Abstract

The results of impedance tests of the agricultural sprayer bar frame protective coating by thermoplastic powder paints under production conditions, which confirm high quality and durability of the coating, are given. However, due to mechanical damages, penetration of liquid working environments or chemical fracture, the through defects can be formed in the coating. Thus, the access of water, oxygen and corrosive ions to the metal surface is significantly facilitated. At the place of damage local corrosion develops, and the coating barrier properties deteriorate.
