We work with, rather than against nature by using a tool coating that produces its own lubricious oxide when the tool tip reaches a certain temperature. Lubricious materials such as MoS2 have limited temperature stability in oxidizing environments and are generally too weak to incorporate inside coatings designed for cutting metals. This target of this project is to fabricate a multicomponent, multifunctional coating. This coating will have high enough strength to persist to high temperature, excellent toughness to resist cracking and delaminating, low wear and when oxidized will produce lubricious oxide optimized friction.
