This Application Note describes the preparation method
"Cross Sectioning of Ni/Cu on Steel"
Cross section of the coated steel to see the layers and interfaces.
Mechanical polishing of soft materials leads to smearing. The smeared material covers the sample surface and makes structural investigation impossible. Ion beam slope cutting is a method that can achieve a flat cut of material combinations consisting of hard and soft materials without smearing.
