The reciprocating tests on a bulk silver alloy were also complemented by 20-cycle repetitive unidirectional scratch tests with a diamond indenter to (i) help understanding of how wear proceeds in the more complex, higher cycle reciprocating test (ii) help determine whether nano-scratch tests can be designed more efficiently on rough surfaces. When it was stable friction, the maximum value of the temperature of frictional contact point was [19] (4) T max = μ P V 4 a (λ 1 + λ 2) where λ 1 and λ 2 was the thermal conductivity of friction material and counterpart material, a was a dimension-dependent constant, and V was friction velocity.

The initial decrease in friction in the reciprocating tests on 316L stainless steel, reducing ploughing friction through smoothing of surface asperities, was also observed in 10-cycle nano-scratch tests at 30 mN with a 3.7 μm radius diamond [9] (data converted to friction coefficient in Fig. 9) and in 1 N tests on copper with a 100 μm radius . Molybdenum disulphide (MoS2) based solid lubricant mixtures containing zirconia and graphite were prepared in the laboratory and coated on steel specimens.
