One of the ongoing needs in the materials industry is to facilitate significant production cost saving due to energy usage. One way to do this is to use the thermal energy generally emitted during heat treatment to facilitate additive reactions with the material surface. This has been successfully done by formulating specific lubricity additives into on a oil or aqueous quenching media. When the material is heated and subsequently quenched, the lubricity additive will then react with the surface providing substantial improvements in lubricity. This process is called: “coat forming”. The objective of this paper is to provide an overview of coat forming reactions, additives, and subsequent application performance.
