Abstract: Conventional antiwear agents
for lubricants are active chemicals, such as sulphides,
phosphates and chlorinates. The action mechanism of these
antiwear agents is a kind of "conrolled corrosion". Having no
corrosion to metals, some new antiwear agents containing
B, N, Si, Al, Sn are named "non-active antiwear agents" by authors.
Based on the results of surface analyses, the action mechanism
of non-active antiwear agents is suggested that the non-active
atoms such as B, N, C, Si, Al, Sn permeate into the surface of metal
to form a protecting layer reducing friction and wear.
Key words:
Lubricant Non-active antiwear agent
Permeating layer
