Campa-Castilla R. Méndez-Méndez R. López-Callejas Física, Astronomía y Matemáticas Nitriding Surface Hardening Surface Treatments This study reports the surface modification of AISI 304 stainless steel by applying nitrogen ion implantation by lowenergy plasma at different temperatures (380ºC, 400ºC, 440ºC). The temperature of the samples was adjusted by varyingthe implantation pulse width while keeping the voltage constant at 1.5 kV. Microstructure and phase characterizationwere carried out by scanning electronic microscopy (SEM) and X-ray diffractometry (XRD) respectively. The surfacehardness was determined by Knoop measurements, and the results show that the treatment increases up to two times thesubstrate hardness value. Additionally, it was found a direct dependence between the substrate temperature and thenitrided layer thickness. X-ray diffraction patterns indicate the shift of the peaks of the treated samples to lower anglesthan those of the untreated samples, which is a clear signature of expanded austenite. 2007 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94220401 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
