Kedu ihe bụ Electro-Spark Deposition?
Ngwọta electro-spark, nke a makwaara dị ka Electro-discharge machining (EDM), bụ usoro nrụpụta pụrụ iche nke gụnyere iji mpụta eletrik na-emepụta ma gbanwee elu akụkụ igwe.

Mgbe a tọhapụrụ ike capacitor, ihe dị ugbu a na-emepụta arc plasma dị elu n'etiti ọnụ electrode na metal alloy workpiece.Ọnọdụ okpomọkụ a dị elu dị n'etiti 8000 na 25000 Celsius.Plasma arc ionizes anode na-ebufe ngwa ngwa ihe wụrụ awụ na workpiece.
A na-ebufe anode ionizing a na mkpụrụ site na mkpirisi mkpirisi.Arc na-ekpo ọkụ dị elu nwere ihe ndị bụ anode, iyi ọkụ (jet na-ekpo ọkụ), na plasma mepụtara site na mwepu nke gas na atom ndị na-arụ ọrụ nke nitrogen, oxygen, na carbon.Ọtụtụ n'ime okpomọkụ na-ebu site thermal jet na plasma.
