very fine abrasives in the hibricant, the polishing<br />
wear may become excessive.<br />
Polishing wear can be prevented by using less<br />
chemically active additives .. Asan alternative to<br />
ulfus -phosphorous additives, anti-scuff lubricants<br />
are available with dispersions of potassium borate(13)<br />
which deposit EP films without chemically<br />
reacting w:ith. the metal, Removing the abrasives<br />
in the lubriean; by using fine filtration or frequent<br />
oilchanges<br />
is helpful.<br />
Methods of Preventing<br />
Polishing Wear<br />
1. Use less chemically active anti-scuff additives,<br />
such as borate.<br />
2. Remove abrasives from the lubricant by using<br />
fine filtration or frequent oil changes.<br />
scuffing during the critical running-in period.<br />
The basic mechanism of scuffing is not<br />
understood clearly, but by general agreement, it<br />
is believed to be caused by intense frictional<br />
heating generated by the combination of high<br />
sliding velocity and intense surface pressure,<br />
