Abstract
The invention relates to a wear-resistant ceramiccoating material and a preparation method thereof, belonging to the technical field of ceramics. The wear-resistant ceramiccoating material contains the following ingredients in parts by weight: 25-35 parts of quartz, 30-40 parts of electro-melting corundum, 3-8 parts of mullite and 5-10 parts of aluminatecement. The method comprises the steps of uniformly mixing and stirring all the ingredients, melting for 1.5-2.0 hours at the high temperature of 1,500-1,550 DEG C, and drying, thereby obtaining the wear-resistant ceramiccoating material. According to the wear-resistant ceramic coating material, due to the addition of quartz, the mechanical properties are improved greatly, and the flexural strength and compressive strength are higher than those of metallic materials, so that the wear resistance of samples is improved.
Description
technical field [0001] The invention relates to a wear-resistant ceramic coating, in particular to a wear-resistant ceramic coating whose flexural strength and compressive strength exceed metal materials and a preparation method thereof, belonging to the technical field of ceramics. Background technique [0002] Wear-resistant coatings occupy a considerable proportion in energy and economic cost consumption in industrial fields such as building materials, thermal power generation and metallurgical mines. Taking the cement industry as an example, the downtime caused by wear and tear accounts for 50% to 55% of the total downtime. Equipment wear and tear has become one of the crucial factors that determine whether a cement company can operate well. Therefore, improving the wear resistance of industry-related parts, reducing the consumption of wear-resistant materials, and extending the service life of wear-resistant materials are of great significance to improving equipment ope...
