Influence of diode laser heat treatment and wear conditions on the fretting wear behavior of a mold steel

Comparison of Effects of Laser, Ultrasonic, and Combined Laser-Ultrasonic Hardening Treatments on Surface Properties of AISI 1045 Steel Parts

“…Conversely, reducing the hardening depth and increasing the hardening width in the carbon steels occurs with increasing the carbon content due to the reduction of thermal conductivity [18]. The effect of LHT on the hardening depth [19,20], structure [21,22], phase transformation [23], grain size [13], hardness distribution [24], and residual stress [25] of hypoeutectoid steels were widely studied.…”

Effect of Heat‐Treatment and NiB–TiO2 Composite Coating on the Tribological Performance of AISI P20 Steel

“…These processes typically involve heating the surface of AISI P20 steel or depositing a thin film onto the mold surface. Laser processing methods, [2,[20][21][22][23][24][25] plasma/ gas nitriding, [22][23][24][25][26] electrical discharge machining, [27][28][29] laminar plasma jet, [14] boronizing, [30][31][32] carburization, [31,33] and physical vapor deposition (PVD) coating, [5,6,9,34] are the most common techniques used to minimize, as much as possible, the failure at mold surface made of prehardened AISI P20 steel.…”
