    Abstract: A welded assembly includes a first object or substrate, an interlayer, and a subsequent layer deposited on the interlayer. The interlayer is an ESD coating deposited on the first object, and the subsequent layer is deposited by ESD on the interlayer. The subsequent layer is made of a different materials from the substrate. Both the interlayer and the subsequent layer are subject to peening. In one case the interlayer has a lower either a lower thermal conductivity or a lower electrical conductivity than the substrate and the subsequent layer. In another example, the subsequent layer has a cermet content of greater than 40 % by wt.

    Abstract: A coating deposition apparatus has first and second charge sources. The first charge source is chargeable to a first voltage potential and the second charge source is chargeable to a second voltage potential. The coating deposition apparatus also has a first output terminal and a deposition substance connected thereto, and a second output terminal for connection to a workpiece. The consumable deposition substance is movable relative to the workpiece. The first charge source is connected between the first and second terminals whereby the first voltage potential is established therebetween. The second charge source is connected between the terminals. The coating deposition apparatus also has discharge control circuitry connected to the first and second charge sources to inhibit discharge of the second charge source through the terminals prior to commencement of discharge of the first charge source through the terminals.

    Abstract: Molybdenum is alloyed into stainless steel surface by electro-spark deposition technique. Shielding gas is used during electro-spark deposition process to minimize the oxidation of materials. Control of electro-spark voltage, frequency, capacitance, time can determine the alloying depth of Molybdenum. The alloyed surface thickness varies from 5 μηι to 80 μπι depending on the electro-spark deposition parameters. The alloyed surface comprises, by weight, 15 to 40% of Molybdenum, 8 to 22% of Cr, 0-15% of other alloy elements and impurities. The molybdenum alloyed stainless steel surface exhibits improvement in micro-hardness, wear resistance, and especially corrosion resistance in sodium chloride solutions. Thus, the present invention would be utilized in marine and handling of brines application, as well as in other applications which better corrosion resistance of stainless steel is desired.

    Abstract: A welding electrode is mounted in a tool holder that is part of a handle apparatus. The handle apparatus has an electrode power connection. The handle apparatus has a housing defining a haft that can be grasped in the hand of an operator. A vibrator is mounted inside the haft. The vibrator includes a force transmitter in the form of a cantilevered beam. The cantilevered beam is electrically conductive and carries power to the tool holder. The tool holder has a handle that permits the welding rod to be rotated about its axis as it wears during deposition of welding rod material on the object work piece.
