Abstract

Это изобретение относится к области надреза материи с использованием облака упорядоченной плазмы, особенно к облакам упорядоченной плазмы, формируемым и удерживаемым волнами электромагнитной энергии, передаваемым генератором высокочастотных сигналов, который согласован по полному сопротивлению, частоте и выходной мощности с частицами атомов, составляющими облако упорядоченной плазмы, которое окутывает верхушку активизированного режущего передающего электрода. Предложен способ резки материалов с использованием плазмы, состоящий из следующих этапов: применение электронной системы, в состав которой входят генератор импульсов высокочастотного диапазона и усилитель мощности, получение высокочастотной энергии, подача упомянутой высокочастотной энергии в верхушку активного режущего передающего электрода, формирование электромагнитного поля снаружи упомянутой верхушки активного режущего передающего электрода, создание облака плазмы, которое окутывает упомянутую верхушку активного режущего передающего электрода путем возбуждения частиц атомов вдоль границы раздела между упомянутой верхушкой активного режущего передающего электрода и обрабатываемой материей без применения впрыска ионизируемого газа в область, расположенную вокруг упомянутой верхушки активного режущего передающего электрода, поддержание облака плазмы путем высокоэффективной передачи энергии от электромагнитной волны к упомянутым частицам атомов, расположенным вдоль границы раздела между упомянутой поверхностью верхушки активного режущего передающего электрода и упомянутой материей, которая должна надрезаться,This invention relates to the area of incision of matter using an ordered plasma cloud, especially to the clouds of an ordered plasma formed and held by electromagnetic energy waves transmitted by a generator of high-frequency signals, which is matched in terms of impedance, frequency and output power with the particles of the atoms of the cloud of an ordered plasma which envelops the tip of the activated cutting transmitter electrode. A method of cutting materials using plasma is proposed, consisting of the following steps: using an electronic system consisting of a high-frequency pulse generator and a power amplifier, obtaining high-frequency energy, supplying said high-frequency energy to the top of an active cutting transmitting electrode, generating an electromagnetic field outside said top active cutting transmitter electrode, creating a plasma cloud that envelops the said tip of the active cutting electrode. Transmitting electrode by exciting particles of atoms along the interface between said tip of active cutting transmitter electrode and treated matter without using injection of ionizable gas into the area around said tip of active cutting transmitter electrode, maintaining plasma cloud by highly efficient transfer of energy from electromagnetic wave to said particles of atoms located along the interface between said surface of the active cutting tip and transmitting of its electrode and the said matter, which must be incised,
