“…As shown in Figure 13, there are a large number of wear debris in the crack, and the furrow through the crack is obviously deeper. Because the bionic coupling unit has good supporting function, 29 as well as hindering effect and dispersing effect, 30 the overall wear resistance of the bionic samples is better than that of the blank sample. However, due to the different angles of the bionic coupling single model, the impeding effect on the thermal fatigue crack is different, resulting in the number of cracks, and length of the crack is different, which directly leads to the difference in the weight loss and wear performance of the different angle models.…”

The failure of grey cast iron drum brake is mainly caused by thermal fatigue crack running through the top along the axial direction, which has the characteristics of regional failure. By using the advantages of laser fabrication technology, the single models with five different angles combined with the anti-crack ring were designed. The optical microscope, scanning electron microscope and X-ray diffraction were used to characterize the microstructure and phase of the drum brake material grey cast iron and the bionic coupling unit. Both single models and double combination models were tested for thermal fatigue and wear after thermal fatigue, respectively. The effects of angle on the thermal fatigue and wear resistance of the bionic coupling models were investigated. Experimental results show that the microstructure of the unit was better than that of the base grey cast iron due to the appearance of ledeburite, martensite and residual austenite after laser treatment. Besides, thermal fatigue crack has a great influence on wear performance. The thermal fatigue crack and wear loss weight are the least in the model with anti-crack ring + 45°angle, the main crack length is the shortest. The service life of the drum brake with the double combination bionic coupling model is increased by 50% compared with that of the untreated drum brake in bench test.

“…According to the experimental results, the wear properties at 45° were best. Therefore a stripe-like coupling bionic unit model when at a tilt angle of 45° was chosen, according to previous experience [15][16][17]. Therefore, a 400 W ND-Yag (YASKAWA) laser was used, and the laser parameters are shown in Table 1.…”

It is important to solve the partial fatigue wear of large forging dies, where the service life can be short. The purpose of this paper is to use laser remelting biomimetic technology to prepare a coupling biomimetic model combination on the mold surface, strengthen the local fatigue wear resistance of the mold, and extend the service life of the mold. Three types of laser energies were used to prepare the coupling biomimetic elements and analyze the microstructure and phase composition of the specific gravity melting zone. The biomimetic units were combined into a variety of coupling biomimetic models (fringe, mesh, and dense array models with different laser energies), and the number of fatigue cracks and the weight of wear loss of the coupling biomimetic model were compared at different temperatures. The mechanism of the coupling bionic model was analyzed, and the coupling bionic surface with a dense row structure was determined to have strong anti-fatigue wear performance. According to the Range Method, the relationship between wear and fatigue temperature and laser energy of the coupled bionic model was determined. Using DEFORM software to simulate the stress, temperature, and wear conditions of the front axle die surface, different coupling biomimetic model combinations were prepared on the abrasive surface. The die wear and cut edge width of the forgings were reduced after practical production, which proved that the laser bionic local strengthening method can effectively prolong the service life of a die.

“…In addition, biomimetic science, inspired by the various unique structures of natural organisms that have evolved over millions of years and formed to adapt to the living environment, has played a very effective role in the design and processing of materials [ 13 , 14 ].

In the context of energy conservation and emission reduction, more and more attention has been paid to the development of lightweight metal materials with both high strength and high toughness. Inspired by the non-smooth surface of natural organisms, a biomimetic surface with various spacing reticulate units of 7075 aluminum alloys was modified by laser cladding. The microstructure, microhardness and tensile properties of the various spacing units with CeO2-SiC-Ni60 were studied. The finer microstructure and the higher microhardness of various spacing units in comparison with that of 7075 aluminum alloys were obtained, no matter the strip-like treated region or the cross-junction region. Moreover, the best combination of strength and toughness of the biomimetic sample with 2.5 mm spacing reticulate unit was discussed. Finally, by combining the microstructure, XRD phase change, thermal gradient effect, thermal expansion coefficient difference and hard phase strengthening mechanism, it was concluded that the 2.5 mm spacing reticulate unit had the best ability to inhibit crack propagation, and the dispersive hard phases of Al3Ni2 and SiC played a major role in stress release of the matrix.
