This specification covers the requirements for electrodeposited
zinc iron alloy coatings on metals.
This specification defines performance requirements for various electrolytically deposited zinc-cobalt, zinc-nickel and zinc- iron alloy coatings and their associated conversion coatings, used to enhance corrosion resistance on ferrous parts. This specification applies for either a rack or barrel plating process. The conversion coating material specified herein shall contain no hexavalent chromium as it is forbidden by applicable government and industry regulations.
This European Standard specifies requirements for electrodeposited coatings
of zinc on iron or steel with supplementary treatment.
This European standard does not specify chromate finishes which are required
only for improving the adhesion of paints or varnishes.
NOTE: This European standard is not intended to be used alone, but is the
complement of EN 1403. It is necessary for the purchaser to specify the
zinc electrodeposited coating in accordance with the designation as
specified in EN 1403.
This standard specifies the plating and performance requirements for various zinc-cobalt, zinc-nickel and zinc-iron alloy electrodeposits and their associated chromate coatings, used for enhanced corrosion resistance on ferrous parts.
This standard specifies the requirements for the protection of zinc and zinc
alloy coatings on steel, against the formation of white corrosion products.
This specification covers the basic requirements for barrel or rack electrodeposited zinc alloy plating over a ferrous substrate. Four alloy plating’s are covered by this specification: zinc cobalt, zinc nickel, zinc iron and tin zinc. Zinc alloy plating is especially suitable for small to medium ferrous parts such as castings, fasteners, stampings, clips and other parts where levels of corrosion protection exceeding pure zinc are required. Table 1 lists the zinc alloy finishes covered by this specification and their alloy concentration limits and % nominal. NOTE: This finish is not recommended for applications where white corrosion is a cosmetic concern.
This specification covers the basic requirements for a barrel or rack electrodeposited zinc alloy plating system over a ferrous substrate. A plating system consists of; zinc alloy plating, a zinc-alloy surface treatment (e.g. trivalent chromium conversion coating), and may include a post treatment. All zinc alloy surface treatments and post treatments must be hexavalent chromium free. Four alloy plating’s are covered by this specification: zinc-cobalt, zinc-nickel, zinc-iron and zinc-cobalt-iron. Zinc alloy plating is especially suitable for small to medium ferrous parts such as castings, fasteners, stampings, clips and other parts where levels of corrosion protection exceeding pure zinc are required. Table 1 lists the zinc alloy finishes covered by this specification and their alloy concentration limits and % nominal. NOTE: This finish is not recommended for applications where white corrosion is a cosmetic concern.
This standard covers chromate conversion coatings on electroplated zinc
alloy coatings containing nickel or iron and/or cobalt that are applied to
ferrous substrates. Such coating systems serve as corrosionprotection
and/or as decoration.
This standard specifies requirements for corrosion resistance under various
service conditions, as well as for the minimum local coating thickness.
See ISO 4042 for dimensional requirements for electroplated threaded
This standard does not apply to semi finished products.
This specification defines performance requirements for an electrolytically deposited alloy coating of zinc/iron. This specification was released originally to define performance requirements for zinc/iron alloy coatings where corrosion protective and/or decorative finishes on ferrous surfaces are required. A supplementary surface treatment (of trivalent chrome and/or hexavalent chromium free coating) must be applied to coated parts to retard formation of white corrosion products.
This specification covers the basic requirements for barrel or rack electrodeposited zinc alloy plating over a ferrous substrate. Various alloy platings are covered by this specification with supplementary treatments. Table 1 lists the zinc alloy finishes covered by this specification.
This standard specifies the electroplating to be performed for purposes of corrosion prevention, rust prevention, and decoration. Functional plating, to be performed for wear prevention, is excluded. Inclusion of hexavalent chromium in the coating shall be prohibited beginning on December 31, 2005.
This standard applies to iron and steel automotive parts coated with zinc iron alloy plating (thereafter referred to as plating) for decorative purposes to prevent corrosion. The coated surface is referred to as the effective surface. Specifications in this standard are applicable only to the effective surfaces. Corrosion preventive qualities for surfaces other than the effective surfaces are to be determines by the personnel involved in the testing. Effective surface designation is as specified in the illustrations (or the inspection standards).
This specification defines the performance criteria and test method for evaluating zinc iron (ZnFe) plating’s over ferrous substrates.
This standard covers electroplated zinc-iron alloy coatings (hereinafter referred to as plating) with black chromating, provided for the purposes of corrosion protection and better appearance in black color on base steel and iron for automobile parts.
This standard covers electric zinc-iron alloy plating (hereinafter referred to as plating) provided over black chromate coatings containing no hexavalent chrome for the purpose of corrosion protection of base steel and iron for automobile parts. The parts made of materials provided by this specification shall conform to prohibitions and restrictions for substances of environmental concern.
This standard applies to the identification of general surface protection
types of vehicle parts and units in drawings and technical documentation.
Separate Technology Supply Specifications (TL Standards) apply to special
surface protection types without identification by surface protection code
(see Appendix A.2.)
This standard covers electroplated coatings of zinc-iron with chromating for the protection against corrosion on threaded and non-threaded parts of iron and steel. It also describes subsequent treatment of threaded parts.
This company standard is valid for all ZF Lemförder plants (referred to as
ZFLM in the following) and their suppliers. Essentially, no higher-quality
surface protection than that demanded by the customer is
selected. On selection of the type of surface protection, suitability for
the intended area of application must be checked in advance, see LMN 50
Suppl. 8. If more extensive requirements are defined in standards or on the
drawing, these are not ruled out by specifying surface protection according
to this standard.
