Abstract

En 中文

• Mo and B4C synergistically tailor Fe50Mn30Co10Cr10 HEA composite coatings. • In situ TiB2/TiC phases replace the FCC + σ microstructure gradually. • Ceramic phases evolve from fine particles to flower-like dendrites. • C2 shows the best wear resistance with the lowest friction and wear loss. • C3 achieves 883 HV hardness and the best corrosion resistance.
