Microwave synthesized composite claddings with enhanced cavitation erosion resistance

Slurry Erosion–Corrosion of Bimodal Complex Concentrated Alloy Composite Cladding

“…Figure shows the efficacy of the bimodal‐reinforced CCA cladding compared with other surface modification techniques and alloys. [ 18,40–44 ] The bimodal‐reinforced CCA cladding showed higher hardness than thermal sprayed coatings except the WC–Co–Cr coating. [ 40 ] The bimodal cladding showed nearly 2–4 times higher than Ni and Al 2 O 3 thermal sprayed composite coatings.…”

“…[ 41 ] The bimodal CCA cladding also exhibits 13% higher hardness than Stellite 6 coating. [ 18 ] The increase in the hardness for the bimodal CCA cladding compared with thermal sprayed coatings is attributed to the difference in the microstructure and composition. The presence of splat boundaries and pores lowers the hardness for the TS coatings, whereas the significant metallurgical bonding, lower porosity, and atomic diffusion from the substrate enhance the adhesion of the microwave claddings by limiting the delamination.…”

“…[37] A detailed description of strengthening mechanisms for the bimodal composite is explicitly described elsewhere. [18,37] Furthermore, the presence of Si in the cellular and intercellular regions (due to the SiC particle dissociations) also enhanced the hardness owing to solid solution strengthening associated with dislocation pinning. [37] On the contrary, the combined micro-and nanoparticle interactions also contribute to higher fracture toughness associated with crack pinning and blunting, where the microparticles aid in hindering crack propagation through deflection, and the existence of nanoparticles at the vicinity of microparticles increases the fracture energy owing to crack blunting.…”

“…Comparison of hardness and fracture toughness synergy of the microwave-derived CCA composite claddings with other coating/claddings and different CCA compositions. [18,[40][41][42][43][44] MC, microwave cladding; TS, thermal spray; LP, laser processing; SPS, spark plasma sintering; AM, arc melting.…”

Analysis of susceptor temperature during microwave heating and characterization of Ni-30Cr3C2 clads

“…[20][21][22][23][24] However, very less literature has reported about the clads produced for cavitation erosion resistance through microwave hybrid heating. 25 The objective of the current study is to optimize the microwave exposure time to develop clads through microwave hybrid heating and to characterize the developed clads for cavitation erosion resistance. The incubation time of the material increases logarithmically with the increase in the microhardness of the material.…”
