Bonding of Metal

The bicycling industry has been bonding dissimilar metals for more than two decades.
In the the 80's and 90's, extruded aluminum was bonded to cast or forged aluminum components.
And, aluminum was also joined to steel frame/sub-frame components.

For the most part, the bonding agent was a high strength, engineering grade epoxy.

Izhmash is probably using a proprietary aerospace formula adopted from the struggling aviation and space industries - cross-over technology.

If heat is applied to remove the barrel, the damaged phosphate coating would need to be restored/refinished.
There are some metal finishing business specializing in military firearms that are capable of re-phosphating a firearm.

It would be interesting to find out how Mr. Sheppard is joining the separated receiver with its new barrel.
