Cladding Diffusion Barrier Interlayer
An interlayer in metal composites that prevents diffusion between the base material and the overlay and stabilizes the bond at high temperatures.
Physico-chemical mechanism of action
The plating diffusion barrier forms a barrier that prevents the exchange of atoms between the two metals. This is achieved by a chemical bond or strong physical contact that interrupts diffusion processes.
Metallurgical relevance & risks in welding
Without such a layer, long-term material wear and loss of properties can occur. This leads to a reduced service life of composite materials, especially at high operating temperatures or under chemical loads.
Workshop practice & instructions
When producing metal composites, it is crucial to apply the plating diffusion barrier correctly. This requires precisely controlled melting and cooling management as well as the use of suitable materials for the intermediate layer. The temperature and cooling time must be precisely controlled to create a stable diffusion barrier.
