Abstract
1. Способ лазерного плавления с использованием абляционного покрытия, содержащий последовательные шаги, на которых:определяют поверхностную область расплавляемого вещества, на которой необходимо произвести плавление;наносят на упомянутую определенную поверхностную область слой абляционного материала;осуществляют облучение лазерным пучком упомянутый слой абляционного материала до расплавления вещества и полного удаления абляционного материала,при этом мощность излучения лазера, режим облучения и толщину абляционного слоя выбирают в зависимости от значения коэффициента поглощения излучения расплавляемого вещества при переходе его в жидкую фазу.2. Способ по п.1, отличающийся тем, что при осуществлении нанесения слоя абляционного материала на поверхностную область расплавляемого вещества характерный размер участка с абляционным покрытием выбирают не меньше диаметра лазерного пучка.3. Способ по п.1, отличающийся тем, что дополнительно наносят новые порции абляционного материала на облучаемый участок в процессе облучения при удалении облучаемого абляционного участка до наступления плавления упомянутого слоя расплавляемого вещества.4. Способ по п.1, отличающийся тем, что лазерный пучок при облучении расплавляемого вещества дополнительно фокусируют на участке с абляционным покрытием.1. A laser melting method using an ablative coating, comprising successive steps in which: determining the surface region of the molten substance to be melted; applying a layer of ablative material to said specific surface region; irradiating said layer of ablative material with a laser beam and complete removal of the ablation material, while the laser radiation power, the irradiation mode and the thickness of the ablation layer are selected m depending on the absorption coefficient of the melt material at its transition to the liquid fazu.2. The method according to claim 1, characterized in that when applying a layer of ablative material to the surface region of the molten substance, the characteristic size of the ablative coated area is chosen not less than the diameter of the laser beam. The method according to claim 1, characterized in that additional portions of the ablative material are additionally applied to the irradiated area during the irradiation process when the irradiated ablative area is removed before the melting of said layer of the molten substance occurs. The method according to claim 1, characterized in that the laser beam during irradiation of the molten substance is additionally focused on the ablative coating area.
