- Abstract:
-
The boron infiltration problem of 4Cr13 stainless steel was solved by adding rare earth compounds and optimizing the process parameters. The boronizing process of 4Cr13 steel obtained by orthogonal test method was: temperature 920 °C, time 8 h, and the optimal rare earth addition amount was 0.5% (mass fraction). The results showed that after the addition of rare earth elements, the thickness of the permeable layer increased, the micromorphology and density of boride were significantly improved, the predominant tissues of Fe2B and (Fe, Cr)2B were obtained on the surface, and the brittleness of the permeable layer decreased.
