A large scale application of sulfidation is the conversion of molybdenum oxides to the corresponding sulfides. This conversion is a step in the preparation of catalysts for

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

ions in a material or molecule. The process is widely used to convert oxides to sulfides but is also related to corrosion and surface modification.
