摘要 |
A method for making handleable, strong, discrete, metal-clad abrasive pellets comprises the steps of : (a) spraying onto a bed of gas-fluidized abrasive particles a slurry of metallic powder, a binding agent, and a volatile solvent until substantially all the abrasive particles are coated with at least about 20 wt-% of said metallic powder; (b) recovering said metal powder coated abrasive particles; and (c) heating said recovered coated particles under conditions to form a sintered continuous metal coating enveloping said abrasive particles. Another aspect of the invention comprises a method for making saw blade segments from metal-clad abrasive particles. Preferably, the weight percent of abrasive in each pellet is from about 1 weight percent to about 10 weight percent and the metal coating weight percent ranges from about 99 weight percent to about 90 weight percent. Pellets devoid of abrasive particles; i.e., "dummy" pellets can be included in the mold cavity in order to regulate the concentration of abrasive particles in the saw blade segment. |
