Reciprocating pin-on-flat screening wear tests on EPD discs acting against pure Al2O3 pins

The task of the EC-JRC-IHCP was to evaluate the tribological behaviour of FGM disks performing screening wear tests on a 2-stations "reciprocating pin-on-flat" (RPOF) machine. Alumina pins were employed as counterparts. Preliminary studies were carried out using "Biolox forte™" discs and pins.

Since there is no standard or guideline, which describes RPOF tests on ceramic-ceramic couples (due to the difficulty to avoid edge contact and the risk of pin spallation) these first results allowed to build up a comparison base for the evaluation of the FGM performances. Moreover, they led to the design of a special sample holder that was able to grant a flat contact between pins and disks.

Through laser profilometer and the gravimetric wear measurements, the effectiveness of the pin holder has been proved and the tribological behaviour of the FGM disks has been assessed to be equivalent to that of the reference material (Biolox forte (TM)).
