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 …

This chapter provides a comprehensive review of both inorganic and organic pretreatment
coatings for metals and alloys. Aqueous and nonaqueous corrosion are introduced as well …

The novel cerium based conversion (CeC) treatment was performed on 2A14-T3511
aluminum alloy micro-arc oxidation (MAO) coatings with thickness of 15 μm and 30 μm …

High-velocity oxy-fuel-sprayed FeCrMoMnWBCSi amorphous metallic coatings were sealed
with sodium orthosilicate (Na3SiO4), aluminium phosphate (AlPO4), and cerium salt …

Environmentally friendly Ce-based sealing post-treatments were developed for PEO
coatings on AM50 magnesium alloy. The influence of the Ce (NO 3) 3 concentration in the …

Abstract Ti-15-3 titanium alloy has been widely used as a connecting material for aerospace
structural parts. However, the non-uniform pitting caused by salt spray corrosion and the …

This study introduces the surface modification of the low carbon steel by an effective
corrosion protective composite film based on Nd-PAA-BI (neodymium-polyacrylic acid …

In this work, solutions containing lanthanum salts were used for a post‐treatment of sealing
to increase the corrosion resistance of PEO coated AZ91 alloy. PEO coatings were produced …

Zirconium conversion coatings prepared in a 200 ppm H 2 ZrF 6 bath for optimal conversion
times, were applied on aluminium alloys starting from AA1xxx up to AA7xxx series. The …

SiC particles are an important reinforced phase in metal matrix composites. Their effect on
the microarc oxidation (MAO, also named plasma electrolytic oxidation-PEO) process of SiC …
