Some metallic materials like W, Al, Ni, and Ti of high purity are used for EDD, which could be taken from available wires providers.
Variants of EDD on electrical discharge machines The coatings of various materials by EDD are used in many fields like automotive industry and turbine blades fabrication due to high temperature and wear resistance of coated materials [4], medical industry to improve antibacterial properties of the coated material [5]; in many areas, where is required a high wear resistance obtained by a certain texture of the materials [6] etc.
Applications that use the deposited metallic materials like W and its combinations (presented above), Al, Ti, and Ni are reported.
The materials allocated to the elements of the technological system of EDD Boundary conditions.

Das et al. [17] used the data in Shida et al. [18] to propose polynomial relationships for various materials to accurately relate the yield strength and the material temperature.
This assumption was found to hold for most of the engineering materials such as steels.
