What is Brinneling??
Bruising ,Marking the bearing surface?
Here is the definition of Brinelling...
Brinelling refers to a material surface failure caused by contact stress that exceeds the material limit. This failure is caused by just one application of a load great enough to exceed the material limit. The result is a permanent dent or "brinell" mark.
What we have on my engine is a case of "False Brinelling"...
False brinelling is damage caused by fretting, with or without corrosion, that causes imprints that look similar to brinelling, but are caused by a different mechanism.
The basic cause of false brinelling is that lubricant is pushed out of a loaded region. Without lubricant, wear is increased. It is possible for the resulting wear debris to oxidize and form an abrasive compound which further accelerates wear.
