Rare earths are among the most promising options for replacing chromate conversion
coatings on aluminium. In nearly three decades of research, several hundred papers have …

Anticorrosive protection of Al alloys still depends heavily on the use of chromates, which are
widely and universally employed as chromate conversion coating and chromic acid …

Cerium-based conversion coatings were deposited on aluminium alloy 6061-T6 by
immersion in two cerium salt sources (chloride-and nitrate-based) assisted with hydrogen …

An improved process has been developed for the spontaneous deposition of cerium oxide
conversion coatings for corrosion protection of aluminum alloy 7075-T6. Approximately 80 …

The steel samples were pre-treated by cerium conversion layer. Then, zinc phosphate
conversion coating was used as sealing agent for the cerium conversion layer to enhance its …

Cerium oxide solid samples were prepared via precipitation from aqueous solution of
hydrous cerium (III) nitrate in the presence of different percentages of hydrogen peroxide …

Aluminium nanoparticles were modified by cerium oxides/hydroxides in order to enhance
their corrosion resistance. Then, Ce-Al nanoparticles were functionalized with 3 …

Cerium-based conversion coatings were deposited on Rheo-High Pressure Die Cast
(HPDC) Al-Si alloys by immersion in cerium nitrate aqueous solutions. Rheocast Al-Si alloys …

The effect of alkaline cleaning and activation on the composition and thickness of the oxide
layer on aluminum alloy 7075-T6 was studied. E–pH diagrams were developed to predict …

The cerium-based conversion coatings on galvanized steel were investigated and the
influence of SO42− on the corrosion behavior was evaluated. The coatings were prepared …
