“…It could be seen that the highest wear resistance of wallex50 alloy corresponded to a moderate hardness rather than the highest hardness among the tested coatings. It contradicted Archard's law [31]. This result indicated that the hardness was not the only factor to impose the influence on the wear resistance.…”

Co-based alloy cladding layers (wallex50 and wallex55) were synthesised on 316L stainless steel by vacuum cladding. Experimental results showed that wallex50 composed of γ-Co, WC, Co 6 W 6 C, Cr 7 C 3 , in which in situ reinforcement WC phases were homogeneously distributed in the layer, having a clear and stable interface structure. Wallex55 with externally added WC particles was composed of γ-Co, WC, Co 6 W 6 C, Cr 7 C 3 , CrB, CoWB. The average microhardness of wallex50 and wallex55 was 794 ± 29 and 939 ± 24 HV, respectively. Nevertheless, wallex50 showed a better resistance to friction and wear than wallex55, which was not in a cross line with Archard's law. Relative wear resistance of wallex50 was 23.36, which was 1.56 times greater than that of wallex55. The improvement of friction and wear for wallex50 could be due to the fact that the in situ synthesised WC particles increased the friction and wear resistance by the pinning effect of the retained reinforced phase on the Co-based matrix.

“…This indicated that microhardness was not the only factor that affected wear resistance. The improvement of wear resistance could be achieved by proper combination of high microhardness and toughness [44]. As shown in Figure 9e, there were more oxide particles and clear plastic flow and adhesion on the worn surface of 12CrNi2V low alloy steel.…”

To obtain the wear-resistant camshaft with surface rigidity and core toughness and improve the service life of camshaft, wear-resistant Fe-based alloy gradient material was prepared by laser melt deposition. The traditional camshaft was forged by 12CrNi2V. In this paper, four types of wear-resistant Fe-based powders were designed by introducing various content of Cr3C2 and V-rich Fe-based alloy (FeV50) into stainless steel powder. The results showed that the gradient materials formed a satisfactory metallurgical bond. The composition of the phases was mainly composed of α-Fe, Cr23C6, and V2C phases. The increasing of Cr3C2 and FeV50 led to transform V2C into the V8C7. The microstructures were mainly cellular dendrite and intergranular structure. Due to the addition of Cr3C2 and FeV50, the average microhardness and wear resistance of gradient materials were significantly better than that of 12CrNi2V. The sample with 8% V had the highest microhardness of 853 ± 18 HV, which was 2.6 times higher than that of 12CrNi2V. The sample with 6% V had the best wear resistance, which was 21 times greater than that of 12CrNi2V.

Cross wedge rolling has the advantages of high production efficiency, good product quality, high material utilization, environmental protection, and low cost. It is one of the best processing methods for producing shaft blanks. In this paper, a cross wedge rolling die of TC4 titanium alloy is studied. Based on the Archard wear model, a modified model suitable for cross wedge rolling die wear analysis is derived through finite element simulation. Then, the modified Archard wear model is imported into Deform-3D software for finite element analysis. Orthogonal experimental design is used to combine and analyze different process parameters. Finally, the beetle antennae search (BAS)-genetic algorithm (GA)-back propagation neural network (BPNN) algorithm is used to predict the degree of die wear and to optimize the simulation parameters, which can acquire the process parameters that have the least impact on die wear. The results show that the wear distributions of cross wedge rolling tools is uneven. In general, the most serious areas are basically concentrated in the wedge-shaped inclined plane and rectangular edge lines. The reason is that the tangential force and radial force received by the die are relatively large, which leads to increased wear. Moreover, the temperature change is most severe on the wedge-shaped ridge line. When in contact with the workpiece, the temperature rises sharply, which makes the local temperature rise, the mold hardness decrease, and the wear accelerate. Through response surface method (RSM) analysis, it is concluded that the deformation temperature is the main factor affecting wear depth, followed by the forming angle, and that there is an interaction between the two factors. Finally, the feasibility of the BAS-GA-BP algorithm for optimizing the wear behavior of dies is verified, which provides a new process parameter optimization method for the problem of die wear in the cross wedge rolling process.
