Effects of Moisture and Other Vapours on Film Formation

There is some evidence that running-in of a film is improved in the presence of moisture, and this may again be due to the effect of increased friction in removing high spots in an unburnished film. This would in fact be a specific case of the general effect of moisture on film wear, which is to increase wear rate and reduce wear life Both effects are consistent with the effect of moisture in increasing friction, since in general any factor which increases adhesive friction will also tend to increase adhesive wear. 

There seems to be little specific information on the effect of other vapours on film formation or running in,
