  • Method of treating ceramics for use as tips in saws and other tools or other structures
    Publication number: 20020034652
    Abstract: A method of processing a ceramic body, such as a saw tip so that the ceramic body can be bonded to a substrate, such as a saw blade. The ceramic body is desirably a cermet, and it is first cleaned, preferably using sodium hydroxide. After this, the ceramic body is etched by an acid, after which a metallic coating is applied to the bonding surface either by electrolysis by an electroless process. Then the ceramic body is either brazed or welded to the substrate.
    Type: Application

  • Method of treating a ceramic body to form a wettable surface
    Patent number: 5624626
    Abstract: The present invention provides a method for treating a ceramic body to provide a wettable surface on the ceramic body. According to the present invention, a ceramic body is immersed in an alkaline hydroxide solution. The ceramic body is connected to form the anode and a suitable metal is connected to form the cathode of an electrolytic cell. A difference in electrical potential is imposed across the electrolytic cell which is sufficient to remove portions of the ceramic body to provide a pitted surface on the ceramic body which is wettable.
