“…Despite this, various material handling equipment (drill bits) and machinery parts (gears, crankshafts, train wheels, etc.) are in great demand to fulfill the need for high hardness and high toughness [17,18]. As a result, several researchers have concentrated on improving mechanical characteristics [19] and tribo properties [20,21].…”

The goal of this study is to increase the impact toughness of the borided steel without much compromising the surface microhardness. An optimization technique known as Response Surface Methodology was employed to achieve the goal of this work. The pack borided specimens at optimized conditions were analyzed in terms of microstructure, microhardness, XRD, and Impact toughness and compared with borided specimens treated for 950°C for 180minutes. The poly-phase iron borides zone, transition zone, and base metal were all evident. In the iron borides zone, the microhardness was 1745HV, then 345HV in the transition zone, and lastly 245HV in the matrix area. The XRD technique was used to identify the growth of Fe 2 B and FeB phases. The impact toughness was 44.182 J when the specimens treated at optimized conditions.

“…Another important factor is the change of geometries and loss of mass on agricultural tools causing a reduction in service life; for this reason, boriding can significantly contribute to reducing the wear and abrasion on these tools [4].Boriding by dehydrated paste is a thermochemical hardening process that can be used on tools or workpieces to prolong the life of the tool [5,6]. Research shows that the FeB/Fe2B or Fe2B coatings generated can be used in sectors for agricultural, marine and aerospace [7,8,9]. This study uses a plow disc with chemical composition (weight) of C-0.62% Mn-0.90% Si-0.17%, S-0.035 %, P-0.25%, Ni-0.25%, Cr-0.025%, Cu 0.025%.…”
