Microstructure and corrosion behaviour of WC/NiCrBSi coatings by vacuum cladding

H. F. Zhang et al.

Summary: WC-NiCrBSi and IWC-NiCrBSi coatings were fabricated on SS 316 L using vacuum cladding process to investigate their phase constituents, microstructure, chemical composition, and corrosion and cavitation resistance. The IWC-NiCrBSi coating showed better cavitation resistance compared to the WC-NiCrBSi coating.

Influence of the Cu content on the electrochemical corrosion performances of Ni60 coating

Xiaotian Yang et al.

Summary: The experimental study found that the Cu element can enhance the orientation growth of Ni-based coatings and improve their corrosion resistance. When the Cu content reached a certain level, the corrosion resistance of the coating began to decrease, but it was still better than that of the coating without Cu element.

Microstructure and corrosion resistance of Fe-based coatings prepared using high-speed laser cladding and powerful spinning treatment

Qiaofeng Bai et al.

Summary: Fe-based alloy coatings prepared using high-speed laser cladding technology with powerful spinning treatment exhibited refined surface layer grains, increased volume ratio of intergranular ferrite, more alpha-phases, and higher corrosion resistance in 3.5% NaCl solution. The anti-corrosion mechanism was attributed to grain refinement, phase composition, and elemental content.

Influence of Ni content on the microstructure and reciprocating wear of Fe-based/B4C composite coating by vacuum cladding

Huan Yu et al.

Summary: Fe-based/B4C composite coatings with and without Ni addition were fabricated on steel surface via vacuum cladding. The addition of Ni improved the hardenability of the coating matrix and formed tough martensite, leading to a relatively stable microhardness and optimal sliding wear performance. The main wear mechanisms of the coatings with different Ni addition were identified as oxidative, adhesive, and abrasive wear in dry sliding conditions.
