A number of Ti02 and P20 5 nucleated glass-ceramic coating compositions in the system RO-R'20-Al20 3-Si02 (R = Ca, Mg; R' = Na, K, Li) have been studied for application on various grades of steel and alloy with a view to protecting them against mechanical wear and chemical corrosion. Good adhesion of the coating has been obtained on mild steel, stainless steel and nimonic alloy. The conventional technique has been used in the preparation and application of the coating material. The nucleation and crystal growth have been achieved by suitable heat-treatment schedule of the coated specimen. The properties of the coatings with respect to resistance towards abrasion, impact, high temperature, thermal shock and chemical corrosion have been evaluated and found to be superior to those of the conventional vitreous enamel coatings. X-ray and electron microscopic studies have been used to analyse the crystalline phases formed in the coating during the heat-treatment process. The unique combination of properties achieved in this new class of coating material could be highly useful for a number of specialized engineering and industrial applications for preventing failure of metals under stringent operational conditions.
