Abstract

Die Erfindung betrifft ein Verfahren zur haftfesten Metallisierung von Titan oder Titanlegierungen durch außenstromlose Abscheidung einer Nickel-Phosphor-­ Legierung mit anschließender Wärmebehandlung zur Ausbildung von Nickel-Ttan-­ Diffusionsschichten, dadurch gekennzeichnet, daß die danach noch vorhandene Nickelschicht haftfest metallisiert wird. The invention relates to a method for the adhesive metallization of titanium or titanium alloys by electroless deposition of a nickel-phosphorus Alloy with subsequent heat treatment to form nickel-titanium Diffusion layers, characterized in that the still existing afterwards Nickel layer is metallized adherent.
