Coating method for Titanium dioxide?

As part of an experiment, I need to coat one side of a 150mm metal
disk with TiO2. The metal can be anything that will produce the best
result. Presently I have aluminium.

What is the best option in terms of additives and technique for the
following two outcomes.

1. I simple immobilized layer painted (rolled) on with a
self-hardening binder that will more or less homogenize the dielectric
within the entire coating. What generic binder would best suit?

2. A chemical or surface applied means that retains some
semiconductive properties without resort to sol gel, sintering, etc.
How effective is conductive paint as a binder for such a process.
Would abrading the metal surface prior to improve efficiency?

Thank you for your suggestions.

Too much work and too expensive.
Anodize it; the oxide *is* the surface and the controls are easy
(surface contamination, surface porosity, surface smoothness, voltage,
current, time, and PH to mention some of the important and controllable
parameters).
