Abstract:
Real-Time Monitoring and Analysis of Thermal Spray Processes Using Machine Vision
The objective of this project is to develop innovative vision-sensing and processing
techniques that can be used for real-time visual monitoring and analysis of thermal
spray processes. Process R&D and real-time control for high-temperature material
coating processes are the main applications of the project. The same monitoring and
analysis technology can also find use in spray forming applications. The innovative
viewing system suppresses the intense light of the flame or plasma in the video image
and allows direct observation of the traveling coating particles. The advanced image
processing and analysis schemes will allow in-process determination of important
quantitative measures such as the pattern and gross velocity of the particle stream,
the velocity of individual particles, the powder mass flow rate, the geometry and
turbulence of the plasma or flame, and possibly the temperature of particle populations.
Phase I will include a brief review of related work, and analysis of application
requirements, particularly focusing on NASA needs, an investigation and prototyping
of the proposed vision sensing approaches, and investigation and prototyping of vision
processing approaches. On the basis of the above, needs for future R&D will be identified
and the Phase II effort will be planned.
In addition to direct benefits to NASA and the aerospace industry, where thermal
coatings are widely used in advanced propulsion system components, the project has
immediate applications in jet engine manufacture, overhaul, and repair in which thermal
spray coatings are also widely applied.
