Claims (1)

Способ поверхностного упрочнения деталей, включающий нагрев поверхности детали электронами до температур, не превышающих температуру плавления, отличающийся тем, что нагрев поверхности детали до температуры закалки осуществляют потоком плазменных электронов, формируемым несамостоятельным сильноточным диффузионным разрядом, и последующее резкое охлаждение проводят в потоке аргона со скоростью, превышающей критическую скорость закалки стали.A method of surface hardening of parts, including heating the surface of the part with electrons to temperatures not exceeding the melting temperature, characterized in that the surface of the part is heated to a quenching temperature by a plasma electron stream formed by a non-independent high-current diffusion discharge, and subsequent sharp cooling is carried out in an argon stream at a rate exceeding the critical rate of steel hardening.
