The present disclosure relates to agents, compositions, and methods for inhibiting corrosion in various substrates, for example in metal substrates. The present disclosure also relates to compositions for inhibiting corrosion comprising at least one organic heterocyclic compound and at least one metal salt or mixed metal salt selected from rare earth, alkali earth and transition metals.

Compositions for inhibiting corrosion

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.

Soluble corrosion resistant sol-gel

The present disclosure is directed to processes, compositions and agents for inhibiting corrosion in various substrates, for example metal substrates. The present disclosure is also directed to corrosion inhibitors comprising organometallic polymers such as metal-organic frameworks (MOFs), including compositions and processes comprising MOFs for inhibiting corrosion in metal substrates.

Polymeric agents and compositions for inhibiting corrosion

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&#xb0; 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.

Processes, compositions and agents are included for inhibiting corrosion in various substrates, for example metal substrates. Corrosion inhibitors include organometallic polymers such as metal-organic frameworks (MOFs), including compositions and processes comprising MOFs for inhibiting corrosion in metal substrates. In some aspects, a method of protecting a substrate from corrosion includes applying a protective composition including a corrosion inhibitor to the surface of a substrate, where the corrosion inhibitor includes a metal organic framework (MOF).
