“…The mechanical properties of the fabricated metal matrix composite specimens were subjected to tensile and mechanical testing [27]. Significant research has already been available on the mechanical properties of pristine bronze [36]. Very few reports were available on the mechanical properties of the TiB 2 fused and Y 2 O 3 fused bronze.…”

The present work is intended to fabricate titanium diboride (TiB2) and yttrium oxide (Y2O3) fused bronze metal matrix composite by stir casting technique to achieve effective mechanical and corrosion properties. TiB2- Y2O3 nanocomposite powders were synthesized using the mechanical milling synthesis technique. Spectroscopic analyses like Powder X-Ray Diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope (SEM) were used to characterize the synthesized nanopowders. The XRD data revealed the average crystalline size of 110±5 nanometres with a hexagonal and cubic phase structure of TiB2 and Y2O3. The fundamental modes and other functional groups of the nanocomposite were analyzed using the FTIR analysis. The SEM images revealed the irregular morphological structures of the composite powders. The bronze metal matrix composite is fabricated by varying the weight percentage of TiB2-Y2O3 nanocomposite as 2%, 4%, and 6 wt.% with bronze alloy via stir casting technique. XRD graphs revealed the formation of metal matrix composite and the FESEM graphs revealed the porous morphology of the composite. The mechanical performance of the composite was analyzed by using the tensile, compression, and hardness tests. Specimen with 4% wt.% reinforcement material offered higher mechanical properties with 303 MPa tensile, 810 MPa compression, 141 HRB hardness, and good corrosion resistance. Hence the fabricated TiB2-Y2O3 fused bronze metal matrix composite with good mechanical and corrosion properties can be used for various sea environment applications.

“…Technologies and installations have been developed for cleaning rolled metal strip from technological lubricants, installations for cleaning wire rod with a diameter of 6.5 mm from scale [3][4]. Currently, at various stages of development, installations for surface treatment of various engineering products are being successfully introduced [5][6][7][8][9]. Preliminary studies have been carried out and a project is being developed for cleaning the inner surface of pipes and the threaded surface of couplings before applying dry lubricating coatings or polymer coatings.…”

The material of the product should be considered as an integral concept that combines the substance, the technology of its production, design, technology of its manufacture and processing. The durability of products depends not only on the properties of the material, determined by the manufacturing technology and volumetric hardening, but also to a large extent on the properties of the surface. Its role in ensuring the performance properties of products is constantly increasing, which, along with the widespread use of traditional methods of chemical-thermal treatment, has contributed to the emergence and development of a new direction - surface engineering by methods of energy and physico-chemical effects. The high rate of high-frequency heating (hundreds of degrees per second) causes a shift in phase transformations to higher temperatures. Therefore, the high-frequency quenching temperature should be higher than the quenching temperature of ordinary furnace heating, and the higher the higher the heating rate. The current density across the section of the part is uneven, on the surface it is much higher than in the core. The main amount of heat is released in a thin surface layer. The depth of current penetration into the metal depends on the properties of the heated metal and is inversely proportional to the square root of the current frequency. The higher the current frequency, the thinner the resulting hardened layer. A reliable method of hardening the surface layer can give comparable results only if the quality of the surface is stable, including its cleaning. The surface condition of the part (tool) depends not only on the structure of the base material and all the conditions for its manufacture, but especially on the last operation of its production or processing. Research is being conducted, among other things, within the framework of the AP14869891 project “Increasing the operational life of heavy-loaded railway transport parts using innovative plasma technology”.
