摘要：
The SiC/AlSi10Mg composites were fabricated via selective laser melting(SLM). (SLM ). The phase characteristics, , microstructure, , anti-corrosion and wear resistance properties of SLM SiC/AlSi10Mg and SLM AlSi10Mg samples were investigated by XRD, , SEM, , EDS, , EBSD, , electrochemical test, , and friction and wear test. The results show that in the 3. 5% (mass fraction) ) NaCl solution, , the corrosion current density of SLM SiC/AlSi10Mg (2.0827 mu A/cm(2)) is lower than that of SLM AlSi10Mg (3. 389 mu A/cm(2)), and the passivation film on the surface of SLM SiC/AlSi10Mg (7. 1 nm) ) is thicker than that of SLM AlSi10Mg (1. 9 nm), ), indicating the SLM SiC/AlSi10Mg sample has better corrosion resistance than that of SLM AlSi10Mg. The reason can be attributed to that the addition of SiC causes the grain refinement, , the increase of high grain boundary, , and the interruption of the continuity of Al matrix, , leading to the decrease of corrosion rate and the increase of corrosion resistance. In addition, , the average microhardness for SLM SiC/AlSi10Mg composites (207. 68 +/- 16. 02)HV0.2 is twice that of SLM AlSi10Mg alloy (103. 58 +/- 7. 41)HV0.2 , indicating its hardness and wear resistance are improved. Both the wear mechanisms of SLM AlSi10Mg and SiC/AlSi10Mg composites are mainly abrasive wear and oxidation wear.
