“…Thicker FeB layer formation can be attributed to the greater amount of alloying elements present in the substrate. It is known fact that alloying elements tend to retard boron diffusion towards substrate and favors the growth of the FeB rather than Fe 2 B [18,19]. On the other hand, the presence of CrB in the boride layers can be associated with the outward diffusion of chromium atoms (from the substrate to the boride layer) during boriding.…”

“…Studies have shown that FeB and Fe 2 B phases dissolve considerable amounts of chromium and the solubility limit of chromium in Fe 2 B is much lower than in FeB [20,21]. Incorporation of chromium into the FeB and formation of CrB as a interstitial compound provides higher hardness in the boride layer [19]. In accordance with the literature, higher hardness was obtained from the boride layer of the higher chromium (5.19 wt%) containing X40CrMoV5-1 steel (2185 715 HV 0.1 ) than that of the lower chromium (2.52 wt%) containing 31CrMoV9 steel (2000 720 HV 0.1 ).…”

“…Under vacuum, adhesive wear is reported [33,34]. Garcia-Bustos et al performed four-ball tests on borided steel balls contacting each other and reported a strong influence of the load on the friction coefficient in non lubricated conditions, from~0.55 at 49 N to 0.35 at 147 N, suggesting a lubricating effect at high loads [35].…”

Wear mitigation in a sliding couple is challenging if wear has to be minimized on both surfaces. In this paper, ball-on-disk testing is performed on sliding couples where both surfaces (ball and disk) are treated for wear resistance. Studied materials are pack borided H13 tool steel (ASTM A681), pack borided AISI 420 stainless steel (ASTM A276) and plasma sprayed yttria-stabilized zirconia (YSZ). Borided H13 steel exhibits a single phase Fe2B layer, while AISI 420 has a double phase layer, with FeB on the outer surface. Both FeB/Fe2B and FeB/YSZ couples generate three-body abrasion. In the latter case, mass transfer occurs from the ball to the disk as well. Friction coefficient is ~0.6 for the AISI 420/Fe2B and FeB/Fe2B sliding pairs, with less vibration on the latter and wear rates close to 10−3 mm³·(N·m)−1 for both the ball and the disk. In comparison, the FeB/YSZ pair has a friction coefficient of ~0.65, a similar total mass loss, but a much higher wear rate for YSZ than for FeB.

“…Much work has been carried out on the wear resistance of borided steels of various composition, investigated under many different testing conditions [12][13][14][15]. Green et al [14] investigated the erosion mechanisms of low carbon AISI 1050 steel in relation to the carbon content and microstructure.…”

Investigation of the Erosive Wear Resistance of Boronized Ash-Blowing Nozzles

In this study, pack boronizing was applied to ash-blowing nozzles manufactured from AISI 1040 steels using Ekabor II powders as the boronizing source at a temperature of 1273 K for a duration of 8 h. Erosive wear tests of boride ash-blowing nozzles were carried out in ash delivery line of thermal reactor under actual working conditions. It was observed that erosive wear resistance of borided ash-blowing nozzles were increased 3 times as a result of the boronizing process. The improved wear resistance of the borided samples can be explained by increased surface hardness and higher work hardening.
