Magnesium coatings were fabricated on staonless steel substrates (1Cr11Ni2W2MoV) by a plane magnetron sputteringtechnique. The argon pressure and the substrate condition (including temperature and the substrate was rotated orfixed) were varied in order to evaluate the influence of the parameters on the crystal orientation and morphology of thecoating. The corrosion behavior of the coatings in l wt pct NaCl solution was studied by electrochemical methods.The results showed that all coatings exhibited preferred orientation (002) as the argon pressure increased from 0.2 to Magnesium coatings were fabricated on staonless steel substrates (1Cr11Ni2W2MoV) by a plane magnetron sputteringtechnique.
