Solid Film Lubricants If you look into the various types of lubricants available in the market, one that stands out is the dry variety. They are used in situations where it is not possible to make use of liquid lubricants. Though liquid lubricants possess many qualities that are very attractive, still solid lubricants are used for many reasons. They are more certainly effective at high loads, speeds providing high stability even when there is extreme temperature, radiation and pressure. In very reactive environments, they remain the same, providing lubrication even under such tough situations. Key Features Of Solid Film Lubricants Some of the key points to note about solid lubricants are their thermal and oxidation stability, melting point, crystal structure, hardness etc. When it is sprayed onto a surface, it gives it protection but does not react to the material of that surface. It is best used in high temperatures that are simply not tolerated by liquid lubricants. Here is a look
