Cladding Interface Diffusion Layer
Cladding interface diffusion is the atomic penetration of alloying elements at the bond line between base material and cladding during thermal processes. It significantly influences bond strength.
Physicochemical Mechanism of Action
Plating interlayer diffusion is a diffusion process where atoms of alloying elements from the plating diffuse into the base material. This process occurs during thermal processing steps such as welding or painting and is influenced by temperature and time.
Metallurgical Relevance & Risks in Welding
Plating interlayer diffusion can have both positive and negative effects. Positive effects include improved bond strength through a homogeneous connection between base material and plating. However, negative effects can lead to deterioration of mechanical properties if too many atoms diffuse from the plating into the base material. This can cause a changed chemical composition and possibly cracks or deformation.
Workshop Practice & Action Instructions
To optimize plating interlayer diffusion, it is important to carefully control welding temperature and time. Too high a temperature or too long a time can lead to over-diffusion of alloying elements. It is recommended to follow the specific technical data of the base material and plating used and adhere to corresponding welding parameters.
