Microstructure and properties of CrB2-Cr3C2 composite coatings prepared by plasma spraying
Two different CrB2 composite coatings were prepared on TC4 alloy substrates by atmospheric plasma spraying CrB2-Cr3C2 and Cr-B4C composite powders. The microstructure, microhardness, toughness, scratch resistance and wear resistance of the as-prepared CrB2 composite coatings were investigated. The r...

| description | Two different CrB2 composite coatings were prepared on TC4 alloy substrates by atmospheric plasma spraying CrB2-Cr3C2 and Cr-B4C composite powders. The microstructure, microhardness, toughness, scratch resistance and wear resistance of the as-prepared CrB2 composite coatings were investigated. The results show that the phase composition of the CrB2-Cr3C2 composite coating did not change obviously compared with the composite powder. However, Cr reacted with B4C during the spray process and CrB2, CrB, Cr3C2, Cr7C3 phases were generated. Compared with the CrB2-Cr3C2 composite coating, the Cr-B4C composite coating had uniform microstructure, relatively low porosity, higher hardness and toughness, good scratch resistance and dry sliding wear resistance, which is attributed to the in-situ exothermic reaction between Cr and B4C.
•CrB2 composite coating was prepared by plasma spraying Cr-B4C composite powder.•Cr reacted with B4C during plasma spraying and CrB2, CrB, Cr3C2, Cr7C3 were generated.•The in-situ reaction of Cr-B4C had great influence on the properties of coatings.•The mechanical properties of the CrB2-Cr3C2 and Cr-B4C coatings were compared. |
