The friction coefficient, wear rate, and wear coefficient of the aluminum metal surface were measured\nat room temperature (300 K) with a pin-on-disk machine at a fixed load of 196.2 N. Two different testing\nconfigurations were adopted: (1) aluminum pin vs. Helix oil-on-steel disk (AHS) and (2) aluminum pin vs. 10%\nPolytron plus 90% helix oil-on-steel disk (APS). In the AHS configuration, the wear of the aluminum surface was\nfound to be approximately 70 m; however, in the APS configuration the wear dropped to 20 m, revealing a\nmarked decrement of one-third of the wear of aluminum. The volume wear rate of the metal in the unaided Helix\noil was estimated to be 1.28Ã?â??10ââ?¬â??3 mm3/min. The additive minimized the volume wear rate of the aluminum metal\nby orders of magnitude to 6.08Ã?â??10ââ?¬â??5 mm3/min. Similarly, the wear coefficient of the aluminum pin, calculated in\nthe AHS configuration, rendered a value of 1.27Ã?â??10ââ?¬â??10 m2/N. In the APS configuration, the same parameter was\n4.22Ã?â??10ââ?¬â??11 m2/N, that is to say, an order of magnitude lower than the preceding value. The observed coefficient of\nfriction for aluminum is 0.012 in Helix oil and falls to a remarkably lower value of 0.004 through the Polytron\nadditive. The experimental findings demonstrate that Polytron additive substantially lessens the wear of the\naluminum surface; in effect, the wear coefficient and the wear rate decline linearly. This singularity may be linked\nto the ability of Polytron to impregnate the crystal structure of the metal due to its ionic character and the consequent\nadherence to the metallic surface as a hard surface layer.
