Abstract:In this work, the effects of NbC additions on the microstructure and mechanical properties were examined. In order to do this, NbC compounds were added into the Fe matrix at the weight percentage of 0.1-2 with individually to obtain powder mixture. The microstructure of the powder metallurgy (PM) steels were characterized by optic microscope, scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). Experimental results indicated that NbC alloyed steels can be produced by PM technology. An increase in strength was observed when the amount of NbC compounds increased for all PM steels. The precipitation of carbides and nitrides in these steels limits austenite grain growth and increases the precipitation hardening or clustering hardening that results in significant improvement in strength.

This paper reviews progress over the last five years in the field of laser surface modification of titanium alloys. The authors analyze the effect of new laser technologies and new materials as tools for improving surface properties-specifically, biocompatibility and resistance to wear, corrosion, and high temperatures. The authors discuss the effect of laser processing parameters on the microstructure and compare the results obtained by various researchers. Therefore, an overview of the difficulties involved in the laser processing of titanium is provided with a discussion of future prospects.

“…Entre estos refuerzos, el TiC es un firme candidato para ser utilizado, debido a su elevada dureza, alto punto de fusión y buena estabilidad termodinámica que lo hace apto para reforzar matrices de hierro y de acero (Xinhong et al, 2006;Sun et al, 2010;Zhong et al, 2011). Por lo tanto, se espera que el material compuesto resultante presente un mejor comportamiento al desgaste (Doǧan et al, 1999).…”

RESUMEN:En este estudio se muestra un análisis del comportamiento del coeficiente de desgaste en seco de compuestos de matriz metálica (MMC), base acero inoxidable 316 reforzado con partículas de carburo de titanio (TiC) de acuerdo con la norma ASTM G 99-05 en un tribómetro para la realización de ensayos de desgaste mediante el contacto y rozamiento de dos materiales entre sí, uno en forma de disco y otro en forma de varilla o bola (pin-on-disk). En el estudio se evalúa el efecto que tiene el porcentaje de refuerzo en los MMC fabricados con 3, 6 y 9% (vol.) de TiC, en muestras compactadas a 800 MPa, dando lugar a diferentes valores de tamaño de grano, dureza y densidad, los cuales son sinterizados por medio de descarga luminiscente anormal, a una temperatura de 1200 °C ±5 °C, con atmósfera de protección de H 2 -N 2 y tiempo de permanencia de 30 minutos. De acuerdo a los resultados obtenidos se concluye que la mejor condición de fabricación de los MMC, se consigue cuando la mezcla contiene 6% de TiC, alcanzando el menor tamaño de grano, la mayor dureza y el más bajo coeficiente de fricción. En este sentido, se observó que la incorporación de partículas de cerámica (TiC) en matriz de acero austenítico (316) presentan mejoras significativas en la resistencia al desgaste. ABSTRACT: Effect of the percentage of reinforcement on the wear in the metal matrix composites sintered with abnormal glow discharge.In this study an analysis of the behavior of dry wear coefficient of a Metal Matrix Composite (MMC) in 316 stainless steel reinforced with particles of titanium carbide (TiC) according to ASTM G 99 standards, in a pin-on-disk test. In this research it is tested the effect of the percentage of reinforcement in the MMC manufactured with 3, 6 y 9% (vol.) of TiC, in samples compacted at 800 MPa, generating different values of grain size, hardness and density, they are sintered with abnormal glow discharge, at a temperature of 1200 °C ±5 °C, with a protection atmosphere H 2 -N 2 and a permanence time of 30 minutes. According to the results obtained it is concluded that the best condition for the MMC manufacturing, in relation to the reinforcement percentage, is the one obtained when the mixture contains 6% of TiC compacted at 800 MPa. In these conditions, it was obtained: achieving smaller grain size, the greater hardness and the lowest coefficient of friction. In this respect, it was observed that the incorporation of the ceramic particles (TiC) in a matrix of austenitic steel (316) shows significant improvements in the resistance to the wear.
