Assessing the Effectiveness of Solid Lubricants

Resumo

The effectiveness of a proposed solid lubricant is investigated, on the basis of the abrasive cutting coefficients. Its dependence on the grinding conditions, the characteristics of the boron-nitride wheel, and the alloying of high-speed steel is determined. The lubricant reduces the abrasive cutting coefficient by about 40–50%. A method is proposed for measuring the frictional coefficient. The benefits of lubricant application are assessed. The utility of the abrasive cutting coefficient in estimating the effectiveness of solid lubricant is confirmed.
