“…The studies have shown that highly effective abrasive granules of different shapes (but with the same binding and abrasive components) under the influence of the same vibrations move with different speeds, both in different zones and medium, and, respectively, with different stability; they have different mobility and volume expansion. In the studied granules, the velocity spread is 21-37%, which coincides with the results of [15][16][17][18][19][20].…”

The article presents the results of experimental studies of the influence of polymer abrasive granules shape on the surface roughness formation and metal removal during vibrational finishing and hardening treatment (VFHT). As is known, surface roughness and the amount of metal removal are affected by a number of factors: binder material, material and granularity of the abrasive, technological lubricant-coolant medium (LCM) type, loading mass, initial roughness, etc. Processing was carried out for 120 min on a UVG-4x10 vibrating machine, with a working chamber volume of 10 dm3. Metal removal Q (grams) and surface roughness Ra (μm) were measured using an AD-200 analytical balance and an SJ-210 profilometer. The results presented show that polymer abrasive granules have high cutting ability, the intensity of which depends on the shape of the granules.

Preliminary experimental studies of the possibility of increasing the microhardness of the surface layer of the material by the method of wave thermodeformational hardening on the example of austenitic steel class 12X18H10T are carried out. Comparative studies on the hardening of the material with and without heating were also carried out. The possibility of a significant increase in the maximum microhardness in the range from 25 to 50% at a depth of up to 0.6 mm, depending on the hardening mode, in comparison with the deformation treatment in the “cold” state is established. The area of technological modes providing the maximum increase of microhardness in the surface layer is revealed, in particular, the temperature of the treated surface should be in the range from 200°C to 400°C. At the same time, the achieved microhardness values exceed the initial one by 1.8…2.2 times, depending on the processing modes. It is also found that when choosing rational processing modes, the combined wave thermal strain hardening can significantly increase the hardening depth to 4.2 mm of the surface layer compared to the initial state. To establish the possibility of improving the performance of combined processing requires additional research.
