“…In the past two decades, the cladding material system, which includes alloys, metal matrix composites, oxide ceramics, etc., has been well developed to form surface-reinforced coatings with desirable properties (wear/corrosion/oxidation resistance, etc.) for applications in aviation, traffic, and marine fields. − However, for the application of laser cladding in anode fabrication, a different set of properties is required. The alloy-type material is expected to precipitate in the solidified layer using laser microcladding.…”

Nanosized alloy-type materials (Si, Ge, Sn, etc.) present superior electrochemical performance in rechargeable batteries. However, they fail to guarantee cycling capacity and stability under high mass loading required by industrial applications due to low electric contact and adhesive strength, which has long been a challenge. This work proposes a rational design for an alloy-type anode via facile and versatile laser microcladding and dealloying. The proposed anode features a large-area porous network composed of continuous nano-ligaments, which consist of evenly distributed nanosized alloy-type material metallurgically bonded with conductive material. The fabrication of the structure is validated using Ge–Cu and Sn–Cu anodes, both exhibiting enhanced cycling stability at high areal capacity and rate performance in lithium-ion batteries. The enhancement is attributed to the structural features, which contribute to lithiation–delithiation stability and intact electron/Li ion transference path, as verified by in situ and ex situ transmission electron microscopy observations. More importantly, the critical solidification conditions of laser microcladding are provided by a multiphysics simulation, allowing for a thorough understanding of the structural formation mechanism. The study provides a possible approach to improve mass loading and performance of an alloy-type anode for practical application.

“…As the conditions of service become more stringent, materials are put forward for higher demands and the problem of material failure becomes more and more severe [1,2]. Based on the advantages of the small heat-affected zone and metallurgical bonding [3,4], laser cladding technology is widely applied in material failure repair [5]. Nevertheless, the residual stress caused by the extremely fast cooling rate will affect the service life.…”

Known as having a stress self-accommodation characteristic, the laser cladding shape memory alloy (SMA) coatings have been widely used in material failure repair. Nevertheless, their further development is greatly limited by their low microhardness (250 HV0.2) and corrosion resistance. Benefiting from the capability of refined grain and adjusted microstructure, rare earth oxides play a key role in improving the properties of materials. Herein, to improve the microhardness and anti-corrosion of laser cladding SMA coatings, different amounts of La2O3 were doped in SMA coating. The influence of the different La2O3 doping amounts on the phases, grain size and microhardness was studied. The anti-corrosion of the SMA/La2O3 composite coating was explored in 3.5 wt.% sodium chloride solution. Results showed that the grain of the SMA/La2O3 composite coating is significantly refined. When doping with 0.9 wt.%, the refinement rate reaches 19%. Furthermore, based on the Hall–Petch effect, the microhardness of the SMA/La2O3 composite coating is increased to 450 HV0.2. At the same time, the anti-corrosion of the composite coating is enhanced due to the smaller grain size and fewer defects.

“…In recent years, laser cladding technology has been widely used in the preparation of wear-resistant and self-lubricating coatings on the surface of Ti6Al4V alloys as a new surface modification method [6,7]. Compared with other thermal deposition methods such as atmospheric plasma spraying (APS), flame spraying (FS), high-velocity oxygenfuel (HVOF), detonation spray coating (DSC), etc., laser cladding provides a superior metallurgical bonding with the substrate, which means less spalling or cracking behavior and denser coatings [8][9][10][11][12][13][14][15].…”

Lubricating-reinforcing composite coatings were successfully prepared on Ti6Al4V using laser-clad Ti6Al4V/Ni60/Ni-MoS2 mixed powders with different Ni-MoS2 contents (25, 35, and 45 wt.%), and their microstructure and tribological properties were studied. The reinforcing phase TiC, Ti2Ni, and the lubricating phase Ti2SC were in situ precipitated while Ti2SC and Ti2Ni formed a mosaic coherent structure within the above three coatings. In the 25 and 45 wt.% Ni-MoS2 coatings, the microstructure distribution uniformity of the coatings was not effectively improved by the Ti2SC-Ti2Ni mosaic structure phase due to the lower or higher content of Ti2SC. In the 35 wt.% Ni-MoS2 coating, the forming quality of the coating was the best due to an appropriate amount of the uniformly distributed Ti2SC-Ti2Ni mosaic structure phase. Furthermore, the microhardness of the coatings gradually decreased as the amount of Ni-MoS2 increased. In the 35 wt.% Ni-MoS2 coating, due to the uniformly and diffusely distributed Ti2SC-Ti2Ni mosaic structure phase, the stable lubricating-reinforcing mosaic structure transfer composite films were formed during the progress of the friction and wear tests, which led to the optimal worn surface evenness and quality, the anti-friction and the wear resistance properties compared with the Ti6Al4V, 25 and 45 wt.% Ni-MoS2 coating.
