Quote:I have a question for those in the know. I'd expect there to be some kind of galvanic reaction between the carbon fiber and the Ti. What effect would that have on the durability of the handle?
Cino thanks for asking...never been asked this before but a fair question, here is a good article that discusses this:
https://www.corrosionpedia.com/galvanic-...ers/2/1556
Titanium is extremely resistant to corrosion and Graphite(Carbon) is even more resistant, here is a chart that ranks the material(Chart 1):
https://www.corrosionpedia.com/an-introd...ion/2/1403
The risk is minimal with Titanium/carbon fiber of any galvanic corrosion(both noble materials) and the article above recommends using Titanium and its alloys to reduce galvanic corrosion. We also offer a version of this handle in stainless...the article above discusses the issue of pitting corrosion with lower grades of stainless such as 304. 303 is even more likely to corrode...We however use a highly corrosive resistant "marine grade" 316L stainless steel in all our razors.
Another note to mention is that in our design of the R3 handle, the carbon fiber does not actually touch the titanium(or stainless)...there is about a +.1mm gap that is filled with a specially designed epoxy for bonding composites and metals (made by 3M...a local Minnesota company!) that acts as an insulator and adhesive. The epoxy takes about 2 weeks to cure...
Interesting fact but it was a wet shaver out of the UK who works on F1 race cars who gave us tips and helped us to make this bond...in our first version of this handle we used small "micro-beads" in the epoxy to create this gap.
This is our perspective from a design point of view. Thanks again for asking...
