This work was aimed at studying the tribological properties of nanolamellar tungsten and molybdenum disulfides produced from nanosized W and Mo nanopowders by self‐propagating high‐temperature synthesis. The prepared WS 2 and MoS 2 powders were examined by scanning electron microscopy (SEM), X‐ray diffraction (XRD), and differential thermal analysis (DTA). For tribological tests, oil‐based lubricants added with nanolamellar tungsten and molybdenum disulfides were prepared. The tribological tests show that the friction coefficient of the nanolamellar powders is lower than that of commercial powder ( μ min = 0.024 and 0.064, resp.). It is also found that the oil‐based lubricants with nanolamellar disulfide additives display higher antifriction and antiwear properties compared to commercial powder.
