Microstructure and sliding wear behavior of nanostructured Ni60-TiB2 composite coating sprayed by HVOF technique

► Nanostructured Ni60-TiB2 coating is sprayed by HVOF. ► Conventional Ni60-TiB2 coating is sprayed by HVOF. ► Properties of nanostructured coating are compared to conventional coating. ► Nanostructured coating has much higher fracture toughness and microhardness. ► Nanostructured coating has much better sliding friction resistance.
