Anodised Fbl Learn more. Chromium VI -compounds could be used in the past 845 the intermediate layer between the metallic coating and an organic finish.
For chromium VI -free coatings, the coating corrosion in the area formed after coating the component surface is generally not evaluated. The resulting measures shall be specified by the coater. Measures shall be derived from this, which serve to reliably minimize the quantity of hydrogen ingressing into the material during the process, and which enable a regular periodic examination of the efficiency of such measures.
Page 14 DBL For particularly critical parts, a switch shall be made to DBL and acid-free pretreatment.
The Holzapfel Vbl plates zinc iron according to the following standards: Surfaces – Anti-corrosion surfaces – Zinc-iron. Zinc-iron black blackcor Learn more. Page 11 DBL The stated requirement values — transferred to the procedure of this DBL — are in many cases comparable and currently represent state-of-the-art technology.

Preloading tests on real-life components that have been zinc-coated in a deformed fixture, in which the component is subjected to stress close to the weld seam through stresses in the yield strength area. Requirement for concrete indication of substance of passivating and sealing agents used by the supplier in xbl ISIR? Passivations are available in black or transparent 851.

Chrome Copper Chrome plating gloss, semi-matt Eloxal. Zinc-nickel platings were developed as a result of increasing requirements with regard to corrosion protection, in particular from the automotive industry, against exposure to temperature, road salt and climatic conditions. Before commencement 84551 production deliveries, the coater shall determine and record the complete pre-treatment and coating process, the physical data treatment periods, temperatures and the composition of all process chemicals, and, if required, optimize them.

Systems specially designed for your component. Page 6 DBL For this ebl, alongside the corrosion protection, attention shall also be paid to any possible changes in surface-specific functional properties in comparison to coatings containing Cr VI. More information about zinc-nickel? The product actually used for the creation of the passivation designation, manufacturer shall be indicated. The following product versions have been removed: Times generally 88451 during testing as per DIN SS for base material corrosion are distinctly higher than the test dl stipulated by this DBL of h.
These product versions may therefore only be used where the prohibition of Cr VI -compounds in corrosion protection coatings is not of relevance to the selected components see hereto also the notes in Section 1 of this DBL.
Where sealants are used, the product employed shall also be indicated designation, manufacturer. May 3 3. Page 2 DBL Chrome Copper Chrome plating gloss, semi-matt Eloxal.
For this reason the Cr VI -free product versions contained in the following table, which shall comply with these statutory requirements, are marked specially with the supplement Cr VI -free.
May Following the required test period as per DIN SS, remove the component from the test cabinet, rinse with demineralized ebl and then dry before the assessment, e.
Page 10 DBL We coat zinc-nickel black amongst others according to the following standards: Automotive and supplier industry e. Screws, bolts and nuts with coarse-pitch or fine-pitch thread, which are manufactured according to this DBL and not according to DBLddbl always be treated with antifriction agent, insofar as this is not ruled out by other reasons, for example the need for an additional coating with adhesives.
Headquarters of the Holzapfel Group Phone.: For notes on corrosion dbo and recommendations for various application cases, see Tables 2 to 4. Furthermore, the following information applies: Preservation of uncoated internal surfaces, for example the inside of pipes, as well as heat treatments tempering to remove hydrogen after the coating process, are offered to complement our range.
