Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-fareast-font-family:"dejavu="" sans";="" mso-bidi-font-family:"times="" new="" roman";mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">The corrosion behaviour oflnconel-600 was investigated in hydrogen sulphide gas environment at a temperature of 800⁰C under atmospheric pressure. The apparatus used was a tubular furnace in which the sample was kept and the hydrogen sulphide gas was passed at a high temperature. It was found that the sulphidation in an atmosphere of hydrogen sulphide gas at temperature of 75⁰C followed the pa-rabolic rate law. Scale formation was also observed. X-ray diffraction study revealed that the surface consisted mostly of nickel suphide. It was found that at temperatures above850⁰C the Inconel-600 alloy got totally corroded in the presence of hydrogen sulphide.</span>
