“…In this way, it will be possible to increase their useful life and increase productivity [36]. In addition, it should be noted that the strength of commercial metal alloys is increasing, which requires harder, stronger and more durable tool steels for their forming or cutting [37]. The hardness of tool steels is typical of quenching martensite and is influenced by the carbides deposited in the martensitic matrix [36].…”

Diamond-like carbon (DLC) coatings are very interesting due to their extraordinary properties; their excellent wear resistance, very low friction coefficient, great hardness, high elastic modulus or biocompatibility can be highlighted, as can their multifunctionality. Because of this, over recent decades they have been widely used in tribological applications, improving the performance and the useful life of machining tools in an effective way. However, these coatings have a disadvantage compared to other coatings deposited by commercially available techniques—their resultant adhesion is worse than that of other techniques and limits their industrial applications. In this work, tribological results of a scratch test, wear resistance and nanoindentation of tetrahedral amorphous carbon (ta-C) and tungsten carbide:carbon (WC:C) DLC coatings deposited by means of novel high-power impulse magnetron sputtering (HiPIMS) technology with positive pulses are reported. The coatings were deposited in three different tools steels: K360, vanadis 4 and vancron. These tools’ steels are very interesting because of their great and wide industrial applicability. Experimental results showed excellent tribological properties, such as resistance to wear or adhesion, in the two types of DLC coatings.

“…However, lead and tin recrystallize rapidly at room temperature after significant deformations so that the working of these metals at room temperature is like hot working. Similarly, the work of tungsten at 1093°C, in the hot work range of the steel, is a cold work because this high melting metal has a recrystallizing temperature higher than this working temperature (Figure 1) [14].…”

“…Work rolls of cold rolling, requiring high surface hardness, good thermal shock resistance, anti-stripping ability, and wear resistance, are usually produced using high carbon and high-alloy forged steel, such as Cr8 [1], D2 cold work tool steel [2], semi-highspeed steel (SHSS) [3], high speed steel (HSS) [4,5], etc. High speed steel has the best service performance among these materials.…”

To improve the comprehensive performance of high speed steel (HSS) cold rolls, the induction hardening processes were analyzed by numerical simulation and experimental research. Firstly, a modified martensitic phase transformation (MMPT) model of the tested steel under stress constraints was established. Then, the MMPT model was fed into DEFORM to simulate the induction quenching processes of working rolls based on an orthogonal test design and the optimal dual frequency of the induction quenching process was obtained. The results indicate that the depth of the roll's hardened layer increases by 32.5% and the axial residual tensile stress also becomes acceptable under the optimized process. This study provides guidance for studying phase transformation laws under stress constraints and the optimization of complex processes in an efficient manner.
