Mathematical models of the surface hardening VT20 and OT4 titanium alloys by electrospark alloying have been developed. These can be used in design technological processes for manufacture blades steam turbines.

The article presents the results of laser alloying process ductile cast iron EN-GJS 350-22 surface with titanium. was conducted on 2 kW high power diode (HPDDL) Rofin Sinar DL02 rectangular focus and uniform density distribution in axis. constant beam processing speed titanium powder feed rate variation. tests produced layers included macrostructure microstructure observations, X-ray diffractio...

In the present study, Ta coatings with a thickness of 1.7 and 4.2 μm were deposited on Ti samples through reactive magnetron sputtering. The are furthermore treated by scanning electron beam in order to form Ti-Ta surface alloy. A change phase composition alloy was observed X-ray diffraction (XRD). microstructure chemical studied via microscopy (SEM) energy-dispersive spectroscopy (EDX). result...

Laser alloying is an effective method to form functional surface layers (coatings) on metallic materials, particularly stainless steels. Unique phase balance, dislocation substructure, and a possibility obtain gradient microstructures after laser slow down the degradation increase wear resistance. In this work, optimal parameters of their effects microstructure properties were investigated for ...
