Steel-based surface chrome-contained abrasion-resistant ceramic coating and preparing method of steel-based surface chrome-contained abrasion-resistant ceramic coating
The invention relates to a steel-based surface chrome-contained abrasion-resistant ceramic coating layer and a preparing method of the steel-based surface chrome-contained abrasion-resistant ceramic coating, and belongs to the technical field of methods for preparing steel-based protective coatings. The steel-based surface chrome-contained abrasion-resistant ceramic coating and the preparing method are characterized in that the steel-based surface chrome-contained abrasion-resistant ceramic coating is composed of silicon carbide ceramic abrasion-resistant powder, silicon dioxide, water glass, ferrochromium powder and the like; structure defects are overcome through the ferrochromium powder, the compactness of the coating structure is improved, and the metallurgical bonding strength between the coating and a steel base is greatly improved. By means of the preparing method, as a two-time curing technology is adopted, the curing time can be shortened, the coating quality can be improved, and a ceramic phase between the steel base and the coating can be easily generated; meanwhile, the coating has the abrasion resistance several times higher than that of the steel base, and the overall performance such as the surface rigidity and the corrosion resistance of the coating is improved. The preparing method is simple, construction is convenient, the production efficiency is high, and the economical effect and the practical effect are achieved. The problem that as a ceramic coating prepared in the prior art is poor in structure compactness, the overall performance of the ceramic coating can not be guaranteed through one-time curing is solved.
