“…For austenite steels clamping force increase results in the increase of the facial micro roughness, and ultrasonic power has no significant influence. These results correlate with those of ultrasonic smoothing of titanic alloys workpieces [18] and prove possibility of the method application for enhancing utilization qualities of the details and machine nods made of non-ferrous and ferrous metals and alloys. Suggested statistical models of roughness dependence on regime modes for two types of materials, allow determining rational operational conditions during ultrasonic smoothing.…”

Fatigue, corroding and tribological properties of machine parts are mostly determined by surface quality formed during finishing operations. One of the most effective ways to form the required surface is by ultrasonic smoothing. The article presents experimental results of ultrasonic surface smoothing for workpieces of two types of steels 17Х18N9Т and 20Х1М1F1ТR. The experiments were conducted on the turning lathe with the experimental ultrasonic technological complex. The variables were workpiece rotational speed, feeding speed, clamping force and ultrasonic power treatment. D-optimal plan of Hartley-Kono was used during the experiment. Dispersion-regressive analysis of the experimental data revealed the relation between the surface roughness and processing regime modes. Feeding lowering decreases the surface roughness for both steels. To decrease the surface roughness of 20Х1М1F1ТR steel it is necessary to increase power of ultrasonic treatment simultaneously with clamping force decrease. For steel 17Х18N9Т clamping force results in surface roughness lowering that is why ultrasonic power is not significant. Partial correlation coefficient analysis revealed that micro profile height for steel 20Х1М1F1ТR is determined by feeding speed. For austenitic steel 17Х18N9Т feeding speed and clamping force are equally important factors. During the experiments the surface roughness decreased from 1.5 mkm to 0,1-0,2 mkm with ultrasonic treatment, that is more than 10 times.

“…The ultrasonic treatment mode (frequency and amplitude of vibrations, shape and radius of the indenter, speed of the main motion and feed rate, static force) determines the quality parameters of the surface layer (roughness, waviness, microhardness, residual stresses, hardening depth, dislocation density) that affect operational properties of machine parts (strength, wear resistance, contact stiffness, fatigue resistance, corrosion resistance, tightness of joints, friction coefficient, etc.) [9][10][11][12].…”

The aim of this study was to study the properties of 1201 aluminum alloy after ultrasonic treatment and their evolution during subsequent ion implantation using the monotectic Cu-Pb alloy as the cathode material of the implant. It is shown that during ultrasonic treatment the surface layer of aluminum alloy 1201 undergoes significant changes. A nanocrystalline structure with a grain size of less than 200 microns is formed in it. Ultrasonic treatment of the surface of the target from alloy 1201 before implantation leads to a decrease in the depth of penetration of ions to 160–180 nm and the appearance of amorphization in the implanted layer.
