    摘要： By heating the conductive layer (1) by Joule heat generated in the vicinity of the crack (2) a pressure stress leading to at least partial closing of the crack (2) is produced, without the melting of the conductive layer (1). Joule heat in the vicinity of the crack (2) is produced non-homogeneously, which causes a non-homogeneous heat field in the vicinity of the crack (2) and by the root of the crack (21) and thereby generates pressure stresses leading to the closing of the crack (2). The density of the electric current in the conductive layer (1) is between 5.10 3 to 40.10 4 A.m -2 , preferably between 1.10 4 to 25.10 4 A.m -2 . The density of the electric current in the conductive layer (1) by the crack's (2) root (21) is between 1.10 11 A.m -2 to 1.10 13 A.m -2 , preferably more than 1.10 12 A.m -2 . The electric voltage in the conductive layer (1) is 4 to 220 V, preferably 6 to 180 V. The process of treatment runs regularly in the set interval or based on diagnostics of the presence of the crack (2) in the conductive layer (1). Electric current can be generated by the source (3) which is a permanent part of the device or the system with the element (4) so that the autonomously run treatment phase is ensured. The method and the device can be preferably used in transport technology, for example, cars, electric cars, aviation and cosmonautics.
