“…Increasing PPB temperature up to 1073 K resulted in the increase of the peaks of TiB 2 phase and reduction in the α-Ti peak. The XRD analysis to be consistent with the results of previous studies 3,9,11,18,29 verified that both titanium borides were formed even at low temperature such as 700°C. Since all boriding temperatures applied were below the α→β transformation temperature (890°C), the substrate still had α-titanium structure.…”

In the present study, commercial pure titanium was successfully plasma paste borided using borax paste at a temperature of 700, 750 and 800°C for 3, 5 and 7 h. The X-ray diffraction and scanning electron microscopy techniques revealed the presence of both TiB 2 top-layer and TiB whiskers sub-layer. The formation rates of the TiB 2 layer and TiB whiskers were found to have a parabolic character at all applied process temperatures. Based on the present Ti borides growth data, correspondent diffusion temperature and time, an analytical diffusion model was used to estimate boron diffusion coefficients and activation energies of the boride phases in a binary multiphase Ti-B system. Depending on the temperature and layer thickness, the activation energies of boron in TiB 2 and TiB phases were determined to be 137.55 ± 0.5 and 55.21 ± 0.5 kJ mol −1 , respectively. These values of boron activation energies for pure titanium were compared to the literature data.

“…The characterization of borided titanium and its alloys by using various boriding processes has been evaluated by a number of investigators [11][12][13][14][15]. However, no reference could be cited in the literature concerning titanium boride coatings, on Ti alloys obtained in a plasma paste process.…”

“…These compounds are a group of materials with superior properties such as chemical stability, high hardness, high melting point, good thermal conductivity, and low electrical resistivity [9][10]. Titanium boride layers can be obtained by boriding of titanium and its alloys through diffusion of boron at 700-1100 o C for various methods of boriding, such as boriding in a fluidized bed reactor [11], laser boriding [12], pack boriding [13], electrochemical boriding [14] and plasma assisted boriding [15]. Plasma boriding has some advantages when compared to conventional boriding processes.…”

“…However, their relatively poor tribological properties, such as high friction coefficient and low hardness, are barriers to their use in applications that require high surface hardness and wear resistance [1][2][3][4][5][6]. Surface modification techniques, including chemical vapor deposition (CVD) [7][8][9][10][11], physical vapor deposition (PVD) [12][13][14][15][16], laser and plasma surface treatment [17][18][19][20], thermal oxidation [21][22][23][24][25][26], sol-gel processing [27,28] and nitriding [29][30][31][32], have been applied to improve the tribological and wear properties of Ti alloys.…”
