Resumen
En este trabajo se construyó una máquina denominada “rueda de caucho – arena seca” de acuerdo a la norma ASTM G 65, con el fin de determinar el desgaste abrasivo de diferentes materiales. El daño por desgaste que conlleva la pérdida de material es tal vez la situación más sencilla de describir cuantitativamente. Los ejemplos más comunes incluyen desgaste abrasivo en el manejo de materiales sólidos, como ocurre en la industria minera. La pérdida por desgaste puede ser determinada mediante medición de masa, midiendo el cambio, ya sea en masa o cambio dimensional. La norma de desgaste abrasivo como la ASTM G 65 es utilizada ampliamente por la industria para ayudar en la selección de materiales para el servicio de desgaste abrasivo. Las opciones de cargas y las distancias de deslizamiento se detallan en los métodos de ensayo A B C D y E descritos en esta norma. La medición del cambio de masa por este método de ensayo suele ser rápida y barata y los costos del material pueden ser bajos. Además la superposición de soldadura, recubrimientos, cerámica, materiales compuestos y muchos otros tipos de materiales pueden ser estudiados con este método.
This work was built a machine called “dry sand/rubber wheel” according to the standard ASTM G 65, in order to determine the abrasive wear of diferent materials. The damage by attrition entailing the loss of material is perhaps the simplest to describe quantitatively. The most common examples include abrasive wear in the management of solid materials, as in the mining industry. The loss by attrition can de determined by measuring mass by measuring the change, either mass or dimensional change. The rule of abrasive wear as ASTM G 65, it is widely used by industry to assist in the selection of materials for the service of abrasive wear. The options for the loads and distances sliding detailed in the A B C D and E test methods described in this standard. The measurements of mass change of this test method is usually quick and cheap, and the costs of materials can below. Besides the overlay welding materials, coatings, ceramics, composite materials, and many other types of materials can be studied by this methods.
