Deposition methods, protective coatings dipping

Another possibility of ceramic material application is the use of coatings and foams inside, for example, metallic microstructure devices. Here, well-known technologies such as CVD processes, sputtering, electrophoretic deposition, sol-gel methods in combination with spin coating, dip coating, or wash coating methods, or the use of anodic oxidation for aluminum-based devices will lead to either dense, protective ceramic coatings or porous layers used as catalyst support. 

Fabricating microlenses with a dipping method. (1) Fluoropolymer thin film is deposited on the surface by dip coating. (2) In areas not protected with a photomask, polymer is decomposed by low wavelength UV radiation. (3) Polymer solution is transferred onto hydrophilic spots using a needle printer. (4) After evaporation of solvent, the polymer is cross linked in a UV flood exposure. Source Dorrer, C., O. Prucker, and J. Riihe. 2007. Advanced Materials, 19(3), 456. With permission.)...
