Corrosion and wear resistance of borided layers

Formation of boride layers at the Fe–10% Cr alloy–boron interface

“…The microstructure of section V consisted of the FeB phase and, to a lesser extent, the alloy base, while that of section VI was entirely the alloy base. As seen from Table 3, the larger orientation order is characteristic of the inner portions of both boride layers compared to their near-interface portions, in agreement with findings of the other researchers [1,12]. The FeB and Fe 2 B phases dissolve considerable amounts of chromium (Tables 4 and 5).…”

“…This amount of KBF 4 appears to be optimum [1,8]. The mixture was then slightly pressed, and a load of 8.5 g (a lowcarbon steel cylinder) was placed on top.…”

“…of steels, metals and alloys [1][2][3]. Iron borides Fe 2 B and FeB are known to exist in the Fe-B binary system [4][5][6][7].…”

Growth kinetics and abrasive wear resistance of boride layers on Fe–15Cr alloy

“…A Fe–Cr alloy tablet was embedded into a mixture of B powder with 5KBF 4 as an activator. This amount of KBF 4 is considered to be optimum 1,28. The mixture was then slightly pressed, and a load of 8·5 g (a low C steel cylinder) was placed on top.…”

“…Boriding is one of the thermochemical surface treatments often used to improve service characteristics (hardness, mechanical and corrosive wear resistance, etc.) of metals, alloys and steels 1–24. Iron borides FeB and Fe 2 B are known to exist in the Fe–B binary system 25,26.…”
