Paper Abstract

Rapid tooling by plasma spraying is one of the important tasks in rapid prototyping and manufacture technology, stream temperature affects directly on the melting state of powders and the quality of sprayed tooling during spraying. Combining with CCD data collection devices and image processing technology, real-time diagnosis of plasma stream with high temperature and high speed, has been realized during spraying in this paper. The collecting principle and collecting methods in the field of high temperature are specially investigated, as well as the experimental system of real-time collection by using CCD cameras is developed. At the same time, fake color image processing is presented to analyze the law of temperature field distribution. The results are important to realize on-line feedback control of stream structure, and to study further on forming quality.
