摘要：

Experimental evidence is presented in support of the hypothesis that the main factor determining the flow of physical processes on the interface of a sliding solid-state contact carrying a similar to 0.1-1 MA/cm(2) current is the sausage-type MHD pinch instability. It leads to the appearance and explosive destruction of tightening (quasi) liquid constrictions connecting the contact surfaces, so that under magnetic-suspension conditions the sliding of the latter relative to one another is virtually contact-free on the greater portion of their area.
