Abstract
Official abstract text for this publication.
Employing a compact molded from powder of metal or the like as an electrode 11 , generating pulsed discharges between the electrode 11 and a treating portion Wa of work W in working oil L as a mixture with powder of semiconductor or conductor mixed therein, using discharge energy thereof for locally fusing surface regions of the treating portion Wa of work W, showering molten pieces of electrode material or reactants of the electrode material onto the treating portion Wa of work W, forming a covering film C on the treating portion Wa of work W.
First claim
Opening claim text (preview).
What is claimed is: 1. A coating block comprising a sintered compact comprising a powder of ZrO 2 mixed with at least one electrode material, wherein the electrode material is a powder of a metal, a content of the ZrO 2 powder is from 3% to 15% by weight to the electrode material, and the compact further comprises a powder of a chromium-containing cobalt alloy. 2. The coating block of claim 1 , wherein the content of the ZrO 2 powder is 10% by weight to the electrode material. 3. The coating block of claim 1 , wherein a powder particle size of the ZrO 2 powder is from 5 to 10 μm. 4. The coating block of claim 1 , wherein the sintered compact is a sintered green pellet. 5. The coating block of claim 1 , wherein the coating block is capable of generating a discharge energy between the coating block and a treating portion of work in a working oil. 6. The coating block of claim 1 , wherein the content of the ZrO 2 powder is from 5% to 15% by weight to the electrode material. 7. The coating block of claim 1 , wherein the content of the ZrO 2 powder is from 5% to 10% by weight to the electrode material.
