N2 - Conventional lubricants used as a binder in silver tungsten carbide powder CW0330 for the fabrication of silver tungsten contacts has, unfortunately, been linked/identified as a cause for visual defects in the product that include cracking and peeling. In turn, this led to an unsatisfactory fallout quantity. This study was performed to investigate the effects of substituting the current lubricant with high green strength lubricant to improve the quality of green parts during production. To achieve this, a comprehensive assessment and characterization of powder characteristics, flow property, green strength, and mechanical properties of sintered and infiltrated parts, as well as a visual defect inspection was performed on parts made with the high green strength lubricant and the results compared to previously collected data on conventionally made parts. This paper presents the results that include cost benefits in terms of labor and materials.
