Abstract
Strips of amorphous metal containing embedded particulate matter and method for making it. Strips of amorphous metal containing embedded particles of abrasive material are useful for working the surfaces of solid articles by abrasion for forming or surface improvement. The method of making such strips involves forcing molten metal of a glass-forming alloy containing admixed particulate matter onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body.
Claims6
The method of forming a continuous strip of amorphous metal containing embedded particulate matter, which comprises:
- (a) moving a chill body in a longitudinal direction at a constant predetermined velocity within the range of from about 100 to 2000 meters per minute past the orifice of a slotted nozzle defined by a pair of generally parallel lips located proximate to said surface such that the gap between the lips and said surface is from about 0.03 to about 1 millimeter, said orifice being arranged generally perpendicular to the direction of movement of the surface of said chill body;
- and (b) forcing a stream of molten metal containing dispersed particulate matter through the orifice of the nozzle into contact with the surface of the moving chill body to permit the metal to solidify thereon to form a continuous strip containing embedded particulate matter.
