Title: Method for evaluating rust stability of atmospheric corrosion-resistant steel
Inventor: KAJIYAMA HIROSHI
IPC: G01N33/20
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To evaluate the rust stability by measuring the Fe2+ ion concentration [Fe2+] and Fe3+ ion concentration [Fe3+] in the rust of an atmospheric corrosion-resistant steel to obtain the ratio of [Fe2+]/([Fe2+]+[Fe3+]). SOLUTION: The concentration of Fe2+ ion and Fe3+ ion in the rust are measured by the potassium dichromate titration method, the chelatometric titration method, etc. The ratio [Fe2+/([Fe2+]+[Fe3+]) is calculated from each measured ion concentration [Fe2+] and [Fe3+], and it is judged that the rust stability is higher as this calculated value is smaller. Since this method is used only for analyzing the ion concentration by sampling the rust, the rust stability can be easily evaluated even after the steel is assembled into a structure. This method is also applicable not only the atmospheric corrosion-resistant steel, but also the steel capable of forming the stable rust through the surface treatment, and the ordinary steel in which no rust stabilization can be expected.

Abstract: PURPOSE:To correct the form of a beam to a real circular shape and also to compensate a shift of an optical axis due to the wavelength dispersion, by putting two triangular prisms combined between a collimator lens and an objective lens. CONSTITUTION:The 1st triangular prism 13 for correction of beam form is combined with the 2nd triangular prism 14 serving as a polarized beam splitter between a collimator lens 12 and an objective lens 21. In such a constitution, a shift of an optical axis due to the wavelength dispersion can be vertually eliminated by using different materials to both prisms 13 and 14. While the beams given from a laser beam source 11 are turned into parallel beams through the lens 12 and then made incident on an end face 13A of the prism 13 at a prescribed angle. Thus the beam can be formed into a real circular shape by increasing its length in the short axis direction. Therefore it is possible to correct the real circular shape of the beam and to compensate the shift of the optical axis at a time.
