The effect of solid boronizing at 950°C for 2 and 4 h on the phase composition, microstructure, hardness and abrasive wear of steel AISI 304L is studied under the impact of a flow of hard particles. The boronized steel is shown to consist of three layers (metal boride, porous layer and matrix) from the external surface to the center. The hardness of the boride is much higher than that of the matrix phase. The wear resistance of the steel is the highest after the 2-h boronizing, and the wear depends on the angle of impact of the hard particles on its surface. With growth of the duration of the boronizing the wear behavior of the steel changes from ductile one to brittle one.

研究了在硬质颗粒流动的影响下，在 950°C 下进行 2 小时和 4 小时的固体渗硼对钢 AISI 304L 的相组成、微观结构、硬度和磨料磨损的影响。硼化钢从外表面到中心由三层（金属硼化物、多孔层和基体）组成。硼化物的硬度远高于基体相的硬度。渗硼2h后钢的耐磨性最高，磨损取决于硬质颗粒对其表面的冲击角度。随着渗硼时间的增加，钢的磨损行为从韧性的一种转变为脆性的。
