Abstract
The friction behavior of SiO2/GCr 15 in dry air and lubricated with distilled water, 1-butanol, 1-decanol and octanoic acid was investigated by using SRV ball-on-disk test rig and a Kyowa DF·PM one-way reciprocating friction tester. The reactivity between the lubricants and SiO2 surface was simulated by differential scanning calorimetry. As the results, the order of the friction coefficient under oscillating condition can be ranked as dry air>distilled water>1-butanol>1-decanol≈octanoic acid, and that under one-way reciprocating condition can be ranked as distilled water>1-butanol>1-decanol>dry air≈octanoic acid. The order of the reactivity between the lubricants and SiO2 surface is distilled water>1-butanol>1-decanol>octanoic acid. Thus the higher the reactivity between the lubricants and SiO2 surface is, the higher the friction coefficient will be. The characteristics of the tribochemical reaction film play an important role in governing the friction behavior of SiO2 ceramic.
