Growth kinetics and mechanical characterization of boride layers formed on β-type Ti-45Nb alloy

Effects of boron concentration on the microstructure, mechanical and tribological properties of powder-pack borided AISI 4140 steel

“…Pack boriding methods present the simplest experimental setup, compared to the other boriding methods, but higher temperatures and longer treatment times are required [14]. Pack boriding has been recently studied in the boriding of titanium-based alloys [14][15][16][17][18][19], steel alloys [6-8, 10, 20-26], cobalt-base alloys [9,[27][28][29][30][31], and nickel-base alloys [32][33][34], and is usually performed using commercial powder mixtures, however, the pack boriding of steel and iron with different powder compositions was previously investigated [2,10,17,19,26,35,36]. The borided layers in carbon and alloyed steels usually have the Fe 2 B single-phase or a two-phase morphology: FeB and Fe 2 B.…”

Boriding behaviour of titanium alloys with different crystalline structures

“…According to the available literature, various biomedical grade α [7,8,10], α + β [9,11] and β -type [12] Ti and its alloys have been borided and their microstructural and mechanical properties have been investigated. However, in those studies, boriding techniques, process parameters and boriding agents are different from each other which make it so diffıcult to compare the effect of the crystalline structure as well as chemical composition on boride layer development.…”
