Tooling materials science| Summary: | Using the method of hydrostatic weighing, the value of the porosity of compacts formed by the action of pressure of 8 GPa at room temperature on diamond grinding powders of different grain sizes without coating and with coating of titanium on the surface of diamond grains was obtained. It is shown that an increase in the average grain size from 112 to 450 μm reduces the porosity of the formed compact by almost 2 times, the application of a titanium coating leads to a further decrease in the porosity of the compacts. As the grain size decreases, the effect of the coating on increasing the degree of compaction increases due to the increase in the contribution of particle slippage to compactions. |
