Foreword
This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives
for Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents.
This document serves as a replacement for QC/T 625-2013 Metallic Coatings and Conversion
Coatings for Automobile. In comparison with QC/T 625-2013, the main technical changes are
as follows:
a) The scope of application of metallic coatings and conversion coatings for automobile
is modified (see Chapter 1; Chapter 1 of Version 2013);
b) The provision on the thickness of the chromium coating of copper + nickel +
chromium and nickel + chromium electroplated coating is modified (see Table 2;
Table 2 of Version 2013);
c) The provision on the salt spray corrosion resistance of copper + nickel + chromium
electroplated coating on the plastic substrate is modified (see Table 3; Table 3 of
Version 2013);
d) The provision on the time that substrate corrosion appears on the corrosion resistance
of zinc electroplated coating is added (see Table 5);
e) The requirements for the surface friction coefficient of zinc electroplated coating are
added (see 6.5);
f) The provision that threaded fasteners shall comply with GB/T 5267.1 is deleted (see
5.5 of Version 2013);
g) The requirements for the surface friction coefficient of copper electroplated coating
are added (see 9.3);
h) The provisions on the thickness of zinc-nickel alloy electroplated coating and the
color passivation layer of zinc-nickel alloy electroplated coating are added (see Table
18);
i) The requirements for the time that zinc corrosion appears on the corrosion resistance
of zinc-nickel alloy electroplated coating are modified, and the provision on the time
that substrate corrosion appears on the corrosion resistance of zinc-nickel alloy
electroplated coating is added (see Table 19; Table 19 of Version 2013);
j) The requirements for the surface friction coefficient of zinc-nickel alloy electroplated
coating are added (see 17.4);
k) The provision on the thickness of zinc-iron alloy electroplated coating is added (see
Table 20);

3 Terms and Definitions
This document does not have terms or definitions that need to be defined.
4 Representation Method of Metallic Coatings and
Conversion Coatings for Automobile
The representation method of metallic coatings and conversion coatings for automobile mainly
consists of the following three parts (see Figure 1).
Use chemical symbols to represent the base metal or the main metal in the alloy matrix,
followed by a slash (/).
Use chemical symbols, Arabic numerals and lowercase pinyin letters to indicate the category,
thickness and type of coatings. If copper or brass containing more than 50% copper is used as
an intermediate coating, use the chemical symbol Cu to represent the copper coating.
The number after the symbol represents the minimum thickness of the coating, which is
expressed in (m).
EXAMPLE:
The steel substrate is coated with copper with a minimum thickness of 20 m, a nickel layer with a
minimum thickness of 30 m is plated on the copper, and ordinary chromium is coated with a
minimum thickness of 0.25 m on the nickel layer. Its code is: Fe/Cu20Ni30dCr0.25.
5 Copper + Nickel + Chromium and Nickel + Chromium
Electroplated Coating
5.1 Working Condition No.
The working condition No. is used to specify the harshness of the working environment of
coated parts.
The working condition No. of copper + nickel + chromium and nickel + chromium electroplated
coating is shown in Table 1.
