Abstract: With the help of direct
observation of wear, the processes and mechanism of the wear
particle formation and growth were studied. The results showed
that the final formation for wear particle usually went through
the following stages; The unclear wear particle formation stage
characterized by metal plastic flowing of wear surface and
dominated by cellular substructure cracking process of the
plastic flowing layer; The new born nuclear wear particle growth
stage through debris mutual transfer at the interfaces; The
plowing growth stage of the wear particles which have achieved
their critical size of mutual transfer growth; The second
plowing growth stage of the cracked accumulating layer of wear
particle. It was the processes of the wear particle formation
and growth that predominated the wear behavior.
Key words:
