Title: Pretreatment of thermal spraying process
Inventor: KIKUCHI KOJI
IPC: C23C4/02
Filed: 1986-09-10
Abstract: PURPOSE:To enable reproduction of the surface of a work prior to thermal spraying as it is on a thermally sprayed film without necessitating the execution of machining such as shot blasting as in the conventional method, by subjecting the surface of the work to a corona discharge treatment prior to thermal spraying. CONSTITUTION:Metals, resins, plastics, glass, ceramics, etc., are used for the above-mentioned work. Metals and ceramics such as the oxide, nitride, carbide and boride of the metals are used for the thermal spraying material. The surface of the work is subjected to the corona treatment before a known thermal spraying process; for example, metallizing or thermospraying is executed in the combination of the above-mentioned work and the thermal spraying material. The corona discharge treatment can be executed by using any of generally commercially marketed corona dischargers. Since the surface of the work is roughened by such pretreatment, the pretreatment such as grinding is omitted and the need for a post treatment such as grinding after the thermal spraying is eliminated.

Title: Electric discharge machining device
Inventor: SHODA KAZUO
IPC: B23H7/26
Filed: 1989-08-22
Abstract: PURPOSE:To reduce waiting time for electric discharge, and to increase machining speed by properly providing a high-frequency relative vibrational movement between a work and a machining electrode in an electric-discharge waiting time. CONSTITUTION:An electric-discharge waiting time is detected by a detecting means during the period from the time when a voltage has been applied to a machining gap to the time when discharge is started, and in the entire or a part of this detected waiting time, an actuator means 34 is operated by the control of a controlling means 4, so that a required vibrational movement is given to a machining electrode 28 and/or a work 25. In this way, since the value of the electric discharge machining gap changes in accordance with the vibrational movement during the waiting time, such a condition that electric discharge is easily induced is caused so as to be useful for reducing the waiting time. As a result, electric discharge efficiency and also machining speed can be increased.
