Abstract: The present disclosure provides a coated iron particle, or reaction product of a coating and the iron particle, comprising an iron particle and a ceramic coating disposed on the iron particle. Aspects of the present disclosure provide a coated iron particle, or reaction product of a coating and the iron particle, including an iron particle having a diameter of from about 0.5 micron to about 100 microns; and a ceramic coating disposed on the iron particle. Aspects of the present disclosure further provide compositions comprising a coated iron particle and a polymer or adhesion promoter. Aspects of the present disclosure further provide components, such as components, such as vehicle components, having a surface and a composition of the present disclosure disposed on the surface.

Abstract: Aspects described herein generally relate to a sol-gel that is the reaction product of an organosilane, a metal alkoxide, an acid, and chromium (III) salt and/or a lanthanide salt having a solubility of about 1 gram or greater per gram of sol-gel at 23° C. The lanthanide salt includes a cation and a ligand. The cation can be lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium, cobalt, calcium, strontium, barium, and zirconium. A ligand can be a nitrate, a trifluoromethane sulfonate, a sulfate, a phosphate, a hydroxide, or hydrate forms thereof. The chromium (III) salt includes a cation and a ligand. The cation is chromium (III) and the ligand can be a nitrate, a trifluoromethane sulfonate, a sulfate, a phosphate, a hydroxide, or hydrate forms thereof.

Abstract: Aspects described herein generally relate to a sol-gel that is the reaction product of a hydroxy organosilane, a metal alkoxide, an acid stabilizer, and a corrosion inhibitor. The hydroxy organosilane is represented by Formula (I): wherein R is selected from alkyl, cycloalkyl, ether, and aryl. The acid stabilizer is at a molar ratio of acid stabilizer to metal alkoxide of 1:1 or greater and the sol-gel has a pH from about 3 to about 4.

Abstract: Compositions are described for protecting a metal surface against corrosion. The composition includes a corrosion-inhibiting particle. The corrosion inhibiting particle may be usable in an epoxy resin-based coating or an olefin resin-based coating. The particle may include a core and a protectant. The core may include a water soluble corrosion inhibitor. The protectant may be disposed on at least a portion of a surface of the core and may be covalently or ionically bonded to a thiol group of the corrosion inhibitor. The protectant may be configured to reduce reaction between the core and the epoxy resin or the olefin resin. Methods of making the compositions are also disclosed.

Abstract: Aspects described herein generally relate to a sol-gel that is the reaction product of an organosilane, a metal alkoxide, an acid, and a thio-lanthanide salt having a solubility of about 1 gram or greater per gram of sol-gel at 23° C. The thio-lanthanide salt includes a cation and a thio-ligand. The cation can be lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium, cobalt, calcium, strontium, barium, and zirconium. In another aspect, a component, such as a vehicle component, includes a metal substrate and a sol-gel disposed on the metal substrate. Methods can include forming a sol-gel by mixing a metal alkoxide and an acid to form a first mixture; mixing with the first mixture an organosilane to form a second mixture; and mixing with the second mixture a lanthanide salt to form a third mixture.
