摘要：

Scanning acoustic microscopy (SAM) has been applied to different commercial coating systems on steel substrates in order to evaluate the potential of the method for fast non-destructive testing during material development: the focus was on defect detection after and during accelerated weathering and corrosion tests. The possibility of detecting hidden defects (e.g., blisters) in an early stage of weathering or corrosion tests has been evaluated for different commercial coating systems. Using different scanning modes 2K polyurethane systems (solvent- and water-borne) have been examined by SAM. Debonding at the polymer/substrate interface and the interface between base coat and top coat has been studied in samples after simulated weathering. The time dependence of "blister nucleation and growth" has been studied during a salt spray test. Furthermore, the surface topography has been investigated for UV-cured acrylic systems with and without antioxidants after simulated weathering. (C) 2008 Elsevier B.V. All rights reserved.
