摘要

1. The Neutral NSS uncovers mainly coating defects 1.1 Defects of passivate & sealer: White corrosion 1.2 Defects of metal plating: Red corrosion 1.3 If passivate and sealer show no defects, several hundreds of hours in NSS can be achieved 2. CCT's do have different corrosion mechanism 2.1 Correlation to ASTM B117 difficultot possible 3. CCT's uncover coating defects and may base material defects. 4. CCT's do have multiple corrosion mechanism 4.1 Different attack though wet/dry phases 4.2 Thermo cycles 5. Can CCT's differentiate between finishes? 6. Can CCT's predict real life corrosion? 6.1 Correlation need to be determined at OEM level 7. CCT's will drive changes in the development of metal surface finishing.
