product, it's likely a lower cost process. I would guess plasma spray. I would have a chemical analysis performed of the substrate and the cladding. Knowing the chemical composition of the two will aid in figuring out the deposition method. I'm guessing that the cladding is a high cobalt material.

Agree with that, possibly flame spray stellite or similar.
