Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

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.

The present invention relates to a method of inhibiting corrosion of steel in contact with a corrosive solution. The method involves mixing an olive leaf extract titanium nanocomposite with the corrosive solution. The olive leaf extract titanium nanocomposite may be made by reducing TiCl.sub.4 with an olive leaf extract, which forms nanoparticles with an average size of 50-100 nm.

A corrosion inhibitor for a central heating system is provided in the form of a cream having low water content, which may be encapsulated within a water-soluble film, for example a poly (vinyl alcohol) film. The corrosion inhibitor product is more highly-concentrated than known liquid inhibitors, and the encapsulation in a water soluble film provides for safer handling and eliminates waste from plastic packaging.

An aqueous solution (20) is an aqueous solution used for repairing an aluminum-coated steel wire (10) with defects leading to there being iron, which contains magnesium chloride having a concentration of 10% or more, and magnesium sulfate having a concentration of 6% or more, and which allows an anticorrosion layer made of an alloy component of magnesium and aluminum to be formed.

A galvanized steel sheet is covered with an organic resin containing an anticorrosive additive that reduces galvanic current flowing between the zinc coating and the base steel sheet, to thereby considerably suppress intrusion of hydrogen into the steel sheet to prevent delayed fracture of the steel sheet.
