Title: Method for increasing surface hardness of metallic material using electric discharge phenomenon and metallic material increased in surface hardness by the same method
Inventor: SAWAGUCHI KAZUO
IPC: C21D1/38
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To form a high-hardness hardened layer by mixing a high hardness substance into the inner part of the surface of a metallic material and allowing it to penetrate into the inner part without forming films on the surface of the metallic material and to provide a metallic material free from peeling and having sufficient hardness and wear resistance. SOLUTION: A metallic material 1 as a work and an electrode 2 are disposed in a manner to be opposed to each other in hydrocarbon type working oil 4. The electrode side of a pulse power source 3 is connected positively and the metallic material side is connected negatively to perform electrical discharge machining. The electrode 2 is eluted by means of high temperature at electrical discharge machining and the surface of the metallic material 1 as a work is half melted. The eluted electrode chemically combines with the carbon component resultant from the decomposition of the working oil. The resultant high hardness component is allowed to penetrate into the half-melted surface of the metallic material to form a high-hardness hardened layer 7 composed of the high hardness component which penetrates in the inner part of the metallic material.  Further, the high hardness component 5 is also accumulated on the surface of the metallic material. Subsequently, the high hardness component 5 accumulated on the surface of the metallic material 1 is removed.

Abstract: PURPOSE:To measure the film thickness of every layer, by sticking foil pieces corresponding to the thickness of layers of a function separation type photoreceptor at specific positions and forming the layers by vapor deposition when laminating the layers, and then removing the foil pieces and measuring the film thickness by formed recesses repeatedly. CONSTITUTION:A charge transfer layer 21 is vapor-deposited on a photosensitive layer base and then a small piece 4 such as an adhesive tape is stuck to part of an end part of the photoreceptor 2 which is not used as a photosensitive layer. Then, a charge generation layer 22 is vapor-deposited thereupon, and then the adhesive tape is peeled off to form a recess 5 in the charge generation layer 22 where the vapor-deposition is not performed, so the probe of a surface roughness gauge is scanned on the part to read a difference (h) in level corresponding to the thickness of the charge generation layer. Further, the thickness of a surface layer laminated thereupon is also adjusted by the same operation procedure. Consequently, the thickness of each layer is measured and adjusted accurately, so the photoreceptor with necessary characteristics is obtained.

Abstract: PURPOSE:To prevent the release of a casting mold gas to the atm. by embedding a pipe which has many vent holes on the surface and is connected with an air releasing device at the terminal into the casting mold and operating the air releasing device during or after pouring until a molten metal solidifies. CONSTITUTION:The pipe 5 which has the many vent holes 6 on the surface and is connected by flexible joints 7 is embedded in the drag 2 of the casting mold and the opening end 8 of the pipe 5 is connected to the outside air releasing device.
