So as to provide a target arrangement with improved mounting and dismounting ability, the target arrangement comprises a plate along a plane (E) which has a border (7) defined by a first wedge surface (5 u ) angled to the addressed general plane (E) and a second wedge surface (5 1 ) which is substantially planar as well and angled with respect to the generic plane (E). The two wedge surfaces mutually convert in a direction along the addressed plane (E) and from a more central area of the plate outwardly.

A de-coating method capable of recycling a tool or a mechanical part coated with an inorganic material such as PCD (poly-crystalline diamond) is provided. According to the de-coating method, a substrate to be subjected to de-coating (coated body) is less likely to have a dead area during ion irradiation, a brittle phase is less likely to be formed in the substrate (metal body) in terms of temperature, and de-coating can be performed at an economical speed. The problems can be solved by the de-coating method including: exposing the coated body in which a coating made of an inorganic material is formed on a surface of the metal body to ion flows to peel off the coating from the metal body, wherein the coated body is placed at an ion flow-concentrated portion where two or more ion flows overlap each other, and is exposed to the ion flows without addition of a positive or negative bias to the coated body. As gases for use in generating ions from plasma, oxygen and CF 4 that promote de-coating through a chemical reaction are preferably used in addition to Ar that performs de-coating under the physical action of ion collision and stabilizes plasma.

The invention relates to a cathodic arc evaporation device comprising an evaporation chamber (2), at least one cathode (7) and at least one anode (13, 13A). The cathode (7) comprises a body of a material which is evaporated by the arc on an evaporation surface (71). According to the invention, an insert (100, 200) is disposed on the aforementioned evaporation surface (71), said insert comprising an electrically conductive part (101, 201) which projects out in relation to the evaporation surface (71), in order to establish a point for the easy formation of a spark. The inventive device also comprises a gas inlet (102, 202) which is aligned with the above-mentioned electrically-conductive part (101, 201) and which is used to inject a gas into the chamber (2) at said electrically conductive part, in order to facilitate the formation of a spark. The invention also relates to an arc ignition method.

An arc source macroparticle filter (1) includes a circular cathode (2) for emitting particles and an extended cylindrical anode (3) adjacent to and co-axial with the cathode for accelerating the emitted particles. Torroids (4) generate a magnetic field to define a continuous non-linear plasma duct (5) for directing charged particles and separating therefrom undesirable larger particles. The duct is minimally non-linear to permit high rates of charged particle transmission. Arc source filter (1) allows heating and/or the deposition of a variety of surface coatings to a workpiece (8). Also claimed is a method of producing vanadium dioxide.

摘要:
The present invention relates to a method and apparatus for producing electric arc plasma and for use thereof for depositing coatings on a substrate. Electric arc separated plasma is produced using electric arc discharge on a cold cathode by passing it through a curvilinear plasmaguide. Said plasma is created within the curvilinear plasmaguide and electric current is put through it in a longitudinal direction forming length-uniform magnetic field whereby allowing a high-quality coating to be deposited on the substrate using sputtering.
