“…This result is in agreement with that found by Kim et al. 13 reporting that the friction coefficient and the wear rate decreased with increasing surface hardness. Table 4 shows similar results obtained when sliding speed or normal load are increased.…”

“…It is clear that increasing the hardening depth for quenched specimens leads to a decrease in the hardness and an increase in the value of the friction coefficient. This result is in agreement with that found by Kim et al 13 reporting that the friction coefficient and the wear rate decreased with increasing surface hardness. Table 4 shows similar results obtained when sliding speed or normal load are increased.…”

“…Indeed, increasing normal load leads to a decrease in the friction coefficient. This result is in agreement with some studies 13,14 but it is in disagreement with other ones. 15,16 Increasing sliding speed (oscillation frequency) leads to a reduction in the value of the friction coefficient.…”

Tribological behaviour of induction hardened ISO 42CrMo4 low alloy steel was evaluated under unlubricated sliding conditions. The effect of hardening depth and test conditions on the friction and wear properties was investigated. The tribological tests were carried out on a reciprocating tribometer. Cylinder-on-flat contact configuration was adopted. The results showed that varying the hardened depth, normal load or sliding speed influences the friction coefficient, the friction energy, the wear volume and the wear coefficient. It was found, also, that a change in the wear behaviour occurs when a critical value of normal load is exceeded.

“…Microstructures indicated an impressive distinction between the two steels, medium carbon steel contained a mixture of martensite and pearlite in the hardened layer, while low alloy steel exhibited only martensite [9]. An attempt was also made on the example of SUP9 (AISI 5160) to examine the percentage of martensite after induction hardening through tempering [10]. Results concluded that increasing tempering temperature caused a decrease in the percentage of martensite.…”

The research work focused on microstructural changes that occurred in DIN 42CrMo 4 alloy during the induction hardening process with the emphasis on its corrosion and microhardness variations. In this strategy, experiments were performed on the gradually increasing values of induction heating power and time to observe the response of the studied alloy. The optical and scanning electron microscopy was used to examine the microstructures of the processed alloy. Mechanical performance of the induction hardened alloy was characterized using microhardness examination. It was found that the percentage of martensite phase fraction increased with induction heating powers i.e., of 10, 14, 18, and 22 kW. Similar trend was observed for extended induction heating time from 3 to 9 s. A characteristic transformation in martensitic morphology was also observed due to change in processing parameters, which created a significant effect on the corrosion performance and hardness value of the studied alloy. Hardness of the alloy progressively increases with the rise of induction heating power and time and stabilizes at higher input values of induction parameters due to complete execution of martensitic structure. On the characterization of the electrochemical properties, the study revealed that martensitic morphology played dramatic role in the corrosion performance of the alloy. it was found that lath martensitic structure offered greater corrosion resistance compared to coarse martensite with a trivial change in hardness value. Thus, utilization of proper induction parameters needs to be applied for the properties to be optimum.

The main problem occurring during the laser hardening of tools is the lack of continuity and diversity of surface layer properties as a result of the use of many parallel hardening paths. As a consequence, there may be a forgiven or under-hardened area between successive paths. The paper presents the original method of laser hardening of tools, especially bending, using a laser beam splitter. Such a hardening method enables simultaneous heating and tempering of the tool corner and the surfaces adjoining it at the desired width in one pass with the same parameters. As a consequence, the hardened layer is uniform on the surface of the corner and adjacent surfaces, i.e. without forgiven or unhardened areas. The use of this method requires equipping the hardening laser head with a divider, whose task is to distribute the laser beam to separate parts of the beam with adjustable width by means of appropriately placed mirrors. The new method of hardening not only eliminates the problem of so-called hardening marks created as a result of laser hardening, which directly affects the quality, durability and durability of the tool, but is also much more efficient and also beneficial for economic reasons.
