Step 1
Clean
To remove surface residues and assure uniform etching/polishing.
Non-aggressive,
effective on post-processing soils.
Step 2
Deoxidize & Etch
To remove oxides with controlled removal
and polishing of base metal. A variety of deoxidizers
for a variety of substrates and situations.
Step 3
ElectroPolish
To obtain a polished surface. Includes Unique room
temperature electropolishes (no cooling necessary).
Step 4
Passivation
To build a protective oxide layer for increased
biocompatibility. Nitric or citric acid based
chemistries are commonly used.
Nickel Titanium, better known as Nitinol, is a biocompatible metal alloy often used in catheters, stents, and other medical devices.
Nitinol requires specific chemical solutions to ensure effectiveness and decrease the risk of rejection.RBP Chemical Technology is the leader in development, manufacturing and the distribution of specialty chemical processes for the cleaning and passivation of Nitinol and other alloys used for implanted medical devices.
