摘要

Atmosphere control during ctebiading of powder Injection molded (PIM) parts is an important parameter to consider. Experimental results have shown that a stagnant atmosphere containing volatiles evolved during debinding can cause slumping of the green samples. Removal of volatiles from the sample zone aids debinding and can reduce cycle times and improve sample quality. Eesidual carbon and oxygen can be controlled during debinding by adjusting the atmosphere composition. This paper presents the results of PIM 70 vol percent spherical copper powder and 30 vol percent binder. Debinding atmospheres were altered to determine the effect of debinding on the green body and the sintered sample.
