В технике микроанализа (например тут http://www.struers.com/en-GB/Knowledge/Grinding-and-polishing#grinding-polishing-troubleshooting ) такие дефекты известны. И описаны как:
Lapping tracks are indentations on the sample surface made by abrasive particles moving freely on a hard surface. These are not scratches, like from a cutting action, but are the distinct tracks of particles tumbling over the surface without removing material.
- If an abrasive particle is not held in a fixed position while the sample is passing over it, it will start rolling. Instead of removing the material, the grain is forced into the sample material, creating deep deformation and only pounding small particles out of the sample surface.
- Lapping tracks can be produced during both grinding and polishing.
- The causes are: wrong disc/cloth surfaces for the actual operation or the wrong force. Also combinations of these faults can cause lapping tracks.
Выглядят они таким образом:
Example: Lapping tracks on Zicalloy, Mag. 200 X.
These are indentations on the sample surface made by abrasive particles moving freely on a hard surface. There are no scratches, like from a cutting action. Instead, there are the distinct tracks of particles tumbling over the surface without removing material. If abrasive particle is not held in a fixed position while the sample is passing over it, it will start rolling. Instead of removing, cuttingm chips of matrial, the grain is forced into the sample material, creating deep deformation, and only pounding small particles out of the sample surface.

Механизм также понятен:
Lapping
In lapping, the abrasive is applied in a suspension on to a hard surface.
In lapping, the abrasive is applied in a suspension on to a hard surface. The particles cannot be pressed into the surface and secured there. They roll and move freely in all directions, hammering small particles out of the specimen surface and introducing deep deformations. The reason is that the free moving abrasive particle is not able to produce a real "chip" of the specimen surface.
The three positions of an abrasive grain passing the specimen surface in a rolling fashion.
Position 1:
The grain enters the specimen surface.
Position 2:
The grain rolls over and hammers a piece of the specimen material out, causing severe deformation in the specimen material.
Position 3:
The grain rolls on without touching the specimen surface. When it passes the specimen again a smaller or bigger piece is hammered out, depending on the shape of the grain.
Вот такая фигня, малята...
