“…Hemmati et al [36] also reported that Fe content over 40 wt.% entirely suppressed the precipitation of primary Cr borides. According to the previous research results [1,[34][35][36][37][38], areas 1 and 2 of the SLD coating, labeled in Fig. 3e, are Cr m C n /Cr 3 B/Ni 3 Si 2 /FeNi n eutectics and c-Ni/FeNi n solid solution, respectively; while areas 3 and 4 of the LC coating, labeled in Fig.…”

“…Observa-se que ocorreram mudanças entre a microestrutura do primeiro e segundo cordão que podem ser associadas a variação da diluição. Considerando a morfologia dos microconstituintes [7], a microestrutura do primeiro cordão é composta principalmente por carbonetos Cr 7 C 3 (ripas, meio tom) e boretos CrB (regiões escuras), pontos 1 e 2 respectivamente indicados na Figura 5a. Já na microestrutura do segundo cordão, com menor diluição (Figura 5b), observa-se a intensa formação do boreto Cr 5 B 3 (ponto 3 -estrela), Ni 3 B (estrutura ramificada) e carboneto Cr 7 C 3 (ponto 4 -ripas).…”

“…O crescimento do boreto Cr 5 B 3 , sobre o CrB, é controlado pela difusão de B e Cr, assim pode-se associar a elevada taxa de resfriamento do processamento por HPDL com comprometimento do crescimento do boreto Cr 5 B 3 . [7].…”

“…Hemmati et al investigated the microstructure and phase formation of laser cladded Ni-Cr-B-Si-C hard-facing alloy. They found that Ni-Cr-B-Si coatings consisted of different kinds of Cr boride, Cr carbide, dendrites of Ni solid solution and Ni-B-Si eutectics, and the microstructure depend on alloy compositions and processing parameters [14][15][16]. In summary, these works on additive Any further distribution of this work must maintain attribution to the author(s) and the title of the work, journal citation and DOI.…”
