World without rust. (1979)

Alternation of personnel for the production of material values.

The combine harvester harvests.

The helicopter carries the cargo.

A train is coming.

Port.

Ship.

Scrap yard.

The caterpillar eats the leaf of the plant.

Ore.

The connection of metal with non-metals of the Earth's crust and atmosphere.

Open pit mining of ore.

Metal casting.

The finished metal is returned to the environment where it was already in an oxidized state.

Such a return of metal to chemical compounds is corrosion.

This is a law of nature.

A plaque on the landing stage building, about its construction under the leadership of Honorary Academician Vladimir Grigoryevich Shukhov.

The effect on a copper coin of a strong and weak solution of nitric acid.

We lower the steel part into the solution.

In a weak solution, there is an active process of corrosion.

An oxide film formed in a strong solution, which stopped the process of corrosion.

Passivation has occurred.

This process is similar to the formation of patina on copper products.

The iron roof in the city is destroyed faster than the same outside the city.

Exhaust gases of cars.

Experience with a steel spoon, when the impact of an aggressive environment is simulated, the spoon is destroyed.

Construction site.

Metal structures on the construction site.

Constructions of bridges over rivers.

Metallurgical production.

Scale.

Money from metal losses is considered.

Processing of hot metal is not in oxygen, but in a mixture of gases.

Metal of the highest quality comes out of the metal processing device under the protection of a gas mixture.

New buildings.

Reinforcing steel in construction.

Concrete protects the metal from rust, but the joints come out.

Welding is performed.

Corrosion of metal after several years on the embedded part.

One of the solutions to the problem is aluminum coating and processing

ferryboat.

Author's certificates of Soviet scientists for the development of corrosion protection.

A piece of concrete with reinforcement from the collapsed ceiling in the building.

Salt with snow on the wheels of cars fell on the floor of the building, penetrated into the ceilings and corroded the fittings.

An 18-meter farm collapsed.

Part of the building collapsed.

Sea dock.

Production facilities.

Control panel for complex production.

Nuclear power plant.

Ships in the ocean.

The plane after the accident.

High-voltage lines.

Mangled parts at the Caspian oil wells.

Scientific equipment.

New problems - corrosion cracking.

He succumbed to the most necessary materials now - stainless steel, alloys based on aluminum, copper and magnesium.

Aircraft under construction.

Progress in this industry became possible only after effective means of corrosion protection of light alloys were invented.

Assembly of the aircraft body.

Picking - ulcerative or pitting corrosion.

A sample of the dive.

Knife corrosion, which forms next to the weld in the stress zone.

The corrosion is intercrystalline, the metal crumbles into individual grains.

Losses from corrosion annually up to 14 billion rubles.

Soviet money in a bank vault.

Storing money.

Removal of money from the vault.

Scientists engaged in the fundamental theory of corrosion.

Industrial enterprise.

Exhibition of proposals to combat corrosion.

Varnishes, paints, enamels.

The body of the car is covered with enamel.

The body is installed on the car.

Anti-corrosion treatment of machine parts.

Car assembly line.

Traffic in Moscow.

The cathedral.

The dome of the building in Peterhof, Leningrad region.

Fountains of Peterhof.

Sewage treatment plants.

Metallurgical, chemical and pulp and paper enterprises.

Inhibitors, substances that slow down the rate of corrosion.

They are placed in an aggressive environment, and they create a thin protective film.

Industrial equipment.

Dump truck.

Tanks.

Ship.

Offshore well.

Drilling rig.

Rusted borehole equipment.

Only inhibitors saved the drilling rigs.

Inhibited paper.

Details are wrapped in it, prolonging the storage and transportation time.

Stainless steel.

The range of its application.

In the production of stainless steel, many expensive additives are introduced into it.

A method of adding additives to the surface layer is being developed.

To protect power lines, a method of spraying protective coatings is being developed.

Spacecraft.

Samples of anodic corrosion protection.

Electrochemical protection.

Corrosion in aggressive environments is often an electrochemical process that can be controlled using the voltage between the metal and the solution.

Samples of such exposure.

Electrochemical protection installations.

Offshore oil fields are now protected by electrochemical protection.

A worker lowers an electrode made of a special zinc alloy.

Welding it to the overpass, the worker collects, as it were, a galvanic bath, which provides protection for the entire overpass.

Pipeline construction, electrochemical protection is also used there.

Turbine hall of the power plant.

Overpass.
