The aim of this research was to establish influence of Ti-enriched powder mixtures on structure and microhardness level of protective layers based on Ni-Cr-Si-B-alloy, produced with non-vacuum electron beam cladding technology. The fabricated protective layers possessed the complex structure, consisting of matrix phase (γ-(Ni, Fe)) combined with hard phases such as Fe2B, CrB and TiC. Addition of titanium with boron in amount of 15 wt. % leads to significant increasing of microhardness level. In this case, level of microhardness increases up to 700 HV.

“…Titanium alloys are prone to contact grasp during friction, regardless of the type and system of doping, as a result, to significant wear and mechanical damage to the contact surfaces. To improve tribotechnical properties of the parts made of titanium alloys, they typically use the same technologies for treating rubbing surfaces as for other metals: thermochemical treatment, electroplating, sputtering, laser and electric-spark surface doping, etc [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Analysis of studies in recent years, leads to the conclusion that traditional methods of increasing the wear resistance of products made of titanium and its alloys are ineffective.…”

“…Recently, a lot of studies have been devoted to improving the tribotechnical properties of titanium alloys by the formation of composite coatings on their surface (TMC -titanium matrix composites) using laser and electron beam technologies [6][7][8][9][10][11][12][13][14]. Particles of carbides, borides, and silicides of metals act as hardening components in these materials.…”

Abstract. In this study structure and tribotechnical properties of cp-titanium after non-vacuum electron beam cladding of powder mixture containing boron carbide were investigated. Structural investigations were carried out using optical and scanning electron microscopy and X-ray analysis. The thickness of cladded layers was 1.3…2.5 mm. The beam moving speed was not influence the phase composition of coatings. The main phases of the surface layers were α-titanium (αʹ-titanium), titanium carbide TiC and titanium boride TiB. It was determined that the average value of microhardness of the samples formed with the speed 25 mm/s was three times higher in comparison with substrate metal. A decrease in the beam moving speed led to an increase in the heat input per unit area and was accompanied by a reduction in the coating microhardness. To evaluate the wear resistance, friction test of the obtained materials against fixed abrasive particles was performed. The maximum relative wear resistance was exhibited by the coatings after cladding of 20 wt. % boron carbide and 30 wt. % titanium with the beam moving speed of 25 mm/s. Their wear resistance was 1.53 times higher as compared to cp-titanium.
