    摘要: To form a coating film having an excellent wear-resistant property in a temperature range from low temperature to high temperature a coating-film forming method includes a metal-powder producing step of producing a metal powder containing an element exhibiting a lubricating property when oxidized; an oxidizing step of oxidizing the metal powder so that an amount of oxygen contained in the metal powder is within 6 weight % to 14 weight %; and a coating-film forming step of forming a coating film on a material subject to a treatment, the coating film having such a composition that an area where an oxygen content is 3 weight % or less and an area where an oxygen content is 8 weight % or more are distributed in a unit area of the coating film when the metal powder is in a melted state or a semi-melted state, and an oxygen content of the entire coating film after the metal powder is melted or semi-melted being within 5 weight % to 9 weight %.

    摘要: A wire electric discharge machine which applies a high frequency voltage between poles, i.e., a wire electrode (401) and a work (405) as the other electrode disposed facing the wire electrode (401) at a predetermined distance therefrom so as to generate intermittent discharge and machine the work. The machine comprises a DC voltage application unit (407) for applying DC voltage between the poles and a low frequency component detection circuit (408) for detecting the low frequency component from the voltage between the poles. The state between the poles is monitored according to the output of the low frequency component detection circuit (408), and the axial feed speed is adjusted according to the state between the poles.
