Clad-metal interfaces and bond evaluation
The bond between metals is one part of a clad conductor specification. Evaluate the actual interface and formed product rather than assuming a universal bonding advantage.
Interface definition
Record the metals, layer thicknesses, material condition and manufacturing route. A bond description does not establish electrical performance, corrosion life or an operating-temperature limit.
Evidence for the product form
Use representative cross-sections and suitable bend, peel, tensile or other agreed methods for the actual geometry. Define specimen preparation, loading, units and acceptance before comparing results. A test suited to strip cannot automatically be assigned to round wire.
Process and service exposure
Assess changes after forming, joining, thermal cycling and the intended exposure. Delamination can have multiple contributing causes; correlate failure location with manufacturing records and test evidence before attributing it to cladding, coating or another process.
