Title

Oxidation And Corrosion Behaviour Of Mild Steel Laser Alloyed With Nickel And Chromium

Abstract

Surface alloys were made on mild steel, coated with nickel and chromium using laser surface alloying. Mild steel was coated with a composite layer of nickel and chromium using the plasma technique. This was followed by laser irradiation using a continuous carbon dioxide laser. Oxidation and corrosion behaviour of these alloys was then determined by carrying out oxidation in air at 800 °C and corrosion tests at room temperatures in 1 n H2SO4. With a 75 μm layer of nickel and chromium each, it was possible to make surface alloys on mild steel, which had a chromium concentration of 6-7 wt%, but the nickel concentration varied from 10-20 wt%. Oxidation behaviour improved significantly over the as-coated specimen and aqueous corrosion improved considerably. © 1995 Chapman & Hall.
