Amis de la science et des effets spéciaux BONSOIR.
Un nouveau procédé physico-chimique permet d'obtenir un effet irisé sur le chrome.
Dans le style pot d'échappement de Kawazaki.
En voici un exemple sur les parties métalliques d'un prototype DW.
(edit: en fait tout est métallique mais le fut en alu brut n'est pas traité)




Je sais qu'il y a des fortiches en anglais ici,vous pouvez nous traduire ça?
"The process is Vacuum Coated over the Chrome Plated parts, this coating is Titanium Oxide and can be deposited over Satin or high Polished Chrome Plated products. The is the same process that's used on all Major Hardware like Faucets and Door Knobs.. Like Kohler,Moen, Delta and Schlage Locks and sold as the "Lifetime Finish" to look like Brass and Nickle
PROCESS...
Physical vapor deposition (PVD) refers to any vacuum process in which a source material, in a vapor state, is condensed into a substrate (part to be coated) to form a solid material (coating). The vapor may be obtained either by evaporation or by sputtering of a source material.
Physical vapor deposition (PVD) enable when adding reactive gas on the coating chamber (O2, N2, CH4, B2, H6, H2S) to form, at low temperature, oxides, nitrides, carbides, borides, sulfides based coatings."
Avec un petit rhodo "cosmic vomit" ou "abalone", ça peut faire très très mal
