The process is widely used to convert oxides to sulfides but is also related to corrosion and surface modification.
This conversion is a step in the preparation of catalysts for hydrodesulfurization wherein alumina impregnated with molybdate salts are converted to molybdenum disulfide by the action of hydrogen sulfide.
[4] The process of liquid sulfidation has also been used in the manufacturing of diamond-like carbon films.
These films are generally used to coat surfaces to reduce the wear due to friction.
The inclusion of sulfidation in the process has been shown to reduce the friction coefficient of the diamond-like carbon film.
