New way to mark Titanium implant
Jérôme Berjonneau – 10/12/2015
Product
Color marking can be applied on anodizing parts :
This new process is able to mark :
• Everything you want on implants like logos, shapes, serial numbers, datamatrix….
• With the size you want
• With several colors
• Without altering mechanical properties of the implant.
=> Marketing / functional surgery

Plasma Polishing
Jérôme Berjonneau – 10/12/2015
Plasma polishing technology
Plasma polishing : electrochemical process generates plasma skin onto the part
A new technology for cleaning (organic and inrorganic), deburring and polishing metallic
surfaces (Ra < 0.03µm) and removing oxide layer
(Titanium, Nitinol, CrCo, Stainless Steel…)
+
It is a fast (10s -> 80s) and low cost surface process
Plasma Environment friendly electrolyte : 97 % of water + 3 % of salts
+
+
+
Part +
Electrolyte
Simple : 2 baths required only:
1/ electrolyte bath (97% water + 3% salt), thermally regulated (80°C, range 4°C), electricity
supply (200-400 V, 20A/dm²)
2/ Rinsing bath : only to remove salts
=> faster, more environment friendly, easier to rinse and to automatize than Electro polishing

Plasma polishing process definition
•
•
Process definition at Cestas (on Titanium, Nitinol and Stainless steel)
Plasma polishing line designed
Objective : to define and to optimize the future applications in Stryker plants
Potential Applications :
• Automated Cleaning and deburring parts after machining (in place of tumbling) / leadtime
• Anodizing preparation : could substitute lessiviel step and pickling step before anodizing / cost & safety
• Removing oxide layer after heat treatment or the anodized oxide layer : rework is possible / leadtime &
quality
• Polished implants : new design…
• Substitution of a classic electropolishing process with acid bath (recycling and wastes heavy to manage) /
safety
=> Adapted for complex geometries and small sizes implants
Jérôme Berjonneau – 10/12/2015
Ex1 : stainless steel blade - Comparison with electropolishing
 Plasma polishing can deburr
blades and remove machining
trace without remove lot of
thickness
 Electropolishing : burrs not
completely removed
Jérôme Berjonneau – 10/12/2015
Ex2:Neurovascular nitinol tube with different processing time
 Impact of the process on neurovascular tube. At left raw tube, at
right treated parts with different treatment time
 The longer the process time is the more the angles are broke
Jérôme Berjonneau – 10/12/2015
Others
Visual Management Application : Visual indications from instrument colors for surgery.
How to anodize stainless steel
Anodizing without pickling : currently pickling stage is performed to remove natural oxide and generates
withdrawal. A new process has been developed internally to substitute this stage without any withdrawal
impact. This new treatment brings a shiny aspect
Jérôme Berjonneau – 10/12/2015
Automation
Automatisation de l’ensemble de la finition des
implants : dégraissage, sablage, anodisation
couleur (Type 3), assemblage, marquage laser,
contrôle et logistique
Concept : ensemble de petites cellules : flexible
(Légo)
Scope
Déploiement sur l’ensemble des sites
européens.
Défis techniques :
• Anodisation type 3 en Panier
• Anodisation type 2 (micro arc) : aspect gris /
génère caractéristique mécanique à la pièce
(auto lubrifiante)
