Molybdenum and chromium, co-deposition of aluminum salts can be generated chromium molybdenum red pigment, molybdenum ion and the metal surface of iron ions to form insoluble Fe2 (MoO4) 3, so that the metal surface passivation to achieve the effect of rust. Clarification of its color change from light to light red color, with strong coverage, and the bright color, mainly used in paints, plastics, rubber, ink, automotive and marine coatings and other fields. Zinc, calcium and sodium molybdate as a corrosion-resistant paint, because without affecting the environment and human health of lead and a universal concern.
Molybdenum disulfide (MoS2) is a good solid lubricant, in industrial applications play an important role. It has a very low coefficient of friction (0.03-0.06), high yield strength (3.45MPa), can at high temperature (350 ℃) and a variety of ultra-low temperature conditions of use, even under vacuum conditions at 1200 ℃ to work, in particular, mechanical parts in high-speed operation has a very good lubrication. Therefore the steam turbine, gas turbine, metal roll, gear, die, automotive and aerospace equipment widely used.
