ELECTROPLATING COATINGS

Designation: Z

Synonyms: White galvanized.

Price: from 10 rub. . per dm²

Purpose:  Yellow galvanizing on hangers is the main anti-corrosion coating for steel parts. Rainbow chroming provides significant enhancement protective characteristics of zinc. In terms of corrosion resistance, rainbow chromate films are second only to thick “olive” films.

Designation: Z

Synonyms: White galvanized.

Price: from 10 rub. per dm²

Purpose:  White galvanic zinc plating - one of the main anti-corrosion coatings on steel.Colorless chromium plating not only increases the protective properties of the zinc coating, but also increases the degree of gloss. The corrosion resistance of chromium zinc is lower than rainbow. Chromite film is environmentally friendly - it does not contain hexavalent chromium.

Designation: Z

Synonyms: Zinc yellow

Price: from 10 rub. per dm²

Purpose:  Galvanizing of hardware is carried out to protect them from corrosion. Coating on pendants  gives a protective layer that is more uniform in thickness, and the products do not hit each other. Galvanizing in a bell is more productive. Hardware with a tensile strength higher than 1380 MPa is usually not galvanically galvanized without heat treatment.

Designation: Zn

Synonyms: Yellow galvanized.

Price: from 10 rub. per dm²

Purpose:  Rainbow galvanizing is the main anti-corrosion coating for steel springs. Yellow chromate plating significantly increases the protective properties of the coating, second only to khaki passivation in terms of corrosion resistance. Springs with a tensile strength above 1380 MPa are usually not galvanized without heat treatment.

Designation: Z.black

Synonyms: Black galvanized stainless steel.

Price: from 10 rub. per dm²

Purpose:Blackening (black galvanized) stainless steel is a decorative coating and, in combination with oiling in industrial oils, water emulsions or polymers, has good performance characteristics. Blackening of stainless steel is often used on hardware: bolts, nuts, washers, studs, etc. to create a decorative effect without greatly increasing the size of the thread.

Designation: Zn.t

Synonyms: White galvanized.

Price: from 10 rub. . per dm²

Purpose: White galvanizing with heat treatment - anti-corrosion coating for high-strength steels. Colorless chromium plating of zinc coating improves the appearance and corrosion resistance of steel products. Heat treatment is necessary for dehydration in order to neutralize "hydrogen embrittlement".

Designation: Zn.black

Synonyms: Black galvanized

Price: from 10 rub. per dm²

Purpose: Galvanizing with black passivation is a decorative anti-corrosion coating on steel. Black galvanizing is used instead of chemical oxidation and is superior to it in all respects. At the same time, the protective properties of black zinc without oiling are worse than those of rainbow and olive.

Designation: Zn.olive

Synonyms: Green galvanized, olive zinc.

Price:  from 10 rub. per dm²

Purpose: Olive galvanizing - a powerful anti-corrosion coating for steel with the most durable chromate passivation "khaki". This type of chromating provides a significant increase in the protective properties of zinc due to the greatest thickness of the outer film compared to analogues. Olive galvanizing is most often used on military parts operating in harsh conditions.

Designation: Zn

Synonyms: Zinc with phosphate.

Price:  from 10 rub. per dm²

Purpose: Anti-corrosion coating with increased adhesion to paints. It has the same high corrosion resistance as rainbow zinc, but is superior in saline environments. According to GOST 9.305-84 with a thickness of 24 microns with oiling, it can be used instead of toxic cadmium coatings.

Designation: Zn

Synonyms: Yellow galvanized.

Price: from 10 rub. per dm²

Purpose:  Galvanic galvanizing of cast iron protects it from corrosion in atmospheric conditions and neutral, non-salty environments. The final rainbow chromatization increases the protective properties of the entire coating several times. Only olive chromate provides the best protection. Cast iron products are more difficult to process than steel products. This is due to the presence of a casting crust on them, the quality of which (density) can vary greatly. Cast irons with a porous casting skin are more difficult to coat. Also, on cast iron, the overvoltage of hydrogen evolution is lower, which facilitates this negative side reaction during alkaline galvanizing, unless special additives are used in the electrolyte.

Designation: Zn

Synonyms: White galvanized.

Price: from 10 rub. per dm²

Purpose:  Colorless galvanizing of cast iron is used to protect parts from corrosion in dry, heated rooms (light operating conditions). In addition to this, chromium plating slightly increases the degree of gloss, which is important for cast iron parts, because they often have a high roughness after casting. The coating is free of toxic hexavalent chromium. Otherwise the coating is similar to rainbow zinc.

Designation: Zn-Ni

Synonyms: -

Price: from 10 rub. per dm²

Purpose: Zn-Ni - modified anti-corrosion coating for steel. Due to the 12-16% nickel content in the alloy, the coating becomes harder, more resistant to corrosion and high temperatures. The main application of the coating is in the automotive industry.

Designation: Zn

Synonyms: White galvanized.

Price: from 10 rub. per dm²

Purpose:  Zn-Al-Cu coating is used primarily to improve the appearance of products. Corrosion protection also appears to some extent, although, in essence, Zn-Al-Cu itself already includes a large amount of zinc.

Designation: Sn-Bi

Synonyms: Tinning.

Price: from 10 rub. per dm²

Purpose:  Tin coating on current-carrying copper busbars and flexible connections is used for their </undefined: p>protection from oxidation, stabilization of transition resistance, giving a highly decorative commercial appearance and eliminating direct contact of the copper busbar with aluminum or galvanized steel (undesirable galvanic couple). Tin-bismuth improves solderability (the solderability of the surface lasts for about a year) and creates easily break-in layers with movable electrical contacts. Adding bismuth to the coating slows down the transition of the plastic white modification of tin into powder gray at sub-zero temperatures below -30°C. Bismuth also suppresses the process of “needle formation,” which is important in electronics products.

Designation: Sn-Bi

Synonyms: Tinning.

Price:from 10 rub. per dm²

Purpose: Tin coating on copper busbars up to 3 meters is used to protect against corrosion, stabilize transient resistance, and prevent direct contact of the copper busbar with aluminum and galvanized steel (unwanted galvanic couple). Tin-bismuth improves solderability and creates easily break-in layers with movable electrical contacts. The coating improves the appearance of the products. Adding bismuth to the coating allows you to slow down the transition of the plastic white modification of tin to powder gray at temperatures below -30°C.

Designation: Sn-Bi

Synonyms: tin coating, tinning, tin plating

Price: from 10 rub. per dm²

Purpose:  Tin coating is used to prevent direct contact of stainless steel with aluminum and copper (undesirable galvanic couple), to facilitate the running-in of parts, to seal threaded contacts and to ensure solderability. Adding bismuth to the coating allows you to maintain solderability for up to 1 year, slow down the transition of the plastic white modification of tin to powder gray, and eliminate needle formation during storage.

Designation: Sn-Bi

Synonyms: Tinning.

Price: from 10 rub. per dm²

Purpose:  Tin coating on copper and brass it is used to protect against corrosion, improve appearance, improved solderability, protection of electrical contacts from oxidation and stabilization of contact resistancecreation on rubbing surfaces easily break-in layer.The addition of bismuth to the coating allows maintain solderability for up to 1 year,slow down the transition of the plastic white modification of tin to powder gray,slow down the needling.
