2006
Full-body
Electroplating (double-sided)
• immersion in zinc electrolyte under current • zinc layer 8 - 16 microns • use of branded USIBOR steels in anti-strike zones • introduction of laser welding and rations of seams
Result of processing: Good Car's 18 years old.Considering the car's age and quality of the zinc processing, under normal operating conditions body corrosion spreads in initial stage.On such cars rusting is already noticeable in hidden cavities and joints.
2007
Full-body
Electroplating (double-sided)

• immersion in zinc electrolyte under current • zinc layer 10 - 12 microns • includes a share of aluminum body elements
Result of processing: Good Car's 14 years old.Considering the car's age and quality of the zinc processing, under normal operating conditions corrosion of body just begun.It's difficult to notice if car has not been hit or scratched.
2011
Full-body
Electroplating (double-sided)
• immersion in zinc electrolyte under current • zinc layer 10 - 12 microns • includes a share of aluminum body elements
Result of processing: Good Car's 13 years old.Considering the car's age and quality of the zinc processing, under normal operating conditions corrosion of body just begun.It's difficult to notice if car has not been hit or scratched.
2012
Full-body
Electroplating (double-sided)
• immersion in zinc electrolyte under current • zinc layer 10 - 12 microns • includes a share of aluminum body elements
Result of processing: Good Car's 12 years old.Considering the car's age and quality of the zinc processing, under normal operating conditions the first corrosion will begin in 1 year.
2013
Full-body
Electroplating (double-sided)
• immersion in zinc electrolyte under current • zinc layer 10 - 12 microns • includes a share of aluminum body elements
Result of processing: Good Car's 11 years old.Considering the car's age and quality of the zinc processing, under normal operating conditions the first corrosion will begin in 2 years.
The information in table is collected from open sources and may contain errors.About sources
Full-body — the car body is fully processed, including hidden and hard-to-reach cavities.
•
Partial — all nodal points and most vulnerable parts of the car body, thresholds, bottom, bottom of the doors are processed.
•
Nodal points processing — includes only processing of welding places, fasteners, stamping and other small parts.
Over years the processing is changed. The younger car the better it's galvanized!
Galvanizing methods
•
Hot-dip Galvanizing — best method (high corrosion resistance, resistance to mechanical influences, partial regeneration).
•
Electroplating — good method (less corrosion resistance that matches perfectly with the paint and primer).
•
Zincrometal — acceptable method (metal with an elastic coating on a zinc base, low anti-corrosion properties, low resistance to mechanical influences).
•
Cold Galvanizing — bad method (anaphoretic soil with an admixture of zinc is not able to resist corrosion).
Steel with a protective coating based on zinc - zincrometal, it contains three components:
1 — zincrometal (zinc solution in epoxy resin) 10-20 microns
2 — dacromet (zinc variance inchromic acid water solution) 2-5 microns
3 — sheet of steel
The presence of zinc particles in ground covering the car body does not affect it's protection and is used by the manufacturer for word "Zinc Coated" in advertising.
Testing
Test results of cars that came off the conveyor with the same damage (cross) on the bottom of front right door are presented below. The tests were carried out in laboratory. Conditions in a chamber with hot salt fog for 40 days correspond to 5 years of normal operation.
Car with Hot-dip Galvanizing (zinc layer 12 - 15 microns)
Over the years manufacturers have improved the galvanizing technology of their cars. The younger the car the better it is galvanized!
•
A coating with a thickness of 2 to 10 microns (micrometers) provides excellent protection against the occurrence and spread of corrosion damage.
•
The destruction rate of the active zinc layer in the place of damage to the car body is from 1 to 6 microns per year. Zinc is more actively destroyed at elevated temperatures.
•
If the manufacturer does not add "full-body" to the term "galvanizing", it means that only impact-prone elements have been processed.
•
Pay more attention to the presence of a manufacturer's warranty on the car body than loud phrases about galvanizing from advertising.
