The formation of the elemental phosphorous layer will acts as a diffusion barrier against nickel dissolution and the passivation is attended .With 9.0M HCl solutions an increase of Ni dissolution will occurred ,pitting corrosion is found. X-ray photo-electron spectroscopy (XPS) and is used to confirm these suggestions. The study of immersion time gavepassivation and pitting corrosiondepending on the time immersion.  ISSN : 1012-1319  Journal Name : Science Journal  Volume : 23  Issue Number : 2  Publishing Year : 1427 AH 2007 AD  Article Type : Article  Added Date : Sunday, June 22, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email سناء طاهر عرب Arab, Sanaa Taher Researcher Doctorate dr.s.arab@hotmail.com Files File Name Type Description  34006.pdf pdf ملخص البحث  36919.pdf pdf البحث Back To Researches Page
