“…Laser surface nitriding was initiated by the work of Katayama et al [1] and since then there have been a number of investigations, e.g., Refs. [2][3][4][5]. This treatment is accomplished through laser surface melting of the alloy in a nitrogen environment, which forms titanium nitride.…”

“…Desde entonces hasta hoy, se han llevado a cabo un número importante de trabajos de investigación en esta área, siendo actualmente un campo muy activo en todo el mundo, como muestran las publicaciones recogidas en los últimos años. La mayor parte de las nitruraciones láser, llevadas a cabo por diversos investigadores, han empleado el láser de CO 2 como fuente de energía [17][18][19][20][21][22][23][24][25][26][27] . En algunos casos, se realizan procesos de nitruración utilizando un láser Nd:YAG [28][29][30][31][32][33] .…”

“…En la nitruración de titanio puro comercial, Mridha y Baker [21] utilizan una potencia de 2,8 kW para optimizar los resultados. Zimnicki et al [20] , emplean 1 kW de potencia para obtener capas de TiN sobre una aleación TiAlMn. Sin embargo, existen algunos casos en los que se utilizan potencias menores con resultados satisfactorios.…”

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...

Nitriding is a well known technique to improve properties of materials. The process utilizing laser contains many different processes like heat transport and melting effects, diffusion and convection, which partially determine the synthesized coatings. This review concludes the research on titanium nitride synthesis in reactive ambient and draws conclusions for the general handling of the method. Afterwards, it becomes clear which and why, transport processes limit the coating properties. IntroductionHard material systems such as titanium nitride play an important role within the field of material sciences and industrial applications. In particular wear and corrosion protection are based on such systems. Beside the classical manufacturing procedures such as PVD or CVD, the method of the direct laser synthesis in a reactive gas environment, as examined here, represents an alternative to the production of such coatings. This review discusses the synthesis of such functional coatings on the system titanium -nitrogen by different laser irradiation based on own results respectively the literature and tries to give a general overview of the physical respectively transport processes taking place. Thus, experiments from the last three decades using similar experimental setups will be compared and discussed. Due to the availability of data of investigations utilizing titanium and nitrogen, this system was taken as a general model. After a discussion of several different experimental analyses and modelling results, the treatments get parameterized. This results in large potentials for technical applications. Finally, general conditions for the synthesis of such coatings with this procedure were set up. By means of these results it is possible to achieve purposefully predefined layer characteristics. The review concludes the most important publications containing research about this process. Thus, it could be assumed to be a reference in relation to laser nitriding or -carburizing. [4] or also hybrid procedures. A further alternative and very simple method is the direct lasers synthesis. The material is placed in a reactive gas environment and will be irradiated with laser light. Due to the developing physical and chemical effects coatings are synthesized, which possess special treatment dependent characteristics. Carburizing, nitro carburizing and/or nitriding are to most common methods from this field of processes. The method of nitriding particularly assists the improvement of tribological properties of surfaces. The surface hardness gets increased, whereby the wear resistance rises. Furthermore, these coatings are usually very non-reactive, which leads to an increase in corrosion protection. In the following the method will be studied more exactly and will be explained. Quantifying of the processes gets an important aim of the work. Arising phenomena will also be modelled. To do these investigations, the model titanium nitrogen has been used. It is a well known and often used system, and has been investigated ...
