摘要 |
A process for deposition of a wear-resistant coating onto a cutting tool made from a carbon-containing material by condensation of a substance by bombardment with ions of a cathode material evaporated in a vacuum chamber by means of an arc discharge, wherein prior to placing the cutting tool into the vacuum chamber it is immersed into a saturated solution of a salt, kept therein for 5 to 10 min and the solvent is evaporated till crystallization of the salt on the cutting tool surface occurs; heating of the cutting tool by ion bombardment is effected first to the temperature of decomposition of the salt crystals, whereafter the arc discharge is switched-off, the cutting tool is kept for 15 to 30 seconds, the arc discharged is re-energized and the heating is continued to the temperature of carbidization of the evaporated cathode material. |
