Choice of atmosphere during deposition includes vacuum, inert atmosphere, and oxidizing, carburizing and boriding atmospheres.
The anode or the cathode current distributor is made of a metal which is treated by either nitriding, boriding or carbiding the metal in order to make the metal oxide growth resistant.
The friction surfaces (R) are after-treated by way of carboring, carbonitriding, case hardening, gas nitriding, oxide nitriding, gas nitro carburizing, plasma nitriding, plasma oxidizing, borating, plasma carborating or plasma borating.
The invention relates to a method for producing a boride layer on a surface by means of plasma boronizing in which a gas medium containing a boron dispenser medium is fed to a reactor (10), and a glow discharge is generated in said reactor (10).
Boronizing with the paste according to the invention can be applied for steel and cast iron, for Ni and its alloys, and for Co and its alloys.
In addition, the paste is self-protective, which means that there is no need for protecting or reducing atmosphere during boronizing, and this makes the process easy and cheap.
