Title: Method for peeling low-pressure thermally sprayed film
Inventor: YOSHIMOTO NORIFUMI
IPC: C23F1/00
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To selectively peel only the films without using a mechanical method by putting the films into a state to allow peeling by a peeling liquid, then peeling the films by using the peeling liquid. SOLUTION: This method is more specifically a peeling method after operation for a specified time of the low-pressure thermally sprayed films formed on heat resistant members, such as gas turbine blades. Namely, aluminum is diffused into the films to reform the surface layers thereof so that the films are put into the state of allowing the peeling by the peeling liquid. The diffusion of the aluminum is executed by an aluminum coating diffusion treatment method or aluminum coating diffusion treatment method. The heat resistant members subjected to the reforming of the film surfaces are then immersed into the peeling liquid to selectively peel only the films. As a result, the mechanical method, such as shot blasting, is not used and, therefore, the damage of the base material surfaces does not arise and the recycling of the members is made possible.

Title: Removing method of alkaline earth metal from alkaline earth metal-containing magnesium alloy
Inventor: NAKAMURA TADAYOSHI
IPC: C22C1/02
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To selectively remove only an alkaline earth metal by dissolving an alkaline earth metal-containing Mg alloy with a flux for Mg alloy. SOLUTION: The alkaline earth metal added in the Al alloy, when melted in the presence of flux for Mg alloy reacts with a metallic chloride contained in the flux and halogenated and removed. The other components such as Zn, Mg contained in the alloy except the alkaline earth metal are not changed even in the presence of the flux. That is, the alkaline earth metal is selectively removed. This is caused by that the alkaline earth metal reacts with the metallic chloride in the flux to form a chloride more thermodynamically stable than the metallic chloride and is fetched in the flux and is removed from the molten alloy. In this case, as the flux, any one for dissolving, for refining or of the mixture of them is used.
