Chemical vapor deposition (CVD) diamond films are suitable as protective coatings on cutting tools for machining advanced composite materials, owing to their extremely high hardness, favorable wear resistance, low friction coefficient and high thermal conductivity.
In the case of machining the composite materials, the protective effects of the diamond films are mainly provided by the extremely high hardness withstanding the abrasive attack, and low frictional coefficient helping to reduce polymers stick to the tools [7].

Xu at East China University of Science and Technology computed the cooling degree coefficient and heat balance in 1999 [8].
Another example is for the type when the surrounding material has a much higher thermal conductivity than the studied material.
In this case, the surrounding material imposes the boundary temperature.
