Title:
接触部材の製造方法及び装置
Document Type and Number:
Japanese Patent JP3652706
Kind Code:
B2
Abstract:
A method of producing a contact element having a base body made of material with good electrical conductivity (first material) and a contact layer made of material with a less good electrical conductivity which is resistant to arc erosion (second material), includes impregnating a sinter structure of the contact layer with the material of the base body. The base body and the sinter structure are placed one above the other in a cup-like mold and are heated therein to above the melting temperature of the first material but still below the melting temperature of the second material, so that the first material fuses and penetrates into the sinter structure. The sinter structure may be produced by scattering the second material in powder form onto the first material and initially sintering in a degassing process below the melting temperature of the first material. It is also possible to produce the sinter structure in advance and to place a green body on the base body. A device for carrying out the method includes a cup-like mold formed of steel or stainless steel or a mold formed at least partially from ceramic.
