Corrosion
- 1. Corrosion and aging of the structures commonly thought of aging time by which a material loses caracteristicasde quality, defining quality as the "degree of fitness of a good or service to satisfy the needs and desires of consumers the corrosion process must be related to the mechanism of aging, when after some time and since the beginning of the interaction with some kind of fatigue that can happen as a result of the use of the mechanical part, element, component or structure as cyclic or repetitive, including a structure that supports its own weight; synergistically material deteriorates so to surface problems that can even come from the same manufacture, through treatments that have been made either at surface or surface sud such as heat treatment, dives to apply metal, machined and even coatings surface preparations as can accommodate mechanically affect their internal intentions by inclusion or by modification of the thickness on time affect the material once the material properties begin to wane when determined by flow corrision reactions and the effect of material fatigue corrosion process involves interaction with the environment, where chemical reactions are required to generate or electronic corrosion products, which are chemically related to any of the environmental variables such as humidity, temperature develop, ph (chemical environment), and others such as those generated by mechanical work to accumulate over time, leading to cycles within the material which no longer responds to the original elastic behavior of the same effects that result occur the mechanism of aging, which accelerates the deterioration of the material and structure has a purpose for which no will longer fit due to a curve with a cadence that leads to the destruction of the structure by fracture mechanisms. a way to consider the degree to aging of materials is to monitor THROUGH inspections, measurements, statistics, analysis of logbook, corrosion mapping and appraisal of performance based on the natural aging foreseen all the above considerations are to be taken into account for the elaboration of the aging program of any structure and form its performance criterion, resulting in the trend of permanent stimulation time useful and safe life of a structure viewed from the optical capabilities materials that comprise inspections and procedures are part of predictive maintenance, which nondestructively uses different techniques to know the state of the material at surface, and volumetric superfial sud or interior material. The importance lies in the purpose of the inspection, choose ideal technique to achieve this objective and often you will monitor the characteristics of the material to be inspected. measurements can be considered as the determination of the remaining thickness of the material, compliance with tolerance and clearances elements and assemblies; finally, measurements that establish the condition in which they find as a material or joint structures as a
- 2. result of your use or mechanical work can undergo changes that lead to the understanding of their behavior through time management statistics for purposes of considering the degree of aging in a material or structure is located, lies in the knowledge base performed, the results of inspections, measurements, repairs made and the accumulated time use. good management of the statistics generated a trend that can anticipate future behavior and even the failure that results in accidents analysis refers to the evaluation of the cluster of events that compliance with maintenance programs, particularly the recuperative corrections have happened. this assessment generates a real trend as both the structure behaved materials corrosion mapping corresponds to the exhaustive inspection of a structure in which all problems including corrosion defects that are potential corrosion problems that may arise in the future are related, determining the location and level of corrosion present mapping should result aging behavior suffered by the materials of the structure inspections and procedures are part of predictive maintenance, which nondestructively, using different techniques that provide insight into the state of the material at surface, and volume of a sud seperficial into the material performance assessment of comprehensive income refers to the computer of the above items, which must be included in the program so that aging can be estimated life remanen of materials and structure, safety and working conditions. the comparison with the lifetime estimated from design and construction highlights the difference between the natural aging anticipated as a result of 'selection and strength of materials for construction. and modification of aging dad for use
