Abstract

The process of application of coating on metal surfaces is described in this article. The composition with 100 % corrosion preventing substance + 42,5 % acetone + 10 % halloysite was recognized as the most appropriate for coating, and it provides the best corrosion resistance of hydraulic pump details. The impellers of circulation pumps for water delivery in heating system fail after 5 - 6 months because of the galling of work flutes, as water doesn’t pass through the chemical purification. After applying corrosion resistant coating with halloysite the lifetime of impellers increases. The essence of which is dipping the impeller into hydrochloric acid with 24 hour keeping in it, then it is dried in dryer up to 4 hours. The lifetime of this impeller increases 1,8 fold and it was approximately 9 months.
