DIN EN 2132:2017-06

This European Standard specifies the chromium plating of parts made of carbon steels and alloy steels used in aerospace construction. It specifies: a) requirements for pretreatment, b) the method of electrodeposition of the chromium, c) maximum and minimum thicknesses, d) heat treatment, e) qualities required of the coating, f) methods of inspection. Chromium coatings are applied in aerospace construction for one or more of the following purposes: a) resistance to wear, b) resistance to corrosion and wear, c) the building-up of worn or over-machined parts. Chromium plating should not normally be used on parts which become hotter than 450 °C in service. When chromium plate is to be applied to steels of strength Rm (max.) > 1450 MPa which are subject to fatigue stresses in service, a treatment schedule together with inspection procedure and test results establishing its validity shall be sent to the Official Service (Procurement Authority), for approval.
