That's a lovely oxymoron! ;)

The chrome on the housing is almost certainly normal hard chroming (same as you get on things like motorcycle fork stanchions). The side plates are nitrided, which is applying heat in a nitrogen rich atmosphere to harden the surface.

Somewhere at sometime I read that it's a special chroming process that has an oil retentive finish, then maybe I dreamt that I read it!

Awesome thanks!

I was in a discussion with an old engineering acquaint who's very handy due to them having every type of machine tool imaginable! We somehow got into speaking mineral and synthetic oils and how synthetics react to chrome surface types!

According to one of the papers I have:

Micro Channel Porous (MCP) Cr-plating.
Pinpoint pores for better oil retention.
Fluorocarbon resin coating.

Not entirely sure if that's applicable to Renesis housings or other rotary housings or some other test engines atm.

Aside from the Flourocarbon resin coating then that's what I read somewhere

To be sure you are, or is your, or you're correct
