Özet (Çeviri)
Remanufacturing is attractive as an environmentally friendly and cost effective solution for end of life components. If a remanufactured component is to be substituted for a new product, the manufacturer should guarantee that the recovered performance meets the like new product specifications and quality standards. Material condition is critica! to determine the recovered performance. The detection and analysis of material defects when assessing a component for remanufacture are critica! for their reuse. Before making a decision on whether to remanufacture a product or replace it, NOT is normally used to detect current condition of the product material. Non-destructive testing (NOT) technologies detect and assess material defects in a variety of industrial applications without causing permanent changes to the test specimen .. In this work, two of most popular NOT techniques, thermographic and ultrasonic (phased array, c-sean) testing techniques were investigated to detect and character the defect within the material. The results show that phased array ultrasonic NOT is the most powerful technique of those tested for detecting and characterizing sub-surface defects. However, for components that are poorly suited for testing with a phased array probe due to rough . surfaces, pulsed thermography is easier to be used to detect discontinuities that are close to the surface of a material. lndustries can employ either ultrasonic or thermographic NOT techniques depending test specimen and probable defects in the · material. Armed with the enough information on a material defect to be detected and characterised by NOT techniques, industries can make remanufacturing decisions regarding the dispositian of a component whether it may be safely reused at the required performance level and if any recovery processes would bring the component back to operation specifications ina cost effective manner.
