Abstract
A carbonaceous material is fabricated by a mixture of carbon powder and a binder. 10% by weight or more and 60% by weight or less of metal powder to the fabricated carbonaceous material is mixed. The mixed carbonaceous material and metal powder are pressurized and formed. A brush base material is fabricated by burning of the pressurized and formed carbonaceous material and metal powder. The fabricated brush base material is impregnated with oil. An impregnation rate of the oil to the mixed carbonaceous material and metal powder may be 0.5% by weight or more, for example.
Claims11
A metal-carbonaceous brush including:
- a carbonaceous material made of a plurality of carbonaceous particles;
- metal mixed with the carbonaceous material;
- and
- oil with which the carbonaceous material is impregnated, wherein
- a ratio of the metal mixed with the carbonaceous material to the carbonaceous material is 10% by weight or more and 60% by weight or less.
A method of manufacturing a metal-carbonaceous brush including the steps of:
- fabricating a carbonaceous material by mixing carbon powder and a binder;
- mixing 10% by weight or more and 60% by weight or less of metal to the fabricated carbonaceous material;
- forming the mixed carbonaceous material and metal;
- thermally processing the formed carbonaceous material and metal;
- and
- impregnating the thermally processed carbonaceous material with oil.
