Multilayer sol-gel zirconia coatings on 316 stainless steel

摘要: Multilayer alkoxide based sol-gel zirconia coatings were fired under two regimes. SET I by drying each layer at 380°C and then performing a final firing 800°C. For II coatings, was to 800°C in single firing. The structure of the found be thickness dependent. In addition, significant substrate reaction occur with increasing thickness. samples coating did not change significantly after 600 nm reached. Substrate also appeared lessened. This behaviour indicates that phase rate within during is related amount substrate. higher monoclinic present suggests changes occurring may dependent on total time
