The adhesion of several washcoats deposited on stainless steel microchannels was investigated by performing a mechanical test (drop test) after application‐oriented tests, temperature cycling, and water exposure. For this study alumina washcoats (γ‐Al 2 O 3 ) and washcoats of commercially available alumina‐based catalyst powders (Pt/Al 2 O 3 , Rh/Al 2 O 3 ) were used. The deposited washcoats showed very good adhesion not only for fresh samples but also after the application‐oriented tests.
