ResumenUna técnica comúnmente utilizada para la mejora de la resistencia a desgaste de las aleaciones de titanio es la nitruración de la superficie, utilizando la deposición física o química de vapor, la implantación iónica o el refundido de la superficie en atmósferas que contienen nitrógeno. En esta revisión se estudian los sistemas de nitruración con tecnología láser, utilizados para tratar la superficie de diferentes aleaciones de titanio. Las aleaciones de titanio son un material alternativo al acero, muy atractivo para aplicaciones que requieren alta resistencia a temperaturas elevadas, puesto que tienen una relación resistencia-dureza elevada y buena resistencia a corrosión. En aplicaciones que requieren buena resistencia a desgaste, las aleaciones de titanio suponen un problema, debido a sus pobres características tribológicas. La utilización de aleaciones de titanio junto con un tratamiento de nitruración adecuado, podría permitir la sustitución del acero en diferentes aplicaciones, consiguiendo una disminución en el peso de los componentes fabricados. Palabras claveNitruración; Tratamiento láser; Titanio; Tratamiento superficial. Review about laser nitriding of titanium alloys AbstractA common technique used to improve the wear response of titanium alloys is to nitride the surface, using chemical or physical vapour deposition, ion implantation or surface remelting in a nitrogen atmosphere. In this revision nitriding systems with laser technology are studied, used in titanium alloys surface treatments.For high temperature, high strength applications, titanium based alloys are an attractive light-weight alternative to steel, due to their high strength to weight ratio and corrosion resistance. In applications that require good wear resistance, titanium alloys pose a problem due to their poor tribological characteristics.Titanium alloys used with a suitable nitriding treatment could allow the replacement of steel in different applications, obtaining weight savings in fabricated components. KeywordsNitriding; Laser treatment; Titanium; Superficial treatment. INTRODUCCIÓNDurante los últimos años ha crecido el interés por los metales ligeros que poseen las propiedades necesarias para poder reemplazar aleaciones convencionales, como el acero. Las aleaciones de titanio son materiales atractivos por su excelente relación densidad-resistencia, su buena resistencia a corrosión y su resistencia a elevadas temperaturas. Este tipo de aleaciones se han utilizado, en los últimos años, en diferentes sectores industriales. Algunas de las aplicaciones más importantes han tenido lugar en el sector aeronáutico [1] ,donde el titanio se está utilizando en sustitución del acero, así como en ingeniería médica, donde la biocompatibilidad del titanio puro y algunas de sus aleaciones ha empujado su uso en un rango muy amplio de aplicaciones [2][3][4] . La mayor limitación de este tipo de material es su baja resistencia a desgaste. Se hace necesaria la formación de capas superficiales que mejoren el comportamiento ante fenómenos de...

“…6,7 A lot of studies have been conducted in the literature on intermetallic compound reinforced ceramic composite as a result of the improved properties they offer. [8][9][10] In this work, a composite of TiC/Ti6Al4V was produced and Ti 3 Al was formed in-situ. The effect of scanning speed on the quantity of the Ti 3 Al formed in-situ was studied and its influence on the microhardness and the wear-resistance properties was investigated in detail and reported.…”

The effect of scanning speed on titanium aluminide Ti3Al produced in-situ during laser metal deposited TiC/Ti6Al4V has been investigated and its effect on the microhardness and wear-resistance properties has been studied. In this study, the titanium alloy Ti6Al4V (an important aerospace alloy) was deposited in combination with titanium carbide TiC using a laser metal deposition process. The laser power was maintained at 3.2 kW throughout the deposition process. The powder flow rate and the gas flow rate were also kept at constant values of 2.88 g/min and 2 l/min, respectively. The scanning speed was varied between 0.015 and 0.105 m/s, and the influence of the scanning speed on the titanium aluminide (Ti3Al) produced in-situ was studied, and its effect on the wear resistance behaviour was also investigated. The study revealed that as the scanning speed was initially increased, the Ti3Al produced in-situ was found to increase and the wear resistance was found to improve. As the scanning speed was further increased beyond 0.06 m/s, the Ti3Al produced and the wear resistance were found to decrease. Keywords: laser metal deposition process, microhardness, microstructure, titanium alloy, Ti 3 Al, wear resistance Preiskovan je bil vpliv hitrosti skeniranja na in-situ nastanek titanovega aluminida -Ti3Al, izdelanega med lasersko depozicijo TiC/Ti6Al4V ter prou~evan je bil njen vpliv na mikrotrdoto in obrabne lastnosti. V tej {tudiji je bila titanova zlitina -Ti6Al4V (pomembna zlitina za letalstvo), nane{ena v kombinaciji s titanovim karbidom -TiC, s pomo~jo postopka laserskega nana{anja. Med postopkom nana{anja je bila vzdr`evana mo~laserja pri 3,2 kW. Hitrosti toka prahu in toka plina sta bili zadr`ani pri konstantnih vrednostih 2,88 g/min in 2 l/min. Hitrost skeniranja se je spreminjala med 0,015 in 0,105 m/s. [tudiran je bil vpliv hitrosti skeniranja na in-situ nastanek titanovega aluminide (Ti3Al) ter njen vpliv na obna{anje pri obrabi. [tudija je odkrila, da je za~etno pove~anje hitrosti skeniranja pove~alo in-situ nastajanje Ti3Al, pove~ala se je tudi odpornost proti obrabi. Pri nadaljnjem pove~evanju hitrosti skeniranja nad 0,06 m/s, je bilo ugotovljeno zmanj{anje nastajanja Ti3Al in zmanj{anje odpornosti proti obrabi.

“…Some researchers have used laser cladding to prepare a TiN/Ti 3 Al particle-reinforced composite on a titanium alloy surface [19,20]; some researchers have used arc cladding and powder made of Ti, BN, and Ni to prepare a TiN-reinforced nickel matrix composite on the surface of 16Mn steel [21]; other researchers have used the power metallurgy method to prepare a nanoscale Cu-based composite with TiN particles [22] In addition, Ti 2 Cu particles regarded as an inevitable reaction of copper and titanium are a hard and brittle phase and usually used as reinforced particles in copper matrix materials. However, TiN·Ti 2 Cu-TiN-reinforced copper matrix composites prepared in situ on the surface of a copper device using arc cladding has seldom been reported.…”

A TiN and TiN·Ti 2 Cu reinforced copper matrix composite layer was cladded onto a T3 copper substrate to improve the anti-wear performance of copper products by means of the nitrogen-shielded gas tungsten arc cladding method (N 2 -GTAC). Better than the traditional preparation method of TiN, the TiN particles in the cladding layer were in situ generated using N atoms of shielding gas and Ti atoms of pre-deposited metal powders. In addition, the composite phase TiN·Ti 2 Cu occurred in the cladding layer, which also had a positive effect on anti-wearing. As Ti increased, the amount and grain size of TiN·Ti 2 Cu and TiN increased as a result. The hardness of the cladding layer increased with the increasing amount of reinforced phase generated in the layer. The hardness of the layer reached a maximum of 410 HV, which is nearly 5.1 times greater than that of copper. The TiN·Ti 2 Cu-and TiN-reinforced phases improved the wear resistance of the cladding layers. The cladding layer with 15 wt % Ti had the longsest launch stage (600 s) and the lowest fiction coefficient (0.56).
