“…Table VI. Associated Failure Modes and Mechanisms on the Worn Surfaces [12,58] Wear Mode Wear Failure Mechanism Maximum von Mises was found in the interface between the base material and the borided layers, optimal for the gearbox applications. Also, due to the reduction of the wear rate, contact pressures and the cracking as a failure mechanism on the worn surface, the PPBP + DAP provides a major performance for this application.…”

“…In this way, other different failure mechanisms appear, such as material agglomeration, smearing and, in some cases, the formation of a tribofilm due to the effect of the experimental parameters in adhesive wear mode. [58] In Figure 21, the failure mechanisms are more evident for the PPBP-WC ball tribopair. Notice that the presence of plastic deformation on the edge of the wear track is higher, and the other failure mechanism is influenced by the contact pressures and shear stresses during sliding.…”

“…Also, the presence of oxide islands that act as a lubricant and reduce the material loss can be seen, which is attributed to the adhesive and tribochemical wear modes. [23,58] According to Evans, [59] for gearbox applications, it is important to consider the influence of the stresses generated by vibrations, sliding and peak loads. However, the effects generated by lubrication and additives, as well as hydrogen from the environment, also influence this type of component.…”

New results about the influence of a small iron borided layer (~36 lm) obtained by the powder-pack boriding process (PPBP) and diffusion annealing post-process (DAP) were evaluated. Dry sliding wear tests on PPBP, PPBP + DAP and untreated AISI 1018 steel were performed under the pin-on-disc configuration, and balls of Al 2 O 3 and WC were used as a counterpart at different sliding distances. Also, the contact pressures of the layer/substrate system were evaluated using the finite element model with the aid of the ABAQUS software. The results showed that the Al 2 O 3 ball presented the major coupling (ball-disc), and the PPBP + DAP reduces the specific wear rate around ~304 times related to the untreated AISI 1018 steel to 500 m under severe sliding conditions.

“…The wear tracks did not exceed the thickness of the Fe 2 B (for the 1.21B and 4.35B samples) and FeB (for the 8.26B sample) layers. Since borided layers are useful for tribological applications if k < 10 -6 mm 3 /Nm [21], the samples of the three conditions presented mild wear. The 1.21B sample, with the higher wear rate (k=1.3…”

Three different boron amounts were used in this study to control the microstructure, mechanical, and tribological properties of borided cases on AISI 4140 steel. A single Fe2B phase was observed for the lowest boron amount, while both Fe2B and FeB phases were present on the other two boron compositions. The highest surface hardness was observed in the highest boron amount. The scratch tests revealed different cohesive failure mechanisms on the samples, such as arc and chevron tensile cracks, and even chipping was observed for all three-studied boron amounts; it appeared at lower applied loads for the highest boron amount, indicating a likely detachment of the fragile FeB layer. The borided layers presented abrasive wear during the ball-on-flat wear tests. Despite the lower specific wear rate, the surface damage was more severe in the sample with the highest boron amount, due to its brittleness, resulting in lower resistance to surface fatigue.

“…The manufacturing process also plays an important role in realizing the impact of alloy design on steel, such as heat treatment [13,14] and chemical treatment processes [6,[15][16][17]. Products of low carbon high strength offshore steel mainly adopt a thermo-mechanical control process (TMCP), off-line quenching, and tempering processes [6,18].…”

Improving the mechanical performance of low-carbon offshore steel is of great significance in shipbuilding applications. In this paper, a new Cu-Cr microalloyed offshore structural steel (FH36) was developed based on EH36. The microstructure, mechanical properties, and fatigue crack propagation properties of rolled plates of FH36, EH36, and normalizing rolled EH36 plates (EH36N) manufactured by a thermo-mechanical control process (TMCP) were analyzed and compared (to simplify, the two rolled specimens are signified by FH36T and EH36T, respectively). FH36T showed an obvious advantage in elongation with the value of 29%, 52.2% higher than the EH36T plates. The normalizing process led to a relatively lower yield stress (338 MPa), but substantially increased the elongation (33%) and lessened the yield ratio from 0.77 to 0.67. Electron back-scattered diffraction (EBSD) analysis showed that SFs of the deformation texture of FH36T and EH36N along the transverse direction (TD) and normal direction (ND) were much higher than those of the EH36T plate, which enhanced the lateral movement ability in the width and thickness direction, enhancing the ductility. Moreover, FH36 plates showed a better fatigue crack propagation resistance than rolled EH36 plates. The formation of the jagged shape grain boundaries is believed to induce a decrease of effective stress intensity factor during the fatigue crack propagation process.
