The outcomes showed that the main stages of this composite finish were NbC, γ-Ni, Cr23C6, Ni3Si, CrB, Cr5B3, Cr7C3 and FeNi3. Lots of good in-situ NbC particles and various chromium carbide particles had been distributed into the γ-Ni matrix. The rise when you look at the mass small fraction of Nb and NiCr-Cr3C2 may lead to the increase in NbC particles into the composite coatings. As a result of the large hardness of NbC and chromium carbides, the micro-hardness and also the use weight re
