  • What Is Graphite Lubricant It Still Runs

    One is graphite suspended in a liquid base that will evaporate when the liquid is painted on a surface. When the liquid evaporates it will leave a thin layer of pure graphite to lubricate the surface. Graphite grease is a form of graphite lubricant that is designed to stick to a surface such as when used on an exposed bearing.

Such resistance however is a function both of temperatures and concentration and there are many reagents which can be handled for limited temperature ranges and concentrations. In borderline cases it will be found that there is limited attack generally resulting in some swelling due to absorption.

    There are exceptions to this relationship. The most common exception is grey cast iron which is quite brittle even though it is fairly soft. Its composition of sharp-edged graphite flakes creates stress concentrations that override the ductility of the iron. Temperature Temperature has a significant affect on the ductility of metals.
