Interesting on a number of fronts...
* tribofilms are formed by reacted ZDDPs;
* replacement tribofilms require a reserve of unreacted ZDDP;
* different tribofilms based on temperature/surface conditions;
* and what was interesting between the AlSi and steels was that more reactive surface oxides seem to help
* AlSi, some of the "wear" appeared to be the silicon particles being forced down into the softer Al matrix
* second paper talks about the reduction in ZDDP efficacy in fully formulated oils due to the actions of inhibitors and detergents.
