Abstract

The invention relates to an Fe-SiO2-TiO2 coating material and a preparing method thereof. The Fe-SiO2-TiO2 coating material comprises, by mass, 5-15 parts of Fe, 35-55 parts of SiO2, 0.5-2 parts of TiO2 and 0.5-1.5 parts of trace elements. The preparing method comprises the following steps that firstly, an Fe-SiO2-TiO2 nanometer ball is prepared through a gas atomization method; and secondly, the nanometer ball prepared in the first step is mixed with ground C, Mo, B and Co through a surface active agent protection method to prepare mixed powder. The hardness of an Fe-SiO2-TiO2 nanometer coating prepared through the Fe-SiO2-TiO2 coating material and the preparing method can reach HRC65, the density of the coating can reach 7.3 g / cm<3>, and the spraying thickness of the coating can reach 5 mm.

Description

technical field [0001] The invention relates to the technical field of thermal spraying materials, specifically a Fe-SiO 2 -TiO 2 Coating materials and methods for their preparation. Background technique [0002] Thermal spraying refers to a series of processes in which fine and dispersed metallic or non-metallic coating materials are deposited on the surface of a prepared substrate in a molten or semi-molten state to form a spray deposition layer. With people's production operations in various extreme environments, the use conditions of workpiece equipment are getting worse and worse. The existing ordinary spraying materials are difficult to meet the use requirements in harsh environments. Therefore, people need more scientific and reasonable proportioning and better product performance. Spraying material and spraying process. Contents of the invention [0003] In order to solve the problems of poor wear resistance and low hardness of traditional coatings, the present...
