It's a metal; a really hard one. How can that not be detrimental to Fe, Al, Cu and Pb surfaces? Ti is FAR harder than those others. Why is it not abrasive? I can only presume that "titanium" is just the generic term being used, and it's actually some derivative thereof?
You're kidding, right? I thought everyone knew that molecules usually are composed of multiple elements.
And when you make compounds from elements the properties change drastically from single elements alone.
And, on this site, its also very, very obvious that when we say "there's zinc in oil" we mean as part of the ZDDP molecules, not pure elemental zinc.
Here, Ti is actually in a compound molecule with other elements.
"The measurements revealed that the antiwear enhancement comes from titanium chemically bound into the metal structure of the engine surface, forming a hard oxide, iron titanate." -- from the NIST article. Beginning with titanium dioxide, then forming iron titanate for the tribofilm.
1) I'm not a chemist
2) Really, I'm not a chemist
3) Elements are the building block of compounds; I think we agree here.
Ti is an element; can't be broken down to a sub-level (well, protrons, neutrons, etc, but it's most basic form is Ti).
What I was eluding to is that pure Ti is very hard and I doubt it's "only" Ti in oil in it's pure form. As I said, it's probably some derivative thereof; a compound that contains Ti in an altered state. What I want to know is ... well ... what is it in the tech speak? I am aware it's not a "pure" Ti; I'm asking what compound it is, using Ti as the forming basis?
I think we know what it isn't; it's not a pure form of Ti.
I want to know what it is.
Typical of advertising, they will boil it down to a half-accurate description that the dumb masses will hear and be able to regurgitate.
I'd like to know past that level.
I'd like to hear from someone in the additive/formulation industry; Molakule?
