Cadmium Coating on Cylinder
Cadmium Coating on Cylinder
(OP)
Hello,
I have been suggested to use a cadmium coating on cylinder walls.
I have the impression cadmium is quite ductile, so it is maybe not the best way to cope with wear ...
What do you think ?
Thanks,
DVE

I understand it is very expensive, and is only used on gudgen pins and titanium bearing surfaces in valve stems etc, and only in very serious race engines, like Top Fuel and Nascar.
Bores can be done in Nikasil, and this is used for 500cc motor GP and formula 1 engines.

Also, be very very careful whom you select to Hone them. Nikasil or not, Honing is a precise art form that 1 in 10,000 engine builders understand and the same is true for the number of them that have reasonably clean/up to date equipment.

Is the cost of this coming down with higher volumes? Will it ever be an OEM procedure?

Yes, I checked again, suggestion was cadmium (to answer Swall) ... which supprised me as well.
So, before rejecting the idea, I wanted to share it on the forum. In its way, cadmium is a bit like tin and lead which are used on shell bearings (please, forgive me if I am wrong) and the idea was probably to offer the same advantages of shell bearings ...
