PROTECTIVE ADHESIVE COATINGS BASED ON TITANIUM AND MOLYBDENUM OXIDES
In the process of this work there were carried out experimental researches on the study of titanium-containing coatings with the addition of nickel and molybdenum on carbon steel. Their physicochemical properties and the possibility of using them as a substitute for phosphate coatings have also been studied. It was found that the presence of ammonium paramolybdate in the working solution accelerates the formation of titanium-containing coatings, increases their protective ability, reduces porosity and provides better grip with the subsequent lacquer paint coatings. It was determined that the deposition of conversion coatings without titanium ions is possible, however, such coatings do not have a high protective ability, and their thickness greatly exceeds the thickness of coatings based on hexafluorotitanic acid.
