ION IMPLANTATION METHOD OF SURFACES OF PARTS FROM STRUCTURAL STEEL

FIELD: machine building.SUBSTANCE: method involves implantation into the steel surface of copper ions, and then lead ions. Prior to the implantation, the part surface shall be treated with a laser beam that is focused at the spot in the form of a circle with specific emission density of 260-800 W/mm...

Zusammenfassung:	FIELD: machine building.SUBSTANCE: method involves implantation into the steel surface of copper ions, and then lead ions. Prior to the implantation, the part surface shall be treated with a laser beam that is focused at the spot in the form of a circle with specific emission density of 260-800 W/mm; after that, the spot is moved along the treated surface at the speed of 25-40 mm/s.EFFECT: increasing wear resistance and reducing friction coefficient of the part surface at sliding friction.3 dwg, 1 tbl Изобретение относится к области машиностроения, а именно к способам ионной имплантации поверхности деталей из конструкционных сталей. Технический результат - повышение износостойкости и снижение коэффициента трения поверхности детали при трении скольжении. Способ включает имплантацию в поверхность стали ионов меди, а затем ионов свинца. При этом перед имплантацией поверхность детали обрабатывают лазерным лучом, который фокусируют в пятно формой круга с удельной плотностью излучения 260-800 Вт/мм, после чего пятно перемещают по обрабатываемой поверхности со скоростью 25-40 мм/с. 3 ил., 1 табл.
