▎ 摘 要
NOVELTY - Heating material surface involves exposing the surface to an electromagnetic radiation source emitting a first wavelength spectrum; receiving a second wavelength spectrum from the surface using a detector at a sampling frequency, where the first wavelength spectrum and second wavelength spectrum not greater than 10% overlap, where the overlap is the integral of intensity with respect to wavelength. USE - Method for heating material surface. ADVANTAGE - The method enables to heat material surface, where material has heat-resistant, and corrosion-resistant properties.
