A Comparative Study of MO Films Deposited on AISI 310 and Alumina Surface Using Anodic Vacuum Arc

Abstract

The Surface of Alumina and Stainless Steel was considered for thin film deposition of molybdenum by using Anodic Vacuum Arc. The evaporation was carried out at 0.07 mbar pressure and at a welding current of 60 Amperes where the temperature reached beyond 2500˚C and a thin layer of molybdenum was coated on the substrates. The corrosion rate, surface morphology, crystallite size and lattice strain were calculated by using Electrochemical Analyzer, Scanning Electron Microscope and X-Ray Diffraction respectively.
