Film Formation by Transition Metal Dichalcogenides on Metal Substrates.

摘要

The adhesion of MoS2 powder burnished onto Ti, Cu, Cr, Al, stainless steel (types 304L and 347), and Au substrates has been studied. Scanning electron micrographs reveal substantial differences in the degree of film formation by MoS2 on these metals. The observed differences in surface coverage correlate well with the relative strengths of the substrate metal-sulfur bonds as estimated from the atomization energies of the relevant bulk compounds as calculated from thermodynamic data.
