Processing method for corroding titanium or titanium alloy by burning and exploding under electric spark induction effect

Abstract

The invention relates to a processing method for corroding titanium or a titanium alloy by burning and exploding under the electric spark induction effect, which is characterized in that a gas which can generate vigorous exothermic oxidation and burning and exploding effects with a titanium or titanium alloy materal to be processed is introduced in a processing area intermittently in the conventional process for processing the titanium or titanium alloy under the electric spark induction effect so that the titanium or titanium alloy of which the surface is activated under the electric spark induction effect and the introduced gas are subjected to burning and exploding reactions and a new activated layer can be exposed, and the process is carried out repeatedly so that the surfaces of titanium or titanium alloy substrate materials can be corroded rapidly and continuously in large quantities. Compared with the conventional method for corroding the titanium or titanium alloy under the electric spark induction effect, the invention can improve the material corroding rate by dozens of times or even hundreds of times. The invention can be used for processing through the relative motion of small-scale equipment on a large-scale structural component, can solve the problems on the size, the rigidity and the like of a large-scale structural component processing machine tool and has the advantages of high efficiency, low loss, low cost, safety and no pollution.
