Cross Sectioning of Painted Concrete

Application Note for Leica EM TIC 3X - Industrial Manufacturing

October 10, 2016

Purpose
Ion beam slope cutting is a method that can achieve flat cuts of material combinations consisting of hard and soft materials.

Goal
Cross section to see the interface between paint and concrete.

Process Description
(benchmark values for this particular sample)
Mechanical pre-preparation with the Leica EM TXP using 9 µm diamond lapping foil at 2600 rpm.

Leica EM TIC 3X Parameters
Acceleration voltage6 kV
Gun current2.2 mA
Milling time6 h


Results

  • The cut is flat and clean.
  • Organic binders and inorganic pigments are visible.
  • The interface between paint and concrete is visible.
