“…[5][6][7][8] This process is also believed to lower the production time of complex parts, to maximize material utilization, and is considered to be environmentally friendly. 9 Most of the SLM research is focused on the following alloys: (i) pure iron, stainless steel, and different tool steel grades in the directions of parameter optimization, structure optimization, and evaluation of mechanical properties [10][11][12][13] ; (ii) Al-based alloys, like Al-12Si and AlSi10Mg, mainly focused on parameter optimization and evaluation of various properties [14][15][16] (iii) Ti6Al4V (for high strength aerospace applications), pure titanium and beta titanium alloys (bulk and porous scaffolds for bio-medical applications) focusing on the parameter optimization and evaluation of related bio-medical, corrosion and mechanical properties [17][18][19][20] ; (iv) Ni-based alloys like nitinol, inconels, and waspaloys (for high temperature properties and shape memory effects) mainly focused on parameter optimization and high temperature properties [21][22][23][24] and (v) Co-based alloys (CoCrMo as dental implants) focused on the microstructure and biomedical properties. 25,26 Altogether, the majority of the research shows that parts produced by SLM have improved properties compared to parts produced by conventional casting/powder metallurgy techniques.…”

Al-12Si (80 vol%)-Ti 52.4 Al 42.2 Nb 4.4 Mo 0.9 B 0.06 (at.%) (TNM) composites were successfully produced by the selective laser melting (SLM). Detailed structural and microstructural analysis shows the formation of the Al 6 MoTi intermetallic phase due to the reaction of the TNM reinforcement with the Al-12Si matrix during SLM. Compression tests reveal that the composites exhibit significantly improved properties (;140 and ;160 MPa higher yield and ultimate compressive strengths, respectively) compared with the Al-12Si matrix. However, the samples break at ;6% total strain under compression, thus showing a reduced plasticity of the composites. Sliding wear tests were carried out for both the Al-12Si matrix and the Al-12Si-TNM composites. The composites perform better under sliding wear conditions and the wear rate increases with increasing loads. At high loads, the wear takes place at three different rates and the wear rate decreases with increasing experiment duration.

“…Los estudios que se están realizando con la tecnología SLM se centran en el desarrollo de parámetros de proceso, microestructura, corrosión, biocompatibilidad y evaluación de propiedades mecánicas, en materiales metálicos tales como aceros inoxidables y aceros de herramienta [4][5][6][7], aleaciones de aluminio del tipo Al12Si y AlSi10Mg [8][9][10], titanio C.P., Ti6Al4V y aleaciones de titanio beta [11][12][13][14], aleaciones base níquel (como nitinol, inconeles y waspaloys) para propiedades de alta temperatura [15][16][17][18], aleaciones base Co (CoCrMo, CoCrMoW) para implantes dentales [19,20], cobre comercialmente puro y aleaciones de cobre [21,22]. En conjunto, la mayoría de las investigaciones muestran que las piezas producidas por SLM tienen mejores propiedades que las producidas por técnicas convencionales, tal como la fundición [23].…”

RESUMENEn este artículo se investigaron las propiedades mecánicas y tribológicas de materiales compuestos de matriz de acero (acero inoxidable 316L reforzado con partículas cerámicas Cr3C2) procesados por tecnologías de fabricación aditiva de fusión selectiva con láser (SLM). Se estudió el comportamiento a desgaste con el ensayo "pin-on-disk" a temperatura ambiente y se observó la superficie desgastada mediante microscopía electrónica de barrido (SEM). Los resultados indicaron que el coeficiente de fricción no tiene una tendencia clara o relación directa cuando se varía el porcentaje de refuerzo mientras que la tasa de desgaste disminuye con el aumento del contenido de refuerzo. Las mejores propiedades se obtuvieron con un 6% en peso de refuerzo.

ABSTRACTThe mechanical and tribological properties of steel matrix composites (316L stainless steel reinforced with Cr3C2 ceramic particles) were investigated. The steel matrix composites (SMC) with three reinforcing percentages (3, 6, and 9 wt.%) were manufactured by Additive Manufacturing technologies (SLM: Selective Laser Melting). The wear behaviour was studied by using a pin-on-disk wear test at room temperature. The worn surface was analysed using Scanning Electron Microscopy (SEM). The results indicated that the friction coefficient does not have a clear tendency or direct correlation with the reinforcement variation while the wear rate decreases with increasing content of reinforcement. The better properties combination were achieved with 6 wt.% of reinforcement.
