Abstract

Abstract: Microstructure, mechanical properties and wear resistance of low alloy wear resistant steel were analyzed by means of scanning electron microscope, impact testing machine and dynamic load impact abrasive wear testing machine. The results show that the as-cast microstructure consists of pearlite and carbide, of which the macroscopic hardness, the impact absorbed energy and wear loss are 41.3 HRC, 6.1 J and 1.4378 g, respectively. And after quenching in sodium silicate (Na₂SiO₃) and PAG, the microstructure of the is both transformed into tempered lath martensite and carbide, of which the macroscopic hardness, the impact absorbed energy and wear loss are 49.0 HRC and 51.1 HRC, 7.3 J and 9.4 J, 0.9378 g and 0.835 g, respectively. Compared with the as-cast alloy, the macroscopic hardness, impact propekly and wear resistance of the PAG quenched steel are improved by 23.7%, 54.1% and 1.7 times, respectively. Compared with quenching in sodium silicate solution, the macroscopic hardness, impact property and wear resistance of the PAG quenched steel are improved by 4.3%, 28.8% and 1.1 times, respectively.

Key words: sodium silicate solution quenchant, in PAG solution quenchant, low alloy wear resistant steel, wear resistance, microstructure
