Anodising is a method of coating objects made of aluminium with a protective oxide film, by making them the anode in an electrolytic bath containing an oxidising electrolyte. Results 1—10 of 34 for katodna zastita. Additives are often present in small amounts and are used for a variety of purposes, as katodnna preventing corrosion, zatsita polymers, and preserving and improving food.

Groundbed is a buried item, such as junk steel or graphite rods, that serves as the anode for the cathodic protection of pipelines or other buried structures. Iron which is oxidises will immediately be reduced back to iron.

The origin of the name comes from the Latin word alumen meaning alum. The iron pipe will be connected to a more reactive metal such as magnesium through cooper wires, the magnesium will donate its electrons to the iron preventing it from rusting.

Acylaction reaction involves the introduction of an acyl group RCO- into a compound.

There are two major variations of the cathodic method of corrosion protection. Additive is a substance added to a material to improve its properties in some way. Metal reacts violently with oxidants. The anode corrodes, thereby providing the desired sacrificial protection.

Streams of beta particles are known as beta ray or beta radiation.

Cathode rays are streams of electrons. The protected metal becomes the cathode and does not corrode. The introduction of an acetyl group CH zxstita CO- is acetylation, a process used for protecting -OH groups in organic synthesis. Anodising can also be used to produce a decorative finish by formation of an oxide layer that can absorb a coloured dye.

Cathode ray is a negatively charged beam that emanates from the cathode of a discharge tube. Streams of beta particles are known as beta ray or beta radiation. The sacrificial anodes must be replaced periodically as they corrode. Cathodic protection is a process in which a structural metal, such as iron, is protected from corrosion by connecting it to a metal that has a more negative reduction half-cell potential, which now corrodes instead of iron.

An alkyl halide is reacted with an alcohol or a carboxylic acid anhydride e. Beta rays may cause skin burns and are harmful within the body. By protection of the environment, the following is ensured: The origin of the name comes from the Latin word alumen meaning alum.

A thin sheet of metal can afford protection to the skin. Beta rays may cause skin burns and are harmful within the body.

Aluminium is zasrita by electrolysis from bauxite. Additives are often present in small amounts and are used for a variety of purposes, as in preventing corrosion, stabilizing polymers, and preserving and improving food. From Environment protection law of the Republic of Croatia: Pieces of zinc or magnesium alloy are attached to pump bodies and pipes.

A thin sheet of metal can afford protection to the skin. Cathodic protection is a process in which a structural metal, such as iron, is protected from corrosion by connecting it to a metal that has a more negative reduction half-cell potential, which now corrodes katodan of iron.
