A rust inhibiting process for cleaning and protecting a target object is disclosed. Comprising mixing at least a rust inhibitor and a fluid into a slurry mixture, spraying the slurry mixture at the target object from within a reservoir of a slurry blasting system, separating a tarnished top layer and a parent metal of the target object with a slurry stream, cleaning the parent metal with the rust inhibitor, preventing the parent metal from impregnating with contaminants during cleaning with the rust inhibitor, and protecting the parent metal with the rust inhibitor after spraying is complete. The slurry stream comprises the slurry mixture of the slurry blasting system being sprayed with the slurry blasting system. The slurry blasting system comprises a tank.

Corrosion inhibitors and methods for reducing or inhibiting corrosion of metals in aqueous systems are provided. Corrosion inhibitor compositions may include tetracarboxylic acids, such as butane tetracarboxylic acid. The compositions may include other components, such as zinc, molybdate, silicate, cerium, among others. The compositions may also include polymers or oligomers. The corrosion inhibitor compositions produced synergistic results and unexpectedly low corrosion rates.

The present invention relates to a method for increasing adhesion strength between a surface of copper or copper alloy and an organic layer, the method comprising in this order the steps: (i) providing a non-conductive substrate comprising on at least one side said surface, said surface having a total surface area of copper or copper alloy, (ii) contacting said substrate comprising said surface with an acidic aqueous non-etching protector solution comprising (ii-a) one or more than one amino azole, (ii-b) one or more than one organic acid and/or salts thereof, (ii-c) one or more than one peroxide in a total amount of 0.4 wt-% or less, based on the total weight of the protector solution, and (ii-d) inorganic acids in a total amount of 0 to 0.01 wt-%, based on the total weight of the protector solution, wherein during step (ii) the total surface area of said surface is not increased upon contacting with the protector solution.

Invention relates to corrosion-inhibiting compositions and the process of using said compositions to protect metal from corrosion. The compositions comprise of sulfonates, a carboxylic-sulfonic acid metal complex, antioxidants, fluorinated copolymers, hydrophobic silanes and siloxane additives and solvent.

Methods are provided to inhibit corrosion in low hardness water systems. The corrosion inhibiting treatment comprises: calcium salts of low molecular weight polymer polycarboxylic acids. These calcium salts may be added preformed to the water system in need of treatment or formed in-situ in the system. This method of corrosion inhibition is not a source of addition phosphorous or heavy metal to the treated system.

Methods and compositions for inhibiting corrosion of a metal product are provided. The metal product can be contacted with water that includes at least one carbonate and/or bicarbonate salt, or otherwise has components that increase the alkalinity of the water. In addition, or as an alternative, the water can include a stannous corrosion inhibitor. The water can be evaporated off of a surface of the metal product to provide a residual of the salt on the surface and/or a protective stannous film on the surface.

Corrosion inhibitor compositions are provided that can include a mixture of one or more alkaline earth metals, one or more organic phosphates, one or more inorganic phosphates, optionally a dispersant, and hydroxyphosphono acetic acid and/or salts thereof and/or derivatives of hydroxyphosphono acetic acid and/or salts thereof. Methods of mitigating or inhibiting corrosion of metal surfaces are also disclosed. The methods can include the steps of adding a corrosion inhibitor composition as described in the present disclosure to a medium in contact with the metal surface and optionally to the metal surface before it is contacted by the medium.

Disclosed is an antifreezing coolant composition, which does not include glycol but includes environmentally friendly materials, such as a carboxylic acid salt, an anthranilamide compound, a corrosion inhibitor and a triazole compound. The antifreezing coolant composition may form a thin film on the metal surface in cooling systems for vehicles to thereby exhibit high corrosion resistance at low and high temperatures, superior antifreezing performance at low temperatures, and superior cooling performance at high temperatures.

Graphene quantum dots are functionalized by covalently bonding a corrosion inhibitor molecule thereto. In a useful method, a corrosion inhibitor compound is blended with a graphene quantum dot-tagged corrosion inhibitor compound, and the blend is applied to a metal surface, such as the interior of a carbon steel pipe. The blend inhibits corrosion arising from contact with produced water generated by hydrocarbon recovery from one or more subterranean reservoirs. The produced water having the blend dispersed therein is irradiated with a source of light having a selected first range of wavelengths, and the luminescent emission of the graphene quantum dot-tagged corrosion inhibitor is measured at a selected second range of wavelengths, thereby providing for real-time measurement of corrosion inhibitor concentration within the pipe.
