Description

:о 11941 Известны различные способы поверхностного упрочнени  деталей, включаю щие, например, нагрев электронным пучком и последующее быстрое охлаждение за счет отвода тепла в основ- s ную массу детали в вакуумных установках . Дл  получени  локального поверхностного упрочнени  металла в труднодоступных местах с малой глубиной О закаленного сло , а именно в несколько дес тков микрон, путем регулировани  плотности энергии и длительности импульса предлагаетс  производить нагрев под поверхностную закалку лучом оптического квантового генератора . При диаметре закаленного п тна 300 мкм твердость поверхности стали У9 измен етс  от 900 кг/мм в центре п тна до 200 кг/мм на его границе. Глубина сло  с твердостью не ниже 600 кг/мм составл ет около 20 мкм. При этом плотность энергии составл гет ДИО Дж/см при длительности импульса 0,5 м/с.: o 11941 Various methods of surface hardening of parts are known, including, for example, heating by an electron beam and subsequent rapid cooling due to heat removal to the bulk of the part in vacuum units. In order to obtain local surface hardening of metal in hard-to-reach places with a shallow depth O of the hardened layer, namely several tens of microns, it is proposed to heat the surface quenching with an optical quantum generator by adjusting the energy density and pulse duration. With a 300 μm quenched spot diameter, the surface hardness of the steel U9 varies from 900 kg / mm in the center of the spot to 200 kg / mm at its boundary. The depth of the layer with a hardness of at least 600 kg / mm is about 20 microns. In this case, the energy density was het DIO J / cm with a pulse duration of 0.5 m / s.
