Abstract: A method for application of an adherent nickel plate to titanium includes steps of surface preparation, deposition of nickel from a plating solution, and a final treatment. The surface preparation steps include a hydrochloric acid dip, a nitric acid/hydrofluoric acid activation, treatment to slow the re-formation of an oxide layer, and deposition of a nickel strike. The treatment to reduce oxide formation may be accomplished without application of a current, in a solution of acetic and hydrofluoric acid, in which titanium alloy has been electrolytically dissolved. Alternatively, the treatment may be performed with the piece to be plated made anodic in a solution of acetic acid and hydrofluoric acid.

Abstract: Un procédé pour appliquer sur du titane un placage au nickel adhérent consiste à préparer la surface, à déposer du nickel contenu dans une solution de placage, et à procéder à un traitement final. Les étapes de préparation de la surface comprennent le trempage dans de l'acide chlorhydrique, l'activation à l'acide nitrique/acide fluorhydrique, le traitement pour ralentir la reformation d'une couche d'oxyde, et la réalisation d'un dépôt amorce. Le traitement pour réduire la formation d'oxyde peut s'effectuer sans application d'un courant, dans une solution d'acide acétique et fluorhydrique, dans laquelle a été dissous par voie électrolytique l'alliage de titane. Dans une variante, on peut effectuer le traitement en rendant la pièce à plaquer anodique dans une solution d'acide acétique et d'acide fluorhydrique.
Abstract translation: 将钛应用于粘附性镀镍的一种方法是制备表面，沉积镀液中含有的镍，并进行最终处理。 表面处理步骤包括浸泡在盐酸中，硝酸/氢氟酸活化，处理以减缓氧化层的重新形成，并且沉积 底漆。 用于减少氧化物形成的处理可以在不施加电流的情况下在乙酸和氢氟酸的溶液中进行，其中钛合金已经电解溶解。 在一个变型中，可以通过将该部件阳极电镀在乙酸和氢氟酸的溶液中来进行处理。
