1. Reuse possible
Condition:
Geometrie of the groove is as new. The overlay inside the groove is intact.
The dark points are predominantly embedded oil coke particles (Fig. 2).
Assessment:
The ratio between the overlay and the aluminium alloy ridges is 75 % / 25 %.
Reuse possible!
Condition:
The overlay in the grooves has worn through uniformly by about 0,005 mm.
The aluminium alloy ridges show no sign of wear. The dark points are predominantly
embedded oil coke particles (Fig. 3).
Assessment:
As a result of overlay wear, the aluminium alloy ridges appear slightly wider.
