Wear and corrosion are two main ways of workpieces failure. To monitor the status of workpieces, the complicated measurement techniques such as acoustic emission, photothermal radiometry, ultrasonic vibrations and ferrography, etc. have been employed, in which various kinds of advanced sensor detectors have to be used to get the requiring information. Although highly successful, all those techniques are time-consuming and costly. The proposed project is aimed to develop a new generation of tribo-corrosion resistant coating and an in situ wear/corrosion monitor by illuminating using a combination of novel tribo-corrosion resistent materials, detonation-gun spraying process and phosphorescent/fluorescent particles. The phosphorescent/fluorescent compostie coatings are indistinguishable under normal lighting, but emit a constant glow under ultraviolet light. Thus, the wear and/or corrosion would be samply monitored.. The coupling and matching between phosphorescent/fluorescent light indicating particles and functional coating materials, fabrication processes and the coating functions will be deeply investigated. It involves the development of novel light-emitting and tribo-corrosion resistant composite coatings by detonation-gun spraying process; the investigation of the effect of preparation process factors on illuminating thermal degradation, luminescence quenching of the phosphorescence/fluorescence and response measurement on the same time; the investigation of interfacial mechanical performances between the sprayed functional coating materials and the phosphorescent/fluorescent indicator particles; the investigation of inherences of functional tribo-corrosion coatings materials on thermal illuminating degradation, luminescence quenching of the phosphorescence/fluorescence and the response measurement. Such a combination of functional tribo-corrosion resistant coating and an in situ wear/corrosion monitor with phosphorescence/fluorescence indicators is low cost and high throughputs, which enable in situ wear/corrosion detecting on the tribo-corrosion coatings and prevents damage to the expensive underlying base.. The implementation of the proposed project will possibly provide theoretical guidance and technological foundation for practical corrosive and/or wear industry.
