El presente trabajo tuvo como objetivo la determinación de los valores de densidad aparente, de tasa de flujo y de tamaño de los granos del polvo utilizado en la fabricación de insertos P30S por la industria nacional. Se aplicaron los procedimientos para el control de la densidad aparente y la tasa de flujo (según las norma ASTM B 212-13 y ASTM B213-13 respectivamente) así como el tamaño promedio del grano. Las técnicas utilizadas fueron mediante la aplicación del embudo de Hall (que se fabricó para este propósito) y la microscopía óptica. Los valores obtenidos para la densidad aparente, la tasa de flujo así como el tamaño promedio de grano para el polvo P30S, tuvieron correspondencia con esta designación. Los resultados de las mediciones de densidad y dureza de los insertos fabricados fueron contrastados.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In the current context of industrial development, the use of cemented carbide occupies an important place in the production of inserts for cutting tools. The objective of this work is to determine the values of apparent density, flow rate and size of the powder grains used in the manufacture of P30S inserts by the national industry. The procedures for the control of bulk density and flow rate (according to ASTM B 212-13 and ASTM B213-13 respectively) as well as average grain size were applied. The techniques used were through the application of the Hall funnel (which was manufactured for this purpose) and optical microscopy. The values obtained for the apparent density, the flow rate as well as the average grain size for the P30S powder, corresponded to this designation. The results of the density and hardness measurements of the manufactured inserts were contrasted.]]></p></abstract>
