Corrosion resistant coatings are engineered to protect industrial metals from early failure, due to corrosion induced degradation. In the previous post, we discussed various types of corrosion affecting metallic structural components. This post concentrates on
Dry film lubricants, which are also referred to as solid lubricants are basically used to reduce friction caused between two or more surfaces. Therefore, they are also referred to as low friction coatings. These solid coatings are used in almost all environments, such as high and low pressures, high and low temperatures, as well as high and low shaft speeds.
Molybdenum Disulfide (MoS2) is widely known for its excellent lubricating properties. It has a low co-efficient of friction. It has the ability to operate in a variety of temperatures up to 600oF. When combined with resigns or binders, molybdenum disulfide can also be very effective in preventing corrosion.
Tungsten Disulfide (WS2) and Molybdenum Disulfide (MoS2) are two of the most popular industrial dry film lubricants. Both are similar in terms of appearance, color, and high chemical durability. Both are dry lubricants, non magnetic, and are compatible with liquids such as paint, oil, fuel, and solvents. They can be applied on almost all surfaces for industrial purposes including iron, steel, plastic, aluminum, and copper. While both come from the same chemical family, there are certain differences that make them unique and thus, suitable for different industrial applications.
