Title (EN) METHOD OF CORROSION-RESISTANT PLATING
(FR) PROCEDE DE PLACAGE RESISTANT A LA CORROSION
Abstract: front page image
(EN)A method of providing a highly corrosion-resistant electroplated film, which comprises first nickel plating a material to be plated directly or after subjecting it to underplating, then subjecting it to high stress nickel plating and subsequently to final luster nickel plating, and finally conducting finish plating such as chromium plating. Unlike those formed according to a conventional microcracked chromium plating method wherein chromium plating is directly applied to form microcracks in the chromium film after high stress nickel plating, the thus formed highly corrosion-resistant plated film does not contain microcracks in the final film such as chromium film. Nevertheless, it exhibits excellent corrosion resistance.
(FR)Un procede d"obtention d"un film d"electrodeposition hautement resistant a la corrosion, qui comprend un premier nickelage sur un materiel a plaquer directement ou apres l"avoir soumis a un sous-plaquage, puis en le soumettant a un plaquage sous forte tension et ensuite a un nickelage final de lustrage et finalement en effectuant un plaquage de finition tel qu"un chromage. A la difference de ceux formes de facon conventionnelle selon une methode au chrome dans laquelle le chromage est directement applique pour former des micro-fissures dans le film de chromage apres un plaquage en nickel a forte tension, le plaquage de film hautement resistant a la corrosion ainsi obtenu ne presente pas de micro-fissure dans le film final tel qu"un film de chrome. Neanmoins, il presente une excellente resistance a la corrosion.
