摘要

Surface microstates of real surfaces of solid materials change in industrial environments, or they are changed in industrial surface processes positively. A real time diagnosis technique for the surface microstates should be developed for the process control. We propose a diagnosis technique for temperature and microstructure of real surfaces on a basis of the hardware performance of our wide-spectral-range highspeed spectrophotometer system. With respect to the temperature, an active spectral pyrometer technique is adopted, in which the reflection of the surface is measured as well as the self-emission. With respect to the microstructure, an attention is paid to the interference and diffraction of radiation in a new real surface model. An experiment is made on a metal surface in a high-temperature air-oxidation process to verify the performance of this technique. Spectra of emission and reflection energy of radiation in a near-infrared through infrared region are measured at every 2 s, and analyzed. Time transition of the surface temperature of an order of 1100 K is estimated within an inaccuracy of 10 K. The average thickness d and rms roughnessσ{sub}I of the surface film are estimated to be in regions of d=0.08～3.8μm and σ{sub}I=0.01～0.71μm, respectively.
