| description | This paper reported the first results of the investigation of the use of borax (di sodium tetraborate decahydrate) ® Scharlau , as a lubricant powder metallurgy. Two groups of samples were prepared by adding in the first group, the commercial lubricant zinc stearate and in the second group the powder borax in concentrations of 0.5 % by weight, using as matrix powder metallurgy Ancor Steel ® 1000 iron. Ancor Steel 1000 was mixed with lubricants in a rotational homogenizer for 30 minutes; the sampleswere compacted at 700 MPa in a uniaxial press of 15 tons. DSC-TGA analysis of the mixture with borax was realized. The specimens were sintered in a plasma reactor at 1000 for 30 minutes, with a combined atmosphere of hydrogen and argon. Microhardness and density of the sintered samples was haracterized. XRD analysis was realized to detect possible compounds formation by interaction of borax. This paper shows that borax can be used as a lubricant in powder metallurgy. |

En este trabajo se reportan los primeros resultados de la investigación del uso del Bórax (di Sodio tetraborato decahidrato) Scharlau ®, como lubricante pulvimetalúrgico. Se prepararon dos grupos de probetas, adicionando en el primer grupo el lubricante comercial Estearato de Zinc y en el segundo grupo el polvo bórax en concentraciones de 0.5% en peso, usando como matriz el hierro pulvimetalúrgico Ancor Steel 1000®. El polvo pulvimetalúrgico se mezcló con los lubricantes en un homogenizador rotacional durante 30 min, se compactaron las probetas a 700 Mpa en una prensa uniaxial de 15 toneladas. Se realizó un análisis DSC -TGA a la mezcla con bórax. Las probetas se sinterizaron en un reactor de plasma a 1000ºC durante 30 minutos, con una atmosfera combinada de Hidrogeno y Argón. Se caracterizó la densidad y la microdureza de las probetas sinterizadas. Se realizó un análisis de DRX para detectar formación de posibles compuestos por la interacción del bórax. Este trabajo muestra que el Bórax puede ser utilizado como lubricante en la pulvimetalurgia.
