The actual development of electronics and computers has allowed developing methods for measuring corrosion in real time and at very short periods. The generation of new knowledge has allowed using physicochemical methods to determine corrosion very fast and store the data obtained. The information contained in patent documents claiming these new advanced technologies is of great value to generate knowledge that respond to the problems and needs of the R + D + i related to the continuous measurement of corrosion in transport vehicles and other instruments and equipment. Distance monitoring is important in these cases where the vehicle is moving. It is very important for operation and maintenance and for the evaluation of the protective products against corrosion. The aim of this paper is to generate new knowledge from the application of the methodology Generation and Knowledge Management (MGGC), from which the search strategy that inventions claiming keywords recovered was determined: corrosion sensor and monitoring, patent databases freely available on internet. The results obtained from the processing of the information contained in these patent documents identified the strategic objectives of an R + D + i related corrosion monitoring by sensors.

Corrosion of reinforced concrete infrastructure is the principal cause of failures and consequently lost in construction industry. Marine environment is known as a very aggressive environment due to salts transported by the breeze is deposited over metallic materials surfaces and provoke their corrosion. Reinforced concrete specimens elaborated with water/cement ratios 0.45 and 0.65 were exposed to tropical marine environment at Campeche, Mexico, 300 m to coastline. In closeness, a thermoelectric plant is located, which releases sulfur dioxide, this pollutant reacts with humidity and generate acid depositions. Meteorological variables as temperature, relative humidity, precipitation, wind direction as well as chloride and sulfur dioxide concentration in atmosphere were monitored seven years to relate their contribution to concrete deterioration. Besides, electrochemical parameters as half-cell potential, corrosion rate and electrical resistivity were measured. Results show that in spite of high relative humidity, temperature and humectation time, chloride and sulfur dioxide concentration, the corrosion process, determined by electrochemical techniques, have not started. Good properties of specimens are attributed to excellent quality of materials utilized and correct dosage used to elaborate them, which provide them durability. [ABSTRACT FROM AUTHOR]
