Abstract

A method of treating an electrically conductive surface comprises using an electro-sparking process for adding one or more substances to the material of this surface, wherein one or more of the substances to be added are in powder form. By the term "electro-sparking" is meant a plurality of discharges of electric energy of very short duration occurring simultaneously with each other and also in succession between an electrode and the conductive surface to be treated which forms the other electrode, the spark being produced in a medium which may be liquid or if gaseous is at atmospheric pressure. The powder may be suspended in a gas, liquid, or paste, or it may form part of a sparking electrode in the form of a metal graphite compact or it may be in the form of a tube containing the powder. The powder may be one or a combination of high melting point metals such as chromium, tungsten, tantalum, which may also combine chemically with the graphite of the electrode to form a carbide on the surface being treated. The powder may be dispersed in a carbonaceous carrier such as wax, grease or mineral oil. When the work piece is steel, a hard carbide layer may be formed on its surface. Specification 749,486 is referred to.
