Organomolybdenum Compounds in Surface Engines Protection

The minimum coefficient of friction for pure MoS2 is significantly lower than that for MoS2 xOx, and the peak in the coefficient of friction curve occurs for relatively low concentrations of oxygen in the film. The friction rises rapidly for 

Both original additives are gradually consumed due to oxidation since they act as antioxidants (Korcek at al., 1996). 

This exchange leads first to the formation of the mixed products and, in the second step, full ligand exchange takes place to produce molybdenum dialkyldithiophosphate (Mo(ddp)2) and zinc dialkyldithiocarbamate (Zn(dtc)2). The equilibrium in this reaction favors Mo(dtc)2 and Zn(ddp)2 formation, and the 

In the XANES technique, it is essential to compare spectra of films with those of different model compounds in which the local chemical environments of the phosphorus and the sulfur are known (Brown et al., 1992 Fuller et al., 1998). 

Tribochemically generated tribofilm - sulfur characterization. The effect of the concentration of a MoDTC on tribofilm formation using the Plint reciprocating wear ring machine on a 52100 steel coupon was investigated.
