This group focuses on the surface engineering by assisted plasma. Main research topics are: Prototype design and construction for the thermochemical treatment of steel parts as well as prototypes for physical vapor deposition (PVD); Nitriding, carbonitriding and oxy- carbonitriding of steels (stainless steels 316L, special steels as ¿Incaloy¿, and titanium based alloys Ti6Al4Va); Thin film coatings on substrates for tribological systems, high performance components and metal dusting improvement that are required for applications in metalworking, automotive, aerospace and biomedical industry; Development of piezoelectric materials used as sensors. The built prototypes allow us to produce multilayer and multicomponent coatings with plasmas generated by DC, RF and microwave fields.
We also develop mathematical representation of kinetics growth in concomitant nitride layers as well as the mathematical representation of the effects in operating parameters related with the characteristics of thin films. We also perform the structural characterization of a wide variety of steels and thin films using scanning electron microscopy, transmission X-ray diffraction as well as micro and nano hardness and bolt testing.
