“…The oxide can avoid direct contact between the cladding layer and the rotating ring and reduce the volume loss of the cladding layer and improve the wear resistance of the cladding layers. Chakraborty and Fernández et al [40,41] also got a similar result, showing that the formation of oxide can increase the wear resistance of the cladding layer. Worn morphology of the NiCo30 cladding layer under high magnification is observed, as shown in Figure 8a.…”

Abstract:Ni-based alloy powders with different contents of cobalt (Co) have been deposited on a 42CrMo steel substrate surface using a fiber laser. The effects of Co content on the microstructure, composition, hardness, and wear properties of the claddings were studied by scanning electron microscopy (SEM), an electron probe microanalyzer (EPMA), X-ray diffraction (XRD), a hardness tester, and a wear tester. The results show that the phases in the cladding layers are mainly γ, M 7 (C, B) 3 , M 23 (C, B) 6 , and M 2 B. With the increase in Co content, the amounts of M 7 (C, B) 3 , M 23 (C, B) 6 , and M 2 B gradually decrease, and the width of the eutectic structure in the cladding layer also gradually decreases. The microhardness decreases but the wear resistance of the cladding layer gradually improves with the increase of Co content. The wear resistance of the NiCo30 cladding layer is 3.6 times that of the NiCo00 cladding layer. With the increase of Co content, the wear mechanism of the cladding layer is changed from abrasive wear to adhesive wear.

“…The local temperature at the surface contact point was very high, and the microhardness near these points decreased rapidly, resulting in plastic deformation. Fernández et al [43] studied the effect of WC content on the reciprocating wear of NiCrBSi alloy reinforced by laser cladding with WC. The mismatch between hardness and wear resistance was also observed.…”

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.

“…MMC claddings typically consist of crushed or spherical tungsten carbide particles embedded into an iron‐, cobalt‐, or nickel‐based matrix. The microstructure and the wear behavior of these claddings are generally well studied at room temperature, but only a few investigations focus on their particular wear behavior at elevated temperatures . At room temperature, abrasive wear tends to decrease with increasing hardness of the MMC cladding, i.e., with increasing content or size of the hard particles inside the matrix, respectively.…”

Laser metal deposition (LMD) is utilized to clad the surface of a miniaturized test roll (Ø 40 mm) of tool steel. The cladding consists of two layers: a nickel alloy as intermediate layer deposited onto the surface of the steel substrate, and a metal matrix composite (MMC) as top layer consisting of spherical tungsten carbide particles embedded into the nickel alloy matrix. The thermomechanical wear behavior of the cladding is investigated on a test rig, where the test roll is pressed against an inductively heated load roll. Multiple test runs up to several hours simulating industrial loading conditions are performed. The presented testing procedure enables predicting the time-dependent abrasive wear behavior of the cladding, in particular for hot rolling mill applications. After testing for 8 h at temperature of 650 C and at contact pressure of approximately 1 GPa, the maximum depth of the wear mark is about 0.12 mm. Partial cracking, debonding and dissolution of the tungsten carbide particles, as well as formation of iron and chromium oxides at the surface of the wear marks occur. However, as low abrasive wear is observed, the investigated MMC may potentially be applicable for cladding rolls in steel hot rolling mills.
