This paper describes the friction properties of cluster diamond/glassy carbon (CD/GC) composites and graphite cluster diamond/glassy carbon (GCD/GC) composites as self-lubricating materials. CDs and GCDs in the shape of superfine particles are intended as solid lubricants. Friction tests were performed on several friction surfaces by varying sliding velocity and load. Testing was carried out in three friction environments (i.e., ambient air, mineral oil and distilled water). The results of these tests revealed that the friction behavior of CD/GC and GCD/GC composites is mainly influenced by both load and CD (or GCD) content in the composites. Their friction coefficients decreased as the load decreased under low load and low sliding velocity in ambient air. In addition, little influence of the friction environments was observed in the friction properties. Consequently, CD/GC and GCD/GC composites are promising as self-lubricating materials, particularly under low-load conditions.
