    • A method to filter macro particles in a cathodic arc physical vapor deposition (PVD) in vacuum is described, said method comprising the step of evaporating a material from a solid source (1) by means of application of the arc on the source, forming a plasma comprising electrons, micro particles (vapor) and ions of evaporated material, together with macro particles larger in size than the micro particles and ions. The arc is moved on the source at a speed V cs (superficial speed) at which the electrons, the micro particles and the ions of material evaporated at a point P 2 deviate, from a path towards a substrate (2) to be coated facing the source, the macro particles formed at a point P 1 previously passed over by the arc, so as to self-clean the plasma of the macro particles and allow condensation of only the cleaned plasma on the substrate.
    • 描述了在真空中过滤阴极电弧物理气相沉积(PVD)中的宏粒子的方法,所述方法包括通过在源上施加电弧从固体源(1)蒸发材料的步骤,形成 包含电子的等离子体,微粒(蒸气)和蒸发材料的离子,以及大小比微粒子和离子大的宏粒子。 电弧在源处以在点P2偏离的材料的电子,微粒和材料离子偏离的速度Vcs(表观速度)移动到待涂覆的基底(2)的面向源 ,在预先通过电弧的点P1处形成的宏观颗粒,以便自我清洁大颗粒的等离子体,并允许仅将清洁的等离子体冷凝在基板上。
