The wear resistance of MoS2 in lubricating applications can be increased by doping MoS2 with chromium. Microindentation experiments on nanopillars of Cr-doped MoS2 found that the yield strength increased from an average of 821 MPa for pure MoS2 (0 at. % Cr) to 1017 MPa for 50 at. % Cr. The increase in yield strength is accompanied by a change in the failure mode of the material. While the pure MoS2 nanopillar fails through a plastic bending mechanism, brittle fracture modes become apparent as the material is loaded with increasing amounts of dopant.
