Abstract
Electro-spark deposition process is widely applied in many fields, such as aviation industry, space technology, energy industry, nuclear reactor and medical apparatus and instruments industry due to its low-heat input, little distortion in base, and easy operation. At present time, a lot of investigations have been done and a lot of results obtained, but there are still a lot of things to be done in the theoretical investigation. For this reason, the forming principle of spot and the adhesion of electrode and the interface behavior have been investigated in this article. When WC electrode was used to deposit TC1 substrate, the adhesion of electrode, which affects the transferring process, was investigated and analyzed. Adhesion, which often produces a thin layer of mixture on the surface of the WC electrode, in the adhesion layer metallurgy reaction occurs and TiC new phase forms.
