The combination of diamond-like carbon (DLC) coatings and fluid lubrication is an efficacious method to improve the performance and service life of the friction-pairs working under the severe conditions, but the synergistic effect of DLC coatings and lubricant additives have not been clearly unveiled. The synergistic effect of Cr-doped DLC coatings with different Cr content and the lubricant additives of ZDDP, MoDTC, and T307 on the wear of DLC-coated stainless steel sample was studied, and it was found that the wear resistance of DLC-coated stainless steel sample can be further improve by the combination of DLC coatings and fluid lubrication; doping DLC coatings with Cr at an optimum level is beneficial for the wear resistance of DLC-coated stainless steel sample lubricated by PAO, PAO+ZDDP or PAO + MoDTC, but DLC coatings with a moderate Cr content is harmful to the wear resistance of DLC-coated stainless steel sample lubricated by PAO+T307. The synergistic effect of T307 and undoped DLC coatings or Cr-doped DLC coatings with a Cr content of 23.3 % is the best, while the three studied lubricant additives are harmful for the wear resistance of DLC coatings with a Cr content of 2.4 %.

ABSTRACTDiamond-like carbon films have been prepared by using dual ion beam sputtering deposition under CH++Ne+ bombardment with energies 50–800 eV. The obtained films possess a smooth surface and an amorphous structure containing some sp3 bondings. DLC films bombarded by low energy CH++Ne+ exhibit the relatively high binding energy and electrical resistivity which are approximate to those of diamond. It is believed that a Mo interlayer between AISI 52100 steel substrates and DLC films brings the films good adhesion. This offers promises to DLC films on bearing steel to perform a stable wearing in much lower friction coefficient (<0.1) under large wear loads (30–90N). Experimentally, low wear coefficients and high anti wear numbers obtained prove that the DLC films indeed possess excellent wear resistance. In addition, the speed or the momentum of friction motion was revealed to exert some serious effects upon the wear resistance of DLC films when the wearing was carried out under very high wear load (> 30 N).

AbstractThis article reports on the corrosion and wear resistance of Ni-P and Ni-P-PTFE nanocomposite coatings deposited on mild steel substrates using the electroless plating technique. The coatings were characterized by scanning electron microscopy (SEM), energy dispersive analysis of X-Ray (EDAX), and X-ray diffractometry (XRD). The coatings were smooth and had thicknesses between 7 and 23 µm. They contained Ni, P, and additionally, F, in the case of the Ni-P-PTFE films. A broadening of the Ni peak in XRD was attributed to the amorphous nature and/or fine grain size of the films. Corrosion resistance was measured using immersion and electrochemical polarization tests in 3.5% NaCl solution whereas wear resistance was determined by the pin-on-disc method. Both Ni-P and Ni-P-PTFE coatings exhibited significant improvement in corrosion (in salty media) and wear behavior. Furthermore, the addition of PTFE in the coatings showed improvement in their corrosion resistance as well as a reduction in friction coefficient. Our testing revealed that the coatings’ wore out following the “adhesive type” mechanism.
