Abstract AR
في هذا البحث تطوير طلاء سيراميك زجاجي جديد، و تمت عملية الطلاء بدون معامل كيميائية مسبقة للسطح، بإستخدام تقنية التغطيس على المعدن الأساس.
وتم تصميم الطلاء لإستخدامه لكافة أنواع الفولاذ السبائكي.
تم إجراء التعامل الحراري عند درجات حرارية (500, 550, 600) درجة مئوية وعند فترات زمنية مختلفة (120 & 60) دقيقة مع إضافة كوارتز بنسبة تتراوح بين (15 – 0) % للحصول على سيراميك زجاجي ذو خواص طلاء عاليه.
Abstract EN
In this work, a new glass-ceramic coating has been developed and applied, as a single coat without prior chemical treatment of the surface, by using the dipping technique on metal substrate.
the coating are designed for application on varies grades of low alloy steel, the selected substrate was low carbon low alloyed steel with (0.2)%C.
Various heat treatments at temperatures ( 500,550, and 600˚C ) at different times (60 & 120)min and with quartz addition in the range (0-15)% were used to obtain a glass-ceramics that have the optimum coating properties.
These coating have been characterized by x-ray diffraction analyses and the results showed presence of a number of microcrystalline phases which are formed during the heat treatments.
The results of corrosion resistance tests indicated that the acid resistance was greatly improved by addition of quartz into enamel frit but at same times decreased the alkali corrosion resistance, while the heat treatments improved both acid and alkali resistance for all cases, this is attributed to the formation of complex network from crystalline phases.
The results also indicated that the heat treatment at 600˚C for 120min with 15% quartz addition brought the optimum values for acid resistance property which are improved by 86.66%, while the optimum values for alkali resistance property was brought with free quartz added samples which were treated at 600˚C for 120min.
Mathematical modeling is implemented and regression equations are obtained by using ( SPSS ) software to predict the experimental data for acid and alkali corrosion rate.
Comparing the predicted and measured values gives high prediction accuracy.
The accuracy of prediction has been (82.58%, and 96.7%) for acid and alkali resistance properties respectively.
