Influence of industrial cleaning fluids on anode-oxidative protective-decorative coating obtained in solutions of chrome anhydride
The subject of research in this article is the anode-oxide coating of aluminum parts of the hull type of aircraft engine units and aircraft units under the influence of cleaning fluids of different nature and chemical compositions. The purpose of this work is to experimentally test, the effect of di...
