Изобретение относитс к области нанесени покрытий испарением в вакууме, конкретнее к устройству испарителей, примен е1«ы в вакуумных установках, например конвейерных , дл нанесени покрытий на подложки .The invention relates to the field of evaporation coating in vacuum, more specifically to the design of evaporators, used in vacuum installations, such as conveyor systems, for coating substrates.
Изобретение может быть использовано дл получени беспористых защитных покрытий, например, моноокисью кремни , в частности,на отражател х с целью повышени коррозионной стойкости светоотражающего сло .The invention can be used to obtain non-porous protective coatings, for example, silicon monoxide, in particular, on reflectors in order to increase the corrosion resistance of the reflective layer.
Известен испаритель дл нанесени покрытий в вакууме, представл ющий собой проволочный испаритель, свитый в виде конической спирали из тугоплавкого металла 1 ,A vacuum evaporator is known for vacuum coating, which is a wire evaporator twisted into a conical spiral of a refractory metal 1,
Однако этот испаритель не обеспечивает получени беспористого покрыти , вследствие выброса макроскопических частиц, пробивающих получающуюс на подложке пленку.However, this evaporator does not provide a non-porous coating, due to the ejection of macroscopic particles, penetrating the film produced on the substrate.
Цель изобретени - повышение качества покрыти .The purpose of the invention is to improve the quality of the coating.
Достигаетс это тем, что у испарител , выполненного в виде конусообразной спирали из тугоплавкого материала , спирали выполнены с переменным шагом, увеличивающимс от основани конуса.This is achieved in that the evaporator, made in the form of a conical spiral of refractory material, spirals are made with variable pitch, increasing from the base of the cone.
На фиг, 1 изображен предложенный испаритель, общий вид; на фиг. 2 приведена вакуумна камера, общий вид, в которой предложенный испаритель использован дл нанесени беспористой защитной пленки на отражающее алюминиевое покрытие.Fig, 1 shows the proposed evaporator, a general view; in fig. 2 shows a vacuum chamber, a general view in which the proposed evaporator is used to apply a non-porous protective film on a reflective aluminum coating.
10 Предлагаемый испаритель .представл ет собой конусную спираль, свитую из проволоки 1 тугоплавкого металла , например молибдена, к концам которой подводитс ток. Шаг навивки10 The proposed evaporator is a tapered helix made of wire 1 of a refractory metal, such as molybdenum, at the ends of which current is applied. Coiling step
15 спирали - переменный и увеличиваетс от основани конуса. В нижней части конуса размещена навеска 2 испар емого материала, например моноокиси кремни ,The helix 15 is variable and increases from the base of the cone. In the lower part of the cone there is a hinge 2 of evaporating material, for example, silicon monoxide,
