6、rfung (Materials Testing Standards Committee), Working Committee NA 062-01-76 AA Galvanische berzge. Working Committee NA 062-01-76 AA recommends that the following be taken into account: Clause 3 of the original version of ISO 6158 does not refer to the European Standard on the specification of gen
7、eral requirements for electrodeposited coatings DIN EN 1403 as a terminology standard. Therefore, the sequence and content of the specifications given in Clause 4 of the present standard contradict in part the requirements of DIN EN 1403. NA 062-01-76 AA recommends that the wording specified in DIN
8、EN 1403 be used in cases of doubt. However, the requirements relating specifically to this document are to be met. New designations have been introduced in Subclause 5.4; NA 062-01-76 AA would like to point out that only DIN EN 1403 can apply as regards the letters “HT” for heat treatment. Because D
9、IN EN 1403 is not taken into account in ISO 6158 as mentioned above a relevant terminology is lacking in Subclause 6.4, which NA 062-01-76 AA recommends should be taken from DIN EN 1403.

Engineering chromium coatings, however, a
33、re generally thicker than decorative ones. Regular or conventional chromium is the type most frequently specified, but porous, cracked or specially profiled surfaces and duplex chromium are also applied to achieve oil-retaining or non-sticking surfaces, or to improve corrosion resistance. Electrodep
34、osited chromium coatings for engineering applications are most often applied directly to the basis metal to increase wear and abrasion resistance, to increase fretting resistance, to reduce static and kinetic friction, to reduce galling and seizing, to increase corrosion resistance, and to build up
35、undersize or worn parts. For protection against severe corrosion, nickel or other metallic undercoats may be applied prior to the electrodeposition of chromium, or the corrosion resistance of the chromium coating may be increased by alloying, e.g. with molybdenum. 4EN ISO 6158:2011 (E) DIN EN ISO 61
