Аннотация
Using a PMT-3M microhardness tester, the microhardness values depending on the distance of the spot of measurement from the frontal plane of the sample to its middle part are determined on the transverse sections of samples of binder VST-1210 hardened under various conditions. It is established that the microhardness value of a plastic depends on the conditions of its curing and also on the spot at which the measurement is carried out—the closer the sample core to the spot of measurement, the higher the microhardness value. The performed sclerometric tests have shown that the width of the groove trace also increases from the middle to the frontal plane of the sample.
