METHOD OF METAL CORD TREATMENT Russian patent published in 2009 - IPC C23C26/00 B21C23/22 B32B5/02 B60C9/00 C23F17/00 C21D9/52 

FIELD: metallurgy.

SUBSTANCE: invention refers to methods of metal cord treatment by means of high frequency induction discharges under conditions of dynamic vacuum. The method consists in effecting surface of metal cord with low temperature plasma created in a flow of plasma generating gas. The process is carried out in the discharge chamber by means of supply of voltage to electrodes connected to a high frequency generator at 13.3-26.6 Pa pressure in the discharge chamber and 0.6-1.1 A current strength on the anode of the generator. Effect with low temperature plasma lasts for 15-30 sec. Plasma generating gas consists of mixture of 70 % argon and 30 % hydrogen; consumption of the mixture is 0.06-0.12 g/sec.

EFFECT: improved adhesion of rubber to metal cord, increased automobile tire life.
