Descripción del proyecto
TITANIUM AND ITS ALLOYS ARE OF HIGH INTEREST FOR TECHNOLOGICAL APPLICATIONS DUE TO THEIR EXCELLENT MECHANICAL PROPERTIES, HIGH CORROSION RESISTANCE AND GOOD BICOMPATIBILITY, FURTHERMORE, TIO2 AND OXIDE LAYERS ON TI HAVE ALSO BEEN ADDRESING A SIGNIFICANT ATTENTION DUE TO THE THEIR FUNTIONAL PROPERTIES SUCH AS SELF-CLEANING, ANTI-FOGGING, WETTABILITY, PHOTOCATALYSIS, BIOCOMPATIBILITY, ETC¿ HOVEWER, THE USE OF TITANIUM FOR ADVANCED APPLICATIONS ARE USUALLY RESTRICTED BECAUSE ITS LOW WEAR RESISTANCE AND HIGH OXIGEN REACTIVITY, THEREFORE, THE PRESENT PROJECT ATTEMPT TO OVERCOME THESE LIMITATIONS AND ALSO, FIND NEW MULTIFUNCTIONAL SURFACES ABLE TO MEET OTHER REQUIREMENTS FOR NEW APPLICATIONS, IN THIS SENSE, THE PRESENT PROJECT WILL EXPLORE THE USE OF SURFACE MODIFICATION TECHNIQUES SUCH AS ANODISING WITH OR WITHOUT FURTHER FUNCTIONALIZATION THROUGH SELF ASSEMBLY PROCESSES, ELECTROPHORETICAL DEPOSITION AND CHEMICAL DEPOSITION IN A FLUIDIZED BED REACTOR ( FBR-CVD) HEATED BY SOLAR ENERGY,THE ANODISING PROCESS IS ONE OF THE MOST PROMISING METHODS TO OBTAIN EITHER IMPROVEMENTS OF ADHESIVE BONDING AND ITS DURABILITY UNDER SEVERE ENVIRONMENTAL CONDITIONS FOR AERONAUTICAL APPLICATIONS, A BETTER BIOCOMPATIBILITY FOR IMPLANTS OR MULTIFUNCTIONAL SURFACES WITH SPECIFIC PROPERTIES SUCH AS PHOTOCATALYTICAL ACTIVITY OR CORROSION PERFORMANCE, AMONG OTHERS, MOREOVER, AS IT IS POINTED OUT IN THE LITERATURE, THIS TECHIQUE CAN OFFER NUMEROUS FUTURE APPLICATIONS ONLY BY CONTROLLING THE MICROSTURE OF THE TIO2 LAYERS, ADDITIONALLY, THE PRESENT PROJECT WILL TACKLE THE DEPOSITION OF ADVANCED CERAMIC COATINGS TO INCREASE WEAR AND OXIDATION RESISTANCE BY ELECTROPHORETIC DEPOSITION, THIS CONVENTIONAL TECHNIQUE WILL ALLOW US TO OBTAIN NEW COATINGS ABLE TO IMPROVE THE MECHANICAL, PHYSICAL AND CHEMICAL CHARACTERISTICS OF THE TITANIUM ALLOYS IN TERMS OF REFLECTIVITY AND COLOUR, RESISTANCE TO CORROSION, RESISTANCE TO WEAR, CATALYTIC REACTIONS, BIOCOMPATIBILITY, ETC, FINALLY, CHEMICAL DEPOSITION IN A FLUIDIZED BED REACTOR (FBR-CVD) HEATED BY SOLAR ENERGY WILL BE CARRIED OUT TO MODIFY TITANIUM SURFACES, THE USE OF THIS ENVIRONMENTALLY FRIENDLY TECHNOLOGY (USED SOLAR ENERGY TO HEAT THE FLUIDIZED REACTOR) IS A NEW CHALLENGE IN THE MATERIALS TREATMENT FIELDS DEPOSITING CONTROLLED MICROSTRUTURE COATINGS, FURTHEMORE, THE INDUSTRIALLY EXPLOTATION OF THIS TECHNOLOGY IS A LONG TERM OBJECTIVE OF THE PROJECT, Titanio\funcionalización\aeroespacial\biocompatible\anodizado\deposición electroforética\lecho fluidizado calentado por energía s
