Introduction The development of biodegradable materials as an alternative to non-degradable materials continues to gain momentum.
As a rule, these materials are composites based on synthetic and natural fillers, where renewable sources of raw materials act as natural fillers.
Besides, these materials must have acceptable performance properties.
Composite materials are artificially obtained multiphase materials that have the required properties.
Acknowledgments The materials under investigation were studied with the equipment of the common use centers at the Emanuel Institute of Biochemical Physics of the Russian Academy of Sciences and the Plekhanov Russian University of Economics.

Electrical discharge machining is used for all kind of materials, more or less electroconductive, especially because of the non-contact between workpiece and tool, so that it doesn’t matter how hard the material is [1, 2].
Thus, the temperature of small volumes of the electrodes materials increases rapidly, determining processes of material melting or even vaporizing.
In the future, there is the intention to develop experimental researches on other metallic materials, in order to establish also possible correlations between the chemical composition and sizes of surface roughness parameters specific to the surfaces obtained by electrical discharge machining.

Convective boundary condition corresponds to the existence of convection (heating/cooling) at the surface, which assumes that heat conduction at the surface of the material is equal to the heat convection at the surface in the same direction.
