NiCrSiB-based сomposite powders with 10, 20, 40 wt.% TiB2 particles content were deposited on steel substrates by plasma spraying. The structure of NiCrSiB-TiB2 coatings consists of Ni-based matrix and TiB2 and CrB grains. Among the coatings studied, the NiCrSiB-20wt.%TiB2 shows excellent wear-resistance. The worn surfaces were observed using scanning electron microscopy and Auger electron spectrometry analysis to determine the wear mechanisms.entitanium diboridenikel-based self-fluxing alloycermetwear mechanismArticle
