Abstract
PURPOSE: To obtain the brake disc readily and inexpensively by compacting and pressure-contacting stainless steel powder or the like to the annular disc part of a disc substrate formed by a plate material or lower grade steel, ordinary steel or the like and firing this in a furnace.
CONSTITUTION: A steel plate blank 1 of lower grade steel or ordinary steel such as SP material or the like, of a square shape cut to the specified size is pressed to be formed with a truncated-cone-form bulging part to one side in the central part. Next, an axle insertion hole 5 is pierced at the center of the mounting part 2 and windows 6... in the tapered part 3 by a press machine, at the same instant of which the outside circumferential unnecessary part 7 is cut off. Mixed powder of stainless steel powder, copper powder, etc. is coated in thin-thickness form on the both front and back surfaces and outside circumferential end edges of the annular disc part 4 assuming the pad sliding parts of the resultant disc 8 and the powder is compacted to form a green compact layer 9. This is charged into a brazing furnace to let the copper braze material melt so that the stainless steel particles are bound to the disc part 4.
